If you have locate installed, here's a handy little command to generate a MANPATH statement for you:
Code:
echo -n export MANPATH=\" ; locate -r '/man$' | while read d; do [ -d "$d" ] && echo -n $d:; done ; echo \"
You can copy-paste the output of that command to your .bashrc or .profile or whatever is appropriate for your shell, and then when you next log in you will have the MANPATH set automatically.
