bashism in /bin/sh script in nagios/bin/

[Jan Wagner]

Running checkbashisms (https://anonscm.debian.org/cgit/collab-maint/devscripts.git/plain/scripts/checkbashisms.pl) against nagios/bin/* from the 1.1.5 release results into the following error.

Not using bash as /bin/sh is likely to lead to errors or unexpected behaviours. Please be aware that dash is the default /bin/sh in Debian (and Derivates) and maybe other Distributions.
