fix loginctl list-sessions parsing #2

Closed baodrate closed 1 year ago

baodrate commented 1 year ago

right-aligned column from list-sessions command output can break parsing with tr and cut alone. e.g.:

$ loginctl list-sessions --no-legend
  1 1000 foo seat0 tty1
464 1000 foo seat0 tty2
$ loginctl list-sessions --no-legend | tr -s " " | cut -d " " -f 1

464
$ loginctl list-sessions --no-legend | sed 's/^[[:space:]]*//; s/[[:space:]].*$//'
1
