Bug#265281: lintian: warns for possible bashism when using sed

[Jonas Meurer <jonas@freesources.org>]

Package: lintian
Version: 1.23.2
Severity: normal

hi,

lintian reports a possible bashism in the maintainer scripts where i use
sed to fetch the python version:

from pythonPV-mysqldb.postinst:

PV=`echo $PACKAGE | sed -n -e '/^python.*-/{s,python\([0-9][0-9.]*\)-.*,\1,p}'`

lintian reports:

W: python2.3-mysqldb: possible-bashism-in-maintainer-script postinst:8 
					'/{s,python\([0-9][0-9.]*\)-.*,\1,p}'
N:
N:   This script is marked as running under /bin/sh, but it seems to use a
N:   feature found in bash.
[...]

in my eyes there's no need for bash as the script is sed, and can be run
by any shell we provide in /etc/shells.

bye
 jonas
