问题描述
我试图将 awk命令(命令，而不是结果)存储在变量中.我的目标是稍后在脚本中以不同的输入使用该变量.例如:
I'm trying to store an awk command (command, not the result) in a variable. My objective is to use that variable later in the script, with different inputs. For example:
cmd=$(awk '/something/ {if ...} {...} END {...}')
$cmd $input
我尝试将命令存储为$()(如示例中)，也存储为backticks ...但是我无法实现.
I've tried to store the command with $() (like in the example), also with backticks ... But I'm not able to achieve it.
我感谢您的帮助或任何建议:)
I appreciate the help or any suggestion :)
推荐答案
忘记引号和括号.您只想存储awk脚本本身
Forget the backticks and parentheses. You just want to store the awk script itself
cmd='/something/ {if ...} {...} END {...}'
awk "$cmd" $input
