Can't get $(date +%F) set as environment variable












6















I would like to create an environment variable that will output the current date. I have added the following to ~/.pam_environment:



TODAY=$(date +%F)


Apparently, you have to log out after changing ~/.pam_environment. I did that but



echo $TODAY


outputs a blank line.



What am I doing wrong?

            You forgot the "quotes" Here is a Cool Link for more examples.



            TODAY= date +"%F"

            • Unfortunately that did not work. I tried experimenting a bit and added the following to ~/.pam_environment: TODAY=date +"%F" TODAYS=$(date +"%F") NOW=$(date +"%m-%d-%Y") None of these are working

              @ScottGoodgame That's not the problem. It is not generally necessary to quote %, and although the reference you provided follows this style, it does not actually say one has to do so. Try some examples from that page without quotes (e.g., date +%m-%d-%y). It works fine. In addition, TODAY= date +"%F" actually runs date +"%F" with TODAY set to the empty string in its environment.
