\subsection contains-description Description
|
|
|
|
`contains` tests whether the set `VALUES` contains the string `KEY`. If so, `contains` exits with status 0; if not, it exits with status 1.
|
|
|
|
The following options are available:
|
|
|
|
- `-i` or `--index` print the word index
|
|
|
|
|
|
\subsection contains-example Example
|
|
|
|
\fish
|
|
for i in ~/bin /usr/local/bin
|
|
if not contains $i $PATH
|
|
set PATH $PATH $i
|
|
end
|
|
end
|
|
\endfish
|
|
|
|
The above code tests if `~/bin` and `/usr/local/bin` are in the path and adds them if not.
