Menampilkan Setting Environment pada FreeBSD

Tuliskan perintah berikut ini:

router# env
USER=root
LOGNAME=root
HOME=/root
MAIL=/var/mail/root
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin:/root/bin
TERM=xterm
BLOCKSIZE=K
FTP_PASSIVE_MODE=YES
SHELL=/bin/csh
SSH_CLIENT=192.168.1.8 2155 22
SSH_CONNECTION=192.168.1.8 2155 192.168.1.1 22
SSH_TTY=/dev/ttyp0
HOSTTYPE=FreeBSD
VENDOR=intel
OSTYPE=FreeBSD
MACHTYPE=i386
SHLVL=1
PWD=/root
GROUP=wheel
HOST=router.klik.net
REMOTEHOST=192.168.1.8
EDITOR=vi
PAGER=more

Membuat variabel environment baru


sederhana saja, gunakan perintah:

# set X = 5
# set vech=Car
# set path = (/sbin /bin /usr/sbin /usr/bin /usr/games /usr/local/sbin /usr/local/bin $HOME/bin)

Atau anda dapat menggunakan perintah setenv:

# setenv EDITOR nano
# setenv PAGER less

File .cshsrc


Anda dapat memsaukkan semua variabel ke dalam file ~/.chsrc
dimana akan dibaca pada saat memulai eksekusi sheel tsb.
# nano ~/.cshrc

Contoh file:
router# cat ~/.cshrc
# $FreeBSD: src/etc/root/dot.cshrc,v 1.29 2004/04/01 19:28:00 krion Exp $
#
# .cshrc - csh resource script, read at beginning of execution by each shell
#
# see also csh(1), environ(7).
#

alias h history 25
alias j jobs -l
alias la ls -a
alias lf ls -FA
alias ll ls -lA

# A righteous umask
umask 22

set path = (/sbin /bin /usr/sbin /usr/bin /usr/games /usr/local/sbin /usr/local/bin /usr/X11R6/bin $HOME/bin)

setenv EDITOR vi
setenv PAGER more
setenv BLOCKSIZE K

if ($?prompt) then
# An interactive shell -- set some stuff up
set prompt = "`/bin/hostname -s`# "
set filec
set history = 100
set savehist = 100
set mail = (/var/mail/$USER)
if ( $?tcsh ) then
bindkey "^W" backward-delete-word
bindkey -k up history-search-backward
bindkey -k down history-search-forward
endif
endif

Melihat nilai variabel dari environment

Gunakan perintah echo, lalu enter:
# echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/games:/usr/local/sbin:/usr/local/bin:/usr/X11R6/bin:/root/bin
# echo $X
