If you don’t have it installed.
yum install screen apt install screen |
yum install screen apt install screen
Before you run a process, run screen, and detach.
screen # run the command ping yahoo.com # ctrl-a and ctrl-d to detach |
screen # run the command ping yahoo.com # ctrl-a and ctrl-d to detach
To reattach, get a list of screen sessions, and attach to it.
screen -ls # result is somewhat similar to below 4452.hostname # attach to it screen -dr 4452.hostname |
screen -ls # result is somewhat similar to below 4452.hostname # attach to it screen -dr 4452.hostname
To stop, just type exit from the screen terminal.
Here’s a quick way to chroot another boot disk. Attach the rescued boot disk first. Run lsblk and mount.
lsblk mount -t xfs -o nouuid /dev/xvdf2 /mnt mount --bind /proc /mnt/proc mount --bind /sys /mnt/sys mount --bind /dev /mnt/dev chroot /mnt cd /mnt exit |
lsblk mount -t xfs -o nouuid /dev/xvdf2 /mnt mount --bind /proc /mnt/proc mount --bind /sys /mnt/sys mount --bind /dev /mnt/dev chroot /mnt cd /mnt exit
Unmount when done.
umount /mnt/proc umount /mnt/dev umount /mnt/sys umount /mnt |
umount /mnt/proc umount /mnt/dev umount /mnt/sys umount /mnt
