将命令输出的结果给一个循环处理,常用的方式如下:
[root@etch171 guosong]# ls |while read line;do echo $line;done processlist top
使用EOF处理:
[root@etch171 guosong]# while read line ;do echo $line;done<<EOF > `ls .` > EOF processlist top [root@etch171 guosong]# ls . processlist top
对应的需求是啥?将多行处理的结果传递给循环
#!/bin/sh mysql -uroot -p123456 <<EOF use test; select * from testaa while a=10000; ###1000 not usr single quote mark,because a is int # type,only char type need single quote mark. exit EOF
