Help by adding links to BashFAQ, StackOverflow, man pages, POSIX, etc
Well, it's not clear how to actually add such a link. I guess you're
supposed to do it through github or something?
Thank you, Greg. I edited
https://github.com/koalaman/shellcheck/wiki/SC3026 (the link below the
page header) and the shellcheck.net page was updated in several hours.
Sorry, web interface assumes brief commit message, so I did not added
credits to you there.
I think, shellcheck is not known well enough while it may help to avoid
a lot of troubles with shell scripts. It can provide some hints when
unexpected behavior is observed and prevent it if used regularly.
As to [^c] vs. [!c], unfortunately the latter can not be always used as
portable variant. It is treated as history expansion in the case of
interactive bash session. From my point of view it is an argument to
support [^c]. The enhancement request was rejected however, see
Stephane Chazelas. Re: [v2 PATCH] expand: Always quote caret when using
