'[' is an alias for 'test' and is only used by some shells that don't have them set as builtin. They *might* be useful for some boot scripts, even though we don't use them. basename and touch fall into the same category. A quick check of a RH9 system shows [, install, and test in /usr/bin; touch and basename are in /bin.

[ is a symlink to test and should also be in /usr/bin. I see no reason why install should not be in /usr/bin. basename could be used, for instance, in customization script for dhcp and touch could be used for file locking. For these reasons, I'd put these in /bin. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
