[英]Fish Shell: validate if string contains substring
Currently I'm trying to validate if my string which contains a path contains a specific string. 目前,我正在尝试验证包含路径的字符串是否包含特定字符串。
I've already tried the bash comparison: 我已经尝试过bash比较:
and 和
I also try the 'contains' keyword. 我也尝试使用“包含”关键字。 But i'm not sure if I'm suppose to use this with a string.. 但是我不确定是否应该将它与字符串一起使用。
Unfortunately these attempts all failed. 不幸的是,这些尝试都失败了。 :/ :/
function next_dir
set foundcwd 0
set cwd $PWD
set error 'There is no next directory to navigate to...'
if [ -z $cwd ]
echo $error
else
echo $cwd
for d in ../*/
set needle (string split "/" -- $d)[2]
if [ $foundcwd = 1 ]
cd $d
break
end
if [ $cwd =~ $needle ]
$foundcwd = 1
end
end
end
end
The goal of my function is to navigate to the next (sibling) directory. 我函数的目标是导航到下一个(同级)目录。
/mnt/c/workingdirectory/repoA --> current directory /mnt/c/workingdirectory/repoB --> navigate to repoB / mnt / c / workingdirectory / repoA->当前目录/ mnt / c / workingdirectory / repoB->导航到repoB
您想要string match
。
if string match -q -- $needle $path
