11.写入文件属性
#!/bin/bash
#修改存放在ext2、ext3、ext4、xfs、ubifs、reiserfs、jfs等文件系统上的文件或目录属性，使用权限超级用户。
#一些功能是由Linux内核版本来支持的，如果Linux内核版本低于2.2，那么许多功能不能实现。同样－D检查压缩文件中的错误的功能，需要2.5.19以上内核才能支持。另外，通过chattr命令修改属性能够提高系统的安全性，但是它并不适合所有的目录。chattr命令不能保护/、/dev、/tmp、/var目录。
chattr [-RV] [-+=AacDdijsSu] [-v version] 文件或目录
－R：递归处理所有的文件及子目录。
－V：详细显示修改内容，并打印输出。
－：失效属性。
＋：激活属性。
= ：指定属性。
A：Atime，告诉系统不要修改对这个文件的最后访问时间。
S：Sync，一旦应用程序对这个文件执行了写操作，使系统立刻把修改的结果写到磁盘。
a：Append Only，系统只允许在这个文件之后追加数据，不允许任何进程覆盖或截断这个文件。如果目录具有这个属性，系统将只允许在这个目录下建立和修改文件，而不允许删除任何文件。
i：Immutable，系统不允许对这个文件进行任何的修改。如果目录具有这个属性，那么任何的进程只能修改目录之下的文件，不允许建立和删除文件。
D：检查压缩文件中的错误。
d：No dump，在进行文件系统备份时，dump程序将忽略这个文件。
C：Compress，系统以透明的方式压缩这个文件。从这个文件读取时，返回的是解压之后的数据；而向这个文件中写入数据时，数据首先被压缩之后才写入磁盘。
S：Secure Delete，让系统在删除这个文件时，使用0填充文件所在的区域。
u：Undelete，当一个应用程序请求删除这个文件，系统会保留其数据块以便以后能够恢复删除这个文件。
12.枚举一个目录中的所有文件夹
#!/bin/bash
OLDIFS=$IFS
IFS=:
for path in $( find "%%1" -type d -printf "%p$IFS")
do
#"$path"
done
IFS=$OLDIFS
13.复制文件夹
#!/bin/sh
cp -rf "%%1" "%%2"

if [ -d $dir2cp ]; then
cp $dir2cp "%%2"
fi
done
15.移动文件夹
#!/bin/sh
mv -rf "%%1" "%%2"
16.移动一个目录下所有的文件夹到另一个目录下
#!/bin/bash
direc="%%1" #$(pwd)
for dir2mv in $direc/* ; do
if [ -d $dir2mv ]; then

direc="%%1" #$(pwd)
OLDIFS=$IFS
IFS=:
for path in $( find $direc -type d -printf "%p$IFS")
do
mkdir -p "%%2/${path:${#direc}+1}"
done
IFS=$OLDIFS
#cp -a "%%1" "%%2"
表达式 含义
${#string}
{#string}
1，取得字符串长度
string=abc12342341 //等号二边不要有空格
echo ${#string} //结果11
expr length $string //结果11
expr "$string" : ".*" //结果11 分号二边要有空格,这里的:根match的用法差不多2，字符串所在位置
expr index $string '123' //结果4 字符串对应的下标是从0开始的这个方法让我想起来了js的indexOf，各种语言对字符串的操作方法大方向都差不多，如果有语言基础的话，学习shell会很快的。
3，从字符串开头到子串的最大长度
expr match $string 'abc.*3' //结果9个人觉得这个函数的用处不大，为什么要从开头开始呢。
4，字符串截取
echo ${string:4} //2342341 从第4位开始截取后面所有字符串
echo ${string:3:3} //123 从第3位开始截取后面3位
echo ${string:3:6} //123423 从第3位开始截取后面6位
echo ${string: -4} //2341 ：右边有空格 截取后4位
echo ${string:(-4)} //2341 同上
expr substr $string 3 3 //123 从第3位开始截取后面3位上面的方法让我想起了，php的substr函数，后面截取的规则是一样的。
5，匹配显示内容
//例3中也有match和这里的match不同，上面显示的是匹配字符的长度，而下面的是匹配的内容
expr match $string '([a-c]*[0-9]*)' //abc12342341
expr $string : '([a-c]*[0-9])' //abc1
expr $string : '.*([0-9][0-9][0-9])' //341 显示括号中匹配的内容这里括号的用法，是不是根其他的括号用法有相似之处呢，
6，截取不匹配的内容
echo ${string#a*3} //42341 从$string左边开始，去掉最短匹配子串
echo ${string#c*3} //abc12342341 这样什么也没有匹配到
echo ${string#*c1*3} //42341 从$string左边开始，去掉最短匹配子串
echo ${string##a*3} //41 从$string左边开始，去掉最长匹配子串
echo ${string%3*1} //abc12342 从$string右边开始，去掉最短匹配子串
echo ${string%%3*1} //abc12 从$string右边开始，去掉最长匹配子串这里要注意，必须从字符串的第一个字符开始，或者从最后一个开始，
7，匹配并且替换
echo ${string/23/bb} //abc1bb42341 替换一次
echo ${string//23/bb} //abc1bb4bb41 双斜杠替换所有匹配
echo ${string/#abc/bb} //bb12342341 #以什么开头来匹配，根php中的^有点像
echo ${string/%41/bb} //abc123423bb %以什么结尾来匹配，根php中的$有点像

37.读取XML数据库
如何通过shell命令行读取xml文件中某个属性所对应的值？
例如：
<key>BuildVersion</key> <string>5</string>
我希望能够通过Unix shell命令对属性键的名称BuildVersion进行查询，返回的结果是5，如何实现呀？
#!/bin/bash
grep BuildVersion|sed 's/.*<.*>([^<].*)<.*>.*/1/'
结果返回的是“BuildVersion”，而不是“5”，如果要查询BuildVersion自动返回数值5应当如何写？
应该没错的。试一下： echo "<key>BuildVersion</key> <string>5</string>"|grep BuildVersion|sed 's/.*<.*>([^<].*)<.*>.*/1/'我在SL的终端里试，返回值是5
目前需要从xml文件提取数据，想做一个xmlparser.sh
xml 类似这样
<result>
<shareinfo hostip="192.168.0.1" sharename="abcd" password="abc123"></shareinfo>
</result>
希望输入 xmlparser.sh a.xml hostip可以返回192.168.0.1
#!/bin/sh
if [ $# -ne 2 ];then
echo "Usage: $0 <xmlfile> <key>"
exit 0
fi
grep $2 $1|awk '{print $2}'|grep -o "[0-9.]*"
把
grep $2 $1|awk '{print $2}'|grep -o "[0-9.]*"
改成
grep $2 $1|awk '{print $2}'|grep -Eo "[0-9.]+"
楼上这个有问题，如果我要得到的是
<result>
<shareinfo hostip="192.168.0.1" sharename="abcd" password="abc123"></shareinfo>
</result>
中的sharename，那么，呵呵，就错了
我觉得应该先定位到第二个参数“$2”的位置，然后再提取“=”后面的内容
这里有个完整的实现：
Parse Simple XML Files using Bash – Extract Name Value Pairs and Attributes
http://www.humbug.in/2010/parse-simple-xml-files-using-bash-extract-name-value-pairs-and-attributes/
不过需要安装xmllint.
设计到对多个xml文件进行element的读取和列表。有人做过么？
举个例子，
多个xml文件里面都有
<article>
<title>xxx</titlel>
</article>
通过shell读取，然后合并到一起，再生成一个新的xml，但是其他元素不变。
<article>
<title>aaa</titlel>
</article>
<article>
<title>bbb</titlel>
</article>
如果格式异常简单，没有特例，那么可以用shell实现
如果有可能格式复杂，因为shell的命令所使用的正则表达式都不支持跨行匹配，所以用shell来解决这个问题就绕圈子了。
用perl来作这个工作最直接、简单。perl的XML:DOM模块是专门处理XML文件的。
偶倒是觉得,用PHP写Scripts也很方便,功能强大,而且,跨平台,
#!/bin/sh
sed -n '/<article>/{
N;
/
[[:space:]]*<title>/{
N;
/<article>.*</article>/p
}
D;
n
}'
这小段代码能把一个xml文件中,你要的东西拿出来.
你可以用for file in $*把这些信息都>>tmpfile中.
然后用sed 在指定文件的指定位置用r命令把tmpfile粘贴进来~~~~
大思路如此^_^ 我想有这个东西(只要能正确的跑出结果)后面就不难了吧...
Name
xmllint — command line XML tool
Synopsis
xmllint [[--version] | [--debug] | [--shell] | [--debugent] | [--copy] | [--recover] | [--noent] | [--noout] | [--nonet] | [--htmlout] | [--nowrap] | [--valid] | [--postvalid] | [--dtdvalid URL] | [--dtdvalidfpi FPI] | [--timing] | [--output file] | [--repeat] | [--insert] | [--compress] | [--html] | [--xmlout] | [--push] | [--memory] | [--maxmem nbbytes] | [--nowarning] | [--noblanks] | [--nocdata] | [--format] | [--encode encoding] | [--dropdtd] | [--nsclean] | [--testIO] | [--catalogs] | [--nocatalogs] | [--auto] | [--xinclude] | [--noxincludenode] | [--loaddtd] | [--dtdattr] | [--stream] | [--walker] | [--pattern patternvalue] | [--chkregister] | [--relaxng] | [--schema] | [--c14n]] [xmlfile]
Introduction
The xmllint program parses one or more XML files, specified on the command line as xmlfile. It prints various types of output, depending upon the options selected. It is useful for detecting errors both in XML code and in the XML parser itself.
It is included in libxml2.
Options
--version
Display the version of libxml2 used.
--debug
Parse a file and output an annotated tree of the in-memory version of the document.
--shell
Run a navigating shell. Details on available commands in shell mode are below.
--debugent
Debug the entities defined in the document.
--copy
Test the internal copy implementation.
--recover
Output any parsable portions of an invalid document.
--noent
Substitute entity values for entity references. By default, xmllint leaves entity references in place.
--nocdata
Substitute CDATA section by equivalent text nodes.
--nsclean
Remove redundant namespace declarations.
--noout
Suppress output. By default, xmllint outputs the result tree.
--htmlout
Output results as an HTML file. This causes xmllint to output the necessary HTML tags surrounding the result tree output so the results can be displayed in a browser.
--nowrap
Do not output HTML doc wrapper.
--valid
Determine if the document is a valid instance of the included Document Type Definition (DTD). A DTD to be validated against also can be specified at the command line using the --dtdvalid option. By default, xmllint also checks to determine if the document is well-formed.
--postvalid
Validate after parsing is completed.
--dtdvalid URL
Use the DTD specified by URL for validation.
--dtdvalidfpi FPI
Use the DTD specified by the Public Identifier FPI for validation, note that this will require a Catalog exporting that Public Identifier to work.
--timing
Output information about the time it takes xmllint to perform the various steps.
--output file
Define a file path where xmllint will save the result of parsing. Usually the programs build a tree and save it on stdout, with this option the result XML instance will be saved onto a file.
--repeat
Repeat 100 times, for timing or profiling.
--insert
Test for valid insertions.
--compress
Turn on gzip compression of output.
--html
Use the HTML parser.
--xmlout
Used in conjunction with --html. Usually when HTML is parsed the document is saved with the HTML serializer, but with this option the resulting document is saved with the XML serializer. This is primarily used to generate XHTML from HTML input.
--push
Use the push mode of the parser.
--memory
Parse from memory.
--maxmem nnbytes
Test the parser memory support. nnbytes is the maximum number of bytes the library is allowed to allocate. This can also be used to make sure batch processing of XML files will not exhaust the virtual memory of the server running them.
--nowarning
Do not emit warnings from the parser and/or validator.
--noblanks
Drop ignorable blank spaces.
--format
Reformat and reindent the output. The $XMLLINT_INDENT environment variable controls the indentation (default value is two spaces " ").
--testIO
Test user input/output support.
--encode encoding
Output in the given encoding.
--catalogs
Use the catalogs from $SGML_CATALOG_FILES. Otherwise /etc/xml/catalog is used by default.
--nocatalogs
Do not use any catalogs.
--auto
Generate a small document for testing purposes.
--xinclude
Do XInclude processing.
--noxincludenode
Do XInclude processing but do not generate XInclude start and end nodes.
--loaddtd
Fetch external DTD.
--dtdattr
Fetch external DTD and populate the tree with inherited attributes.
--dropdtd
Remove DTD from output.
--stream
Use streaming API - useful when used in combination with --relaxng or --valid options for validation of files that are too large to be held in memory.
--walker
Test the walker module, which is a reader interface but for a document tree, instead of using the reader API on an unparsed document it works on a existing in-memory tree. Used in debugging.
--chkregister
Turn on node registration. Useful for developers testing libxml2 node tracking code.
--pattern patternvalue
Used to exercise the pattern recognition engine, which can be used with the reader interface to the parser. It allows to select some nodes in the document based on an XPath (subset) expression. Used for debugging.
--relaxng schema
Use RelaxNG file named schema for validation.
--schema schema
Use a W3C XML Schema file named schema for validation.
--c14n
Use the W3C XML Canonicalisation (C14N) to serialize the result of parsing to stdout. It keeps comments in the result.
Shell
xmllint offers an interactive shell mode invoked with the --shell command. Available commands in shell mode include:
base
display XML base of the node
bye
leave shell
cat node
Display node if given or current node.
cd path
Change the current node to path (if given and unique) or root if no argument given.
dir path
Dumps information about the node (namespace, attributes, content).
du path
Show the structure of the subtree under path or the current node.
exit
Leave the shell.
help
Show this help.
free
Display memory usage.
load name
Load a new document with the given name.
ls path
List contents of path (if given) or the current directory.
pwd
Display the path to the current node.
quit
Leave the shell.
save name
Saves the current document to name if given or to the original name.
validate
Check the document for error.
write name
Write the current node to the given filename.
Catalogs
Catalog behavior can be changed by redirecting queries to the user's own set of catalogs. This can be done by setting the XML_CATALOG_FILES environment variable to a list of catalogs. An empty one should deactivate loading the default /etc/xml/catalog default catalog.
Debugging Catalogs
Setting the environment variable XML_DEBUG_CATALOG using the command "export XML_DEBUG_CATALOG=" outputs debugging information related to catalog operations.
Error Return Codes
On the completion of execution, Xmllint returns the following error codes:
0
No error
1
Unclassified
2
Error in DTD
3
Validation error
4
Validation error
5
Error in schema compilation
6
Error writing output
7
Error in pattern (generated when [--pattern] option is used)
8
Error in Reader registration (generated when [--chkregister] option is used)
9
Out of memory error
Parse Simple XML Files using Bash – Extract Name Value Pairs and Attributes
2 Comments

Pratik Sinha | July 31, 2010
I have written up a simple routine par***ML to parse simple XML files to extract unique name values pairs and their attributes. The script extracts all xml tags of the format <abc arg1="hello">xyz</abc> and dynamically creates bash variables which hold values of the attributes as well as the elements. This is a good solution, if you don’t wish to use xpath for some simple xml files. However you will need xmllint installed on your system to use the script. Here’s a sample script which uses the par***ML function
#!/bin/bash
xmlFile=$1
function par***ML() {
elemList=( $(cat $xmlFile | tr '
' ' ' | XMLLINT_INDENT="" xmllint --format - | /bin/grep -e "</.*>$" | while read line; do
echo $line | sed -e 's/^.*<///' | cut -d '>' -f 1;
done) )
totalNoOfTags=${#elemList[@]}; ((totalNoOfTags--))
suffix=$(echo ${elemList[$totalNoOfTags]} | tr -d '</>')
suffix="${suffix}_"
for (( i = 0 ; i < ${#elemList[@]} ; i++ )); do
elem=${elemList[$i]}
elemLine=$(cat $xmlFile | tr '
' ' ' | XMLLINT_INDENT="" xmllint --format - | /bin/grep "</$elem>")
echo $elemLine | grep -e "^</[^ ]*>$" 1>/dev/null 2>&1
if [ "0" = "$?" ]; then
continue
fi
elemVal=$(echo $elemLine | tr ' 11' ' 40'| sed -e 's/^[ ]*//' -e 's/^<.*>([^<].*)<.*>$/1/' | sed -e 's/^[ ]*//' | sed -e 's/[ ]*$//')
xmlElem="${suffix}$(echo $elem | sed 's/-/_/g')"
eval ${xmlElem}=`echo -ne ""${elemVal}""`
attrList=($(cat $xmlFile | tr '
' ' ' | XMLLINT_INDENT="" xmllint --format - | /bin/grep "</$elem>" | tr ' 11' ' 40' | sed -e 's/^[ ]*//' | cut -d '>' -f 1 | sed -e 's/^<[^ ]*//' | tr "'" '"' | tr '"' '
' | tr '=' '
' | sed -e 's/^[ ]*//' | sed '/^$/d' | tr ' 11' ' 40' | tr ' ' '>'))
for (( j = 0 ; j < ${#attrList[@]} ; j++ )); do
attr=${attrList[$j]}
((j++))
attrVal=$(echo ${attrList[$j]} | tr '>' ' ')
attrName=`echo -ne ${xmlElem}_${attr}`
eval ${attrName}=`echo -ne ""${attrVal}""`
done
done
}
par***ML
echo "$status_xyz | $status_abc | $status_pqr" #Variables for each XML ELement
echo "$status_xyz_arg1 | $status_abc_arg2 | $status_pqr_arg3 | $status_pqr_arg4" #Variables for each XML Attribute
echo ""
#All the variables that were produced by the par***ML function
set | /bin/grep -e "^$suffix"
The XML File used for the above script example is:
<?xml version="1.0"?>
<status>
<xyz arg1="1"> a </xyz>
<abc arg2="2"> p </abc>
<pqr arg3="3" arg4="a phrase"> x </pqr>
</status>
The root tag, which in this case is “status”, is used as a suffix for all variables. Once the XML file is passed to the function, it dynamically creates the variables $status_xyz, $status_abc, $status_pqr, $status_xyz_arg1, $status_abc_arg2, $status_pqr_arg3 and $status_pqr_arg4.
The output when the script is ran with the xml file as an argument is
@$ bash par***ML.sh test.xml
a | p | x
1 | 2 | 3 | a phrase
status_abc=p
status_abc_arg2=2
status_pqr=x
status_pqr_arg3=3
status_pqr_arg4='a phrase'
status_xyz=a
status_xyz_arg1=1
This script won’t work for XML files like the one below with duplicate element names.
<?xml version="1.0"?>
<status>
<test arg1="1"> a </test>
<test arg2="2"> p </test>
<test arg3="3" arg4="a phrase"> x </test>
</status>
This script also won’t be able to extract attributes of elements without any CDATA. For eg, the script won’t be able to create variables corresponding to <test arg1="1">. It will only create the variables corresponding to <test1 arg2="2">abc</test1>.
<?xml version="1.0"?>
<status>
<test arg1="1">
<test1 arg2="2">abc</test1>
</test>
</status>

mysqladmin -u root -password 123456
3,修改root用户密码为 abc123
mysqladmin -u root -p123456 password abc123
4,如果想去掉密码：
mysqladmin -u root -pabc123 password ""
5,root连接数据库有密码和无密码：
mysql -u root(-uroot) -p
mysql
6,增加用户 test1 密码 abc,让它可以在任何主机上登录，并对所有数据库有查询，插入，修改，删除的权限：
格式： grant select on 数据库.* to 用户名@登录主机 identified by "密码"
grant select,insert,update,delete on *.* to test1@"%" Identified by "abc";
8,增加一个用户test2,让它只可以在localhost上登录，并可以对数据库mydb进行查询，插入，修改，删除的操作，
这样用户即使使用知道test2的密码，他也无法从internet 上直接访问数据库，只能通过mysql主机上的web页面来访问。
grant select,insert,update,delete on mydb.* to test2@localhost identified by "abc";
grant select,insert,update,delete on mydb.* to test2@localhost identified by ""; 设置无密码
9,显示数据库列表：
show databases;
use mysql 打开库
show tables;
10,表的操作
