ShellCheck 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.
sample
$ shellcheck new
In new line 14:
read title
^-- SC2162: read without -r will mangle backslashes.
In new line 17:
read title
^-- SC2162: read without -r will mangle backslashes.
In new line 23:
if [ -f $file ]; then
^-- SC2086: Double quote to prevent globbing and word splitting.
