检查Bash中的字符串包含斜杠还是反斜杠? [英] Check if string containts slash or backslash in Bash?

问题描述

我当前正在尝试获取bash脚本，以检查字符串是否包含"/" 或"\"

I'm currently trying to get my bash script checking if a string containts a "/" or a "\" but somehow I can't get it working.

这是我到目前为止所得到的:

Here is what I got so far:

if [[ "$1" == *\/* ]]; then
   ...
elif if [[ "$1" == *\\* ]]; then
   ...
fi

非常感谢您的帮助！谢谢

Help is much appreciated! Thanks

推荐答案

这将检查 \ 或/是否在变量 $ string .

This checks if either \ or / are in the variable $string.

if [[ "$string" == *\/* ]] || [[ "$string" == *\\* ]]
then
  echo "yes"
fi

测试:

$ string="hello"
$ if [[ "$string" == *\/* ]] || [[ "$string" == *\\* ]]; then echo "yes"; fi
$
$ string="hel\lo"
$ if [[ "$string" == *\/* ]] || [[ "$string" == *\\* ]]; then echo "yes"; fi
yes
$ string="hel//lo"
$ if [[ "$string" == *\/* ]] || [[ "$string" == *\\* ]]; then echo "yes"; fi
yes
