Bug#486030: fbb: bashism in /bin/sh script

Package: fbb
Severity: important
Version: 7.04j-7
User: debian-release@...
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/sbin/fbb line 244 ('$[' should be '$(('):
>                 NB=$[ $NB + 1 ]
> possible bashism in ./usr/sbin/fbb line 272 ('$[' should be '$(('):
>                                 NUMPORT=$[ $NUMPORT + 1 ]
> possible bashism in ./usr/sbin/fbb line 280 ('$[' should be '$(('):
>                                 NB=$[ $NB + 1 ]
> possible bashism in ./usr/sbin/fbb line 310 ('$[' should be '$(('):
>                         NB=$[ $NB + 1 ]

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:
