mailsync (4129B)

      3 # - Syncs mail for all accounts, or a single account given as an argument.
      4 # - Displays a notification showing the number of new mails.
      5 # - Displays a notification for each new mail with its subject displayed.
      6 # - Runs notmuch to index new mail.
      7 # - This script can be set up as a cron job for automated mail syncing.
      8 
      9 # There are many arbitrary and ugly features in this script because it is
     10 # inherently difficult to pass environmental variables to cronjobs and other
     11 # issues. It also should at least be compatible with Linux (and maybe BSD) with
     12 # Xorg and MacOS as well.

     14 # Run only if not already running in other instance
     15 pgrep mbsync >/dev/null && { echo "mbsync is already running."; exit ;}

     17 # First, we have to get the right variables for the mbsync file, the pass
     18 # archive, notmuch and the GPG home.  This is done by searching common profile
     19 # files for variable assignments. This is ugly, but there are few options that
     20 # will work on the maximum number of machines.
