Welcome to the ShellCheck wiki!

If you tried to follow a link for an issue but ended up here, it means that page does not exist yet :(

You can file an issue about it and ask that it be added.


ShellCheck is a static analysis tool for shell scripts. This wiki holds all the long form descriptions of warnings and suggestions it outputs. If you get this output:

$ shellcheck myscript
In myscript line 5:
eof
   ^-- SC1118: Delete whitespace after the here-doc end token.

and it's too terse or you're not sure whether it applies, you can read more on this wiki page: SC1118.

On ShellCheck.net, you can just click the error code to go to this page.

If you would like to contribute and create a page, just copy the Template and give it a name like SC1000, and bask in unending appreciation from shell scripters world wide!
