    tar

    经常用tar命令,也知道其几个参数,单总缺乏系统的了解。大概看了一下GNU tar的手册http://www.gnu.org/software/tar/manual/tar.html#SEC28,没有对每个命令和参数都详加了解和实验。大概了解到tar的命令和参数很多,写法也多种多样,感觉只有你想不到,没有tar做不到。GUN软件作者的精神真是让人感动。以下列出最常用的,对某一功能有新的需求时再详细学习。

    operations

    Exactly one of eight operations is both allowed and required for any instance of using tar. Users may not specify more than one operation.

    The Frequently Used Operations

    --create
    -c
    Create a new tar archive.
    --list
    -t
    List the contents of an archive.
    $ tar --list --file=bfiles.tar --wildcards '*b*'
    
    --extract
    -x
      Extract one or more members from an archive.
    --delete
       Deletes members from the archive.
    --update
    -u
    Adds files to the end of the archive, but only if they are newer than their counterparts already in the archive, or if they do not already exist in the archive.

    Two Frequently Used Options

    --file=archive-name
    -f archive-name
      Specify the name of an archive file.
    --verbose
    -v
      Show the files being worked on as tar is running.
    --bzip2
    -j
    This option tells tar to read or write archives through bzip2.
    --absolute-names
    -P
    Normally when creating an archive, tarstrips an initial ‘/
    ’ from member names. This option disables that behavior.
    --gzip
    --gunzip
    --ungzip
    -z
    This option tells tar to read or write archives through gzip, allowing tar to directly operate on several kinds of compressed archives transparently.
