Index / Unix


FreeBSD has two different shells in the base system. sh(1) is a Bourne type POSIX compatible shell and the default for new users. tcsh(1) on the other hand is an advanced version of the C shell and the default for the root user.

I use sh for both scripting and interactive use. Here follow some tips and tricks that I have found useful.

Color File Listings

This is actually a feature of ls(1). Color listings can be permanently enabled by setting the environment variable CLICOLOR, the actual colors used can be defined with the environment variable LSCOLORS.

Here is what I have in my .profile:

export CLICOLOR="1"
# ls(1) attr.key:1122334455667788990011
export LSCOLORS="Exfxcxdxbxegedabagacad"
