I use multiple screens on my system, I'm using separate session for each branch I may be working on. Now I would like to set environment variables depending on screen name (I name screens by branch path). I've tried this in ~/.screenrc:

screen -t "ABC-1234" bash -ic 'OUTPUTROOT=/home/me/src/NextGen/branches/ABC-1234/bin'
screen -t "ABC-1234" bash -ic 'SVN_ROOT=/home/me/src/NextGen/branches/ABC-1234'
screen -t "DEF-5678" bash -ic 'OUTPUTROOT=/home/me/src/NextGen/branches/DEF-5678/bin'
screen -t "DEF-5678" bash -ic 'SVN_ROOT=/home/me/src/NextGen/branches/DEF-5678'

but it doesn't seem to work, the env variables do not get set if my screens are called "ABC-1234" or "DEF-5678" and I open a new window using Ctrl-a c ...

Just start your screens from a shellscript:

SVN_ROOT=/home/me/src/NextGen/branches/ABC-1234 OUTPUTROOT=$SVN_ROOT/bin screen -dm -t "ABC-1234"
SVN_ROOT=/home/me/src/NextGen/branches/DEF-5678 OUTPUTROOT=$SVN_ROOT/bin screen -dm -t "DEF-5678" 
  • but this will create 4 screen sessions which is not what I want/need. I need two sessions with both, OUTPUTROOT & SVN_ROOT set.

  • i unfortunately am not able to get it to work the way I want, that's why I've asked the question! I've tried multiple things including: OUTPUTROOT=/home/me/src/NextGen/branches/$1/bin;SVN_ROOT=/home/me/src/NextGen/branches/$1 screen -dm -S $1; but this does not seem to set OUTPUTROOT at all but only SVN_ROOT - $1 being the string I pass to my bash script with the name of the branch/screen session

    ; always separates two commands, but you were asked for one screen per line. If you wanna use one command, then don't separate them with ;. Commented Oct 24, 2017 at 13:47
