[BUG] time of last backup incorrect

[danmack]

User Story

The last backup time is still incorrect in v21.2.0

% ls -1tr lgsm/backup/*.tar.gz
vhserver-2021-03-03-133521.tar.gz
vhserver-2021-03-04-130044.tar.gz
vhserver-2021-03-05-145711.tar.gz
vhserver-2021-03-06-111752.tar.gz
vhserver-2021-03-06-115542.tar.gz
% ./vhserver backup
[ OK ] Backing up vhserver: Backup starting

• Previous backup was created 2 days ago, total size 772M
  [ OK ] Backing up vhserver: Completed: vhserver-2021-03-06-115742.tar.gz, total size 773M

The command on line 215 does ls -1tr | head -1, it should probably be ls -1tr | tail -1

ls -1tr lgsm/backup/*.tar.gz
vhserver-2021-03-03-133521.tar.gz
vhserver-2021-03-04-130044.tar.gz
vhserver-2021-03-05-145711.tar.gz
vhserver-2021-03-06-111752.tar.gz
vhserver-2021-03-06-115542.tar.gz
% ./vhserver backup
[ OK ] Backing up vhserver: Backup starting

• Previous backup was created 2 days ago, total size 772M
  [ OK ] Backing up vhserver: Completed: vhserver-2021-03-06-115742.tar.gz, total size 773M

Basic info

• Distro: CentOS 8 stream
• Game: vhserver
• Command: backup
• LinuxGSM version: v21.2.0

Further Information

A clear description of what the bug is and any ideas on how to resolve it. Plus any further context that might be relevant to the issue.

The last backup message is incorrect because lgsm/functions/info_distro.sh:215 is using head instead of tail.

To Reproduce

./vhserver backup

View output and manually compare with list of your backups

Expected behaviour

[h3o66]

That seems to be regressed by #3328
Added a new PR that should add this with a differnt approach (disablle reverse sorting by ls instead)
