I have a long shell script containing a lot of conditions and I want to know whether there is any syntax error in the script without running it.

Since shell script is interpreted I think it is not possible but is there a way to know by using some trick.

bash -n scriptname

Although, this will check syntax, not command availability. (will not warn if script uses a command that is not installed yet)

    In addition to bash's inbuilt syntax checḱing you can use shellcheck to identify less severe issues and bad practices. – Glutanimate Jun 15 '14 at 22:40

I found an online tool to check the syntax of the script. In addition to checking the script, also suggests possible corrections to avoid errors.
