Bug#530126: live-helper: bashism in /bin/sh script
Package: live-helper
Severity: important
Version: 1.0.4-1
User: debian-release@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 a /bin/sh script making use
of a bashism.
checkbashisms' output:
> possible bashism in ./etc/cron.daily/live-helper line 38
> ($HOST(TYPE|NAME)):
> echo "$(date +%b\ %d\ %H:%M:%S) ${HOSTNAME} live-helper: begin daily
> build." >> /var/log/live
> possible bashism in ./etc/cron.daily/live-helper line 154
> ($HOST(TYPE|NAME)):
> echo "$(date +%b\ %d\ %H:%M:%S) ${HOSTNAME} live-helper: end daily build."
> >> /var/log/live
Not using bash (or a Debian Policy conformant shell interpreter which doesn't
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 was
a release goal for Lenny to make dash the default /bin/sh[1], and has been
proposed for squeeze as well[2].
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 supporting this goal please refer to Debian Policy,
section 10.4, 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.
If not already fixed you can read:
https://wiki.ubuntu.com/DashAsBinSh
If you still don't know how to fix the bashisms don't hesitate to reply to
this email, or tag the bug as 'help'.
