unix - 命令作为参数传递给 shell 脚本

Question

我想将命令传递给 shell 脚本。此命令是 grep 命令。执行时出现以下错误，请帮忙:

myscript.sh "egrep 'ERROR|FATAL' \*20100428\*.log | grep -v aString"

myscript.sh 是一个简单的脚本:

#!/bin/ksh

cd log

$1

错误是:

egrep: can't open |
egrep: can't open grep
egrep: can't open -v
egrep: can't open aString

错误是因为 egrap 将 |、grep、-v 和 aString 视为参数。

尝试这个:

eval $1
