Checking your .sh script for Bashisms

[rbelk]

I posted a tutorial on my site about checking your .sh scripts for bashisms. Here's the link Bashisms. Test it out to see if it works for yourself, any comments are welcome.

If you script works properly at FreeBSD or Solaris /bin/sh you do not need any further tools to confirm that

The checkbashisms also sometimes reports false alarms:

~/DEVSCRIPTS/usr/bin$ [color="Blue"]./checkbashisms ~/scripts/vergallery.sh [/color]
possible bashism in ~/scripts/vergallery.sh line 265 ($SECONDS):
      RESOLUTION="${MINUTES}:${SECONDS}"

while this line is 100% POSIX sh compatible.
