Keep Command running on power off ??
| Posted by VpsHosting, 02-22-2008, 10:03 AM |
| Hello
is there any way by which we can keep the command running on PUTTY even when there is Power Failure on our local computer.
What i mean is -
Suppose i am running a TAR command on my BOX and suddenly Power goes off my local PC, so when i relogin i have to start from starch,
is there any way to avoid it, and login back to putty and resume the session ?

| append & at the end of command to make it work in background
for example
for some reason if you want to bring it back foreground use fg command

| You can run the command in screen. Use the command screen -S screenname to start a screen and run the command to untar the file in that. The command
screen -ls will list the screen. To quit the screen without interrupting the process running in the screen Ctrl + A + D. To enter the screen again screen -x screenname.
Hope that helps.

| It's identified by 18017, not 123, I believe.

| It's likely trying to look for the PID instead of the name since you used a numerical name. Just do "screen -x 18017" instead (or screen -x if it's the only screen you have created).

| I usually run "screen -r" to resume the screen session that I had going. Of course, that really only works correctly if you only have one screen session at a time. But since I only use 1 screen session and launch multiple shells from inside it (Ctrl + a, c), I almost never have a problem.

| You can also use "nohup", man nohup for more information.
e.g. if your original command is "tar xzf data.tgz"
You can use "nohup tar xzf data.tgz > tar.log 2>&1 &".
Even if your network connection is lost, the command will finish successfully.
