View 1 Replies View RelatedGeneral :: Running Script On Ssh Command Line Want To See Output?
Jun 2, 2011I'm trying to remotely run a script on a target machine though the ssh command-line using passwordless login. I know the keys are set up correctly because if I remove the call to the script, the ssh session succeeds and I can log into the remote machine, but when I call the csh script, I don't get any output on the command line. If I call an identical bash script, I do get the output. Specifically, calling line 1 below just returns me to the command line, but running line 2 echo's hello then returns to the command line (both scripts simply contain a single line to echo hello, and both work when run locally on the remote machine). Why do my csh scripts send any output through the ssh link whereas the bash does?
Code:
1) ssh -i /root/.ssh/id_rsa user@remotemachine /tmp/test.csh
2) ssh -i /root/.ssh/id_rsa user@remotemachine /tmp/test.bash Update: I have further determined that nothing I add to the csh gets run either. I've tried touching files and making directories in the scripts, and all gets run using the bash script, but calling the csh script like line 1 above does nothing, nothing is touched or created.
Software :: Error - Bad Passphrase Gpg Command Line And Output
Jul 22, 2011I have copied over my .gnupg files from a computer to a new workstation that is running Mandriva 2010.2. I am running Thunderbird as a mail client just as before and got Enigmail installed and running fine. The problem I get is when I send a message off with a digital sig it returns this error:
Send operation aborted
Error - bad passphrase
gpg command line and output:
/usr/bin/gpg
gpg: cancelled by user
It does not give me a chance to enter in the passphrase. I copied over the .gnupg files to my Ubuntu laptop running Thunderbird with Enigmail and I have no problems. Could there be an issue going from 32 bit to 64 bit? I checked out the forums and found no answers.
Fedora :: Route Line-in Audio For Output To External Speakers
Jan 29, 2010i'm running fedora 12 on a dell dimension 4600. audio seems to work reasonably well for things like flash animation but i cannot for the life of me figure out how to route line-in audio through the system for output to my external speakers. on the sound preferences application on the gnome desktop: if i select the hardware tab and analog stereo input is selected, then i go to the input tab and have analog line-in selected, i see the v-u meter above moving around as though there is actually an input. [list]
but, i hear no sound. the output tab shows "dummy output" with no other choices. to get audio working for videos and other flash sites, i have to change to hardware->analog surround 5.0 output. such documentation as i have been able to find doesn't seem to describe my setup well, and in any case, i find all this fidgeting with hardware configurations an immense step back from the old alsa software. if this is going to be the future of linux audio, can i say, please, no?

Programming :: Copy And Replacing Specific Line From File1 To File2 Line By Line
Mar 22, 2011I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.
