Is it possible to check a bash script syntax without executing it?
Using Perl, I can run
perl -c 'script name'. Is there any equivalent command for bash scripts?
bash -n scriptname
Perhaps an obvious caveat: this validates syntax but won't check if your bash script tries to execute a command that isn't in your path, like
ech hello instead of
Time changes everything. Here is a web site which provide online syntax checking for shell script.
I found it is very powerful detecting common errors.
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.
