End Task and New Task in linux.

[hack3rcon]

Hello,
In the Windows OS, you can end a program and with the New Task button start it again. How about Linux?
With "kill -9 " Process ID" " we can stop a program but how about start it again? Any command?

Thank you.

Your welcome.

Key words =

Code: Select all

With "kill -9 " Process ID" " we can stop a program but how about start it again? 

Hint:

In this tutorial we see how to manage processes with the Linux command line. ... If you close the xload window, the xload program terminates and the prompt returns. ... we are going to launch the xload program again, but this time we will put it in ... With ps, you are given a process id (PID). ... [me@linuxbox me]$ kill -9 2931 ...

SIGHUP might work and some programs employ SIGUSR1 or SIGUSR2 for restarts:

Code: Select all

pkill -hup -x $process
pkill -usr1 -x $process
pkill -usr2 -x $process

^ Replace $process with the actual name of the process.

EDIT: see signal(7) for a full list of signals.

How about start it again? Just write the program name?

You could do it that way as well, type in the program name, and hit enter.
