Does anyone know a way to change the default 80 columns width when starting screen in 'detached' mode (screen -dm) ?

Smart curses apps like htop handle resizing when attaching from a wide terminal later on, but for dumb scripts like this it's too late :

#!/bin/bash    
echo "Scanning packages:"    
COLUMNS=132 dpkg -l | tr '\n' '\r'    
echo ""
echo "Done"

Direct screen session (from a wide term) works fine :

$ screen bash -c './myscript ; exec bash'
Scanning packages:

Done

But in 'detached' mode 80 columns width messes up everything :

$ screen -dm  bash -c './myscript ; exec bash'
$ screen -r

   ...

Looks like neither stty, width command or COLUMNS env variable is going to do it here, really need a way to start with a wider term ...

  • Does setting focusminsize in your screenrc help? – jofel Jan 8 '16 at 11:41
  • hmm, no luck with focusminsize so far ... – lemonsqueeze Jan 9 '16 at 0:15
