makewhatis

So that took longer than it should. There is a command called whatis that gives you a single line description of a command:



whatis grep


grep (1) - print lines matching a pattern
grep (1p) - search a file for a pattern
grep (rpm) - The GNU versions of grep pattern matching utilities



A nice little tool to use. I just installed CentOS 5 in a VM and noticed that all my whatis commands were returning nothing appopriate…I quickly found the makewhatis command on some articles but could not locate it for CentOS 5 at first. Finally found the location:


/usr/sbin/makewhatis



This command builds the database and now my whatis commands are working.
