watch command
WATCH(1) User Commands WATCH(1)
NAME
watch - execute a program periodically, showing output fullscreen- By default, the program is run every 2 seconds.
- watch -n 5 sh command.sh # executes the script command.sh each 5 seconds and show its output on the screen
screen command
Screen multiplexer. The screen command is most used for ssh session because it helps to continue your work after a disconnection without losing the current processes in progress.
# start bash in screen screen bash # detach from bash ( it will keep running) # ctrl+a d # check running processes with screen screen -ls # attach to process screen -r <id in screen -ls>
