how to define variable in ssh

zwang10 — Thu, 23 Apr 2015 17:12:38 -0400

I need to use ssh to send command to different computers to run programs. Can I define a variable of Directory and program in front of this shell script? Then, I do not need to write them every time?

host_list=("c15-0330-10.ad.mtu.edu" "c15-0330-11.ad.mtu.edu" "c15-0330-12.ad.mtu.edu") # I have multiple programs # program=c("L_1","L_2","L_3") ssh -f "${host_list[0]}" 'set Directory="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"; cd $Directory && nohup Rscript L_1.R> L_1_sh.txt;echo "The job L_1 is finished" |mutt "zwang10@mtu.edu" -s "The job L_1 is finished"'; ssh -f "${host_list[1]}" 'set Directory="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"; cd $Directory && nohup Rscript L_2.R> L_2_sh.txt;echo "The job L_2 is finished" |mutt "zwang10@mtu.edu" -s "The job L_2 is finished"'; ssh -f "${host_list[2]}" 'set Directory="/home/campus27/zwang10/Desktop/AWRR/program/power/vmodel_1/nprot/K_10"; cd $Directory && nohup Rscript L_3.R> L_3_sh.txt;echo "The job L_3 is finished" |mutt "zwang10@mtu.edu" -s "The job L_3 is finished"';

How re-map the shortcut key about gnome-terminal

Marslo — Sun, 23 Dec 2012 03:09:30 -0500

According to the Gnome-Termianl Usage, I found that ctrl+shift+up/down can scroll up/down a line in the terminal.

Now, I want to re-map the shortcut key, just like: alt+j/k to scroll up/down a line, that's the old habit of vimer. :) I tried searching the settings in Edit -> Keyboard Shortcuts of Terminal, but found nothing. Can anyone help me? Thanks in advance.

The information of my computer is :

$ cat /etc/issue
Ubuntu 12.10 \n \l

How can I detach process from a terminal I don't have access to?

Joehillen — Sat, 18 Sep 2010 00:22:08 -0400

I have a server process running in a gnome-terminal at home. I am at work, and I want to detach the process from that terminal and move it to screen without restarting it. Also, I can't use VNC.

Is there a way to do this?

Jobs Control: bg keeps it going?

Klink-a-dink-dink — Tue, 27 Jul 2010 23:51:43 -0400

If I send a task to the background with ctrl+z, is it stopped?

If I type bg 1, will it keep going?

I'm just a little confused as to how background processes work. jobs and bg and fg don't have man pages.

If I have a jobs output that looks like this:

kevin@orangebox:~$ jobs
[1]-  Stopped                 htop
[2]+  Stopped                 top
