如何使用变量作为查找命令的路径 [英] How to use variable as a path for find command
本文介绍了如何使用变量作为查找命令的路径的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
可以有人给我一个提示,我可以如何使下面的bash脚本正常运行:
path =/ path /
excludepath =!-path \/ path / to / exclude / * \
找到$ path$ excludepath-name *。txt -type f
当我尝试运行它时,我得到:
find:`! -path/ path / to / exclude / *':没有这样的文件或目录
谢谢您的问题是事实上,$ excludepath
>是一个参数,即使它包含空格。要放置几个参数,请使用字符串数组而不是字符串:
excludepath =(!-path* webshow * )
找到$ path$ {excludepath [@]}-name* .txt-type f
这是一个bashism,但是(绊倒这个的人不要使用 bash
将需要做其他事情)
Can someone give me a hint, how I can make the following bash script run properly:
path="/path/"
excludepath="! -path \"/path/to/exclude/*\" "
find "$path" "$excludepath" -name *."txt" -type f
When I try to run it I get:
find: `! -path "/path/to/exclude/*"': No such file or directory
Thank you in advance.
解决方案
Your problem was the fact that "$excludepath"
is a single argument, even if it contains spaces. To put several arguments, use an array of strings instead of a string:
excludepath=(! -path "*webshow*")
find "$path" "${excludepath[@]}" -name "*.txt" -type f
This is a bashism, though (people that stumble onto this and don't use bash
will need to do something else).
