[DebianGIS-dev] Bug#489603: gpsdrive: bashism in /bin/sh script

[Raphael Geissert]

Package: gpsdrive
Severity: important
Version: 2.10~pre4-3
User: debian-release at lists.debian.org
Usertags: goal-dash

Hello maintainer,

While performing an archive wide checkbashisms (from the 'devscripts' package) 
check I've found your package containing one or more /bin/sh scripts making 
use of bashisms.

checkbashisms' output:
> possible bashism in ./usr/share/doc/gpsdrive/examples/wpget line 35
> (alternative test command ([[ foo ]] should be [ foo ])):
> if [[ ${#opt} != "3" && ${#opt} != "12" ]]; then

Not using bash (or a Debian Policy conformant shell interpreter which does 
provide such an extra feature) as /bin/sh is likely to lead to errors or 
unexpected behaviours.
Please be aware that although bash is currently the default /bin/sh there's a 
release goal for Lenny to make dash the default /bin/sh[1].

If you want more information about dash as /bin/sh, you can read:
http://lists.debian.org/debian-release/2008/01/msg00189.html

For more information please refer to the Debian Policy section 10.4 supporting 
this argument at:
http://www.debian.org/doc/debian-policy/ch-files.html#s-scripts

Hints about how to fix bashisms:
Sometimes these bugs are already fixed in Ubuntu, look at the PTS.
