A quick guide to the printenv
command, used to print the values of environment variables
In any shell there are a good number of environment variables, set either by the system, or by your own shell scripts and configuration.
You can print them all to the terminal using the printenv
command. The output will be something like this:
HOME=/Users/flavio
LOGNAME=flavio
PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin
PWD=/Users/flavio
SHELL=/usr/local/bin/fish
with a few more lines, usually.
You can append a variable name as a parameter, to only show that variable value:
printenv PATH
The printenv
command works on Linux, macOS, WSL, and anywhere you have a UNIX environment
