Check those shell scripts online!

[Habitual]

[url=http://www.shellcheck.net/]Shellcheck[/url] is a static analysis and linting tool for sh/bash scripts. It's mainly focused on handling typical beginner and intermediate level syntax errors and pitfalls where the shell just gives a cryptic error message or strange behavior, but it also reports on a few more advanced issues where corner cases can cause delayed failures.

Visual feedback on common scripting errors and syntax issues.
It's a Keeper!

Enjoy.

Great site, gonna use it when in trouble scripting something

[Habitual]

It is, but NOTE:
It likes to 'suggest' escaping some $(sub-shell) processes with "Quote this to prevent word splitting."

for example:

Code: Select all

ec2-copy-image -r us-east-1 --region us-west-2 -s $( awk 'NR==1 {print $2}' "$lst" ) -n "$td" -d "Daily ${suffix} backup" # 'bad substitution' "error" using ${suffix^}

but still, it's a Winner.

TBH, I'm not certain. I think I grokked it over at Ubuntuforums.org tooling around like I do, looking "under the hood" for challenges/solutions, you know
