man checkbash (Commandes) - Check for bashisms in maintainer scripts

NAME

checkbash - Check for bashisms in maintainer scripts

SYNOPSIS

checkbash script

DESCRIPTION

checkbash is a script used by debstd to check maintainer scripts for bashisms.

debstd runs checkbash on files (preinst, postinst, prerm and postrm) starting with #!/bin/sh.

When a bashism is detected, checkbash prints a message and quits. Thus, only the first bashism is printed.

checkbash checks for the following bashisms:

'{.*,.*}'
If { and } are used
'[[:space:]]~'
If ~ Tilde Expansion is used
'&>'
If special Redirection Symbol &> is used
'select'
If the select Statement is used

RETURN VALUE

If no bashisms were found, checkbash quits with 0. If bashisms were found, it quits with 1.
