Description: Add lookup code for the creation time of each session.
|
|
Requires digging in /proc/$pid and /proc/uptime, though, so it's
|
|
definitely no candidate for the Beautiful C contest.
|
|
.
|
|
Affects screen's behaviour in the following situations:
|
|
.
|
|
* 'screen -ls' lists available sessions sorted chronologically
|
|
* 'screen -RR' now picks the youngest session instead of an
|
|
arbitrary one
|
|
.
