I haven't seen this before. I use env which is similar to printenv

unix.stackexchange.com/questions/1...

View variables.

env
Enter fullscreen mode Exit fullscreen mode

And to search:

env | grep PATH
Enter fullscreen mode Exit fullscreen mode

Or just

echo $PATH
Enter fullscreen mode Exit fullscreen mode

I see you cover env in the next post for modifying environment but not for reading it

Hey, yes actually you can grep the output of the env and get the values or echo works as well. Most the people use what you have mentioned above and very few people are aware about printenv and how easy it is to use. That's the only reason wrote about it. Thanks for the feedback on the env blog, I will surely consinder adding more about reading a varibale.

printenv FOO is longer to type than echo $FOO and also it is less flexible. You can't do something like echo "$FOO $BAR"

Maybe you can make an alias:

alias p=printenv
Enter fullscreen mode Exit fullscreen mode

So you can run

p FOO
Enter fullscreen mode Exit fullscreen mode
