Listing environment variables (env command)

Edit online

To display your current environment variables, use the env command. An environment variable that is accessible to all your processes is called a global variable.

For example, to list all environment variables and their associated values, type the following:

env

The following is an example of the output:

TMPDIR=/usr/tmp
myid=denise
LANG=En_US
UNAME=barnard
PAGER=/bin/pg
VISUAL=vi
PATH=/usr/ucb:/usr/lpp/X11/bin:/bin:/usr/bin:/etc:/u/denise:/u/denise/bin:/u/bin1
MAILPATH=/usr/mail/denise?denise has mail !!!
MAILRECORD=/u/denise/.Outmail
EXINIT=set beautify noflash nomesg report=1 showmode showmatch
EDITOR=vi
PSCH=>

LOGNAME=denise

HISTSIZE=500

FCEDIT=vi

ENV=/u/denise/.env

If the listing is very long, the top portion scrolls off the screen. To display the listing one page (screen) at a time, use the env command piped to the pg command. At the prompt, type the following:

env | pg
