Suppose you want a group, say gid=10 which is staff, using POSIX compliant id:

Code:
[ `id -g` -eq 10 ] && M_ROOT=/usr/local/bin/m_prog
[ "`id -gn`" = "staff"  ] && M_ROOT=/usr/local/bin/m_prog

The id command was meant for this kind of thing

DH_USRLOCAL(1)							     Debhelper							    DH_USRLOCAL(1)

NAME
dh_usrlocal - migrate usr/local directories to maintainer scripts SYNOPSIS
dh_usrlocal [debhelperoptions] [-n] DESCRIPTION
dh_usrlocal is a debhelper program that can be used for building packages that will provide a subdirectory in /usr/local when installed. It finds subdirectories of usr/local in the package build directory, and removes them, replacing them with maintainer script snippets (unless -n is used) to create the directories at install time, and remove them when the package is removed, in a manner compliant with Debian policy. These snippets are inserted into the maintainer scripts by dh_installdeb. See dh_installdeb(1) for an explanation of debhelper maintainer script snippets. When the Rules-Requires-Root field is not (effectively) binary-targets, the directories in /usr/local will have ownership root:staff and the mode will be 02775. These values have been chosen to comply with the recommendations of the Debian policy for directories in /usr/local. When Rules-Requires-Root has an effective value of binary-targets, the owners, groups and permissions will be preserved with one exception. If the directory is owned by root:root, then ownership will be reset to root:staff and mode will be reset to 02775. This is useful, since that is the group and mode policy recommends for directories in /usr/local. OPTIONS
-n, --no-scripts Do not modify postinst/prerm scripts. NOTES
Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to maintainer scripts. CONFORMS TO
Debian policy, version 2.2 SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
