Bug#489567: dpkg-cross: bashism in /bin/sh script
Package: dpkg-cross
Severity: important
Version: 2.2.4
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 one or more /bin/sh scripts making
use of bashisms.
checkbashisms' output:

> echo -e "\n-- dpkg-cross2.log --\n" >&3
> possible bashism in ./usr/share/bug/dpkg-cross/script line 20 (echo -e):

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.
If not already fixed you can read:
