Personal, but valid. To test that you actually don't introduce bashisms
in a script you can simply set env variable POSIXLY_CORRECT=1 and then
the bash when invoked as /bin/sh will behave as a strict posix shell.


Unfortunately that doesn't work well enough- Even with POSIXLY_CORRECT=1 some bashisms work without 
any warning message. Yeah, so one kinda is left wondering what the point with POSIXLY_CORRECT is 
then.

I found this useful script: 
http://ftp.openbsd.org/ports/sysutils/checkbashisms/files/checkbashisms.pl . No doubt there might 
be other similar ones. 

Another way is to actually develop a script using a #! line referring to some suitably limited 
shell on your platform, and then change that to /bin/sh  before submitting as a patch or committing 
to git.
