Programming :: Diverting IDL Output To The Command Line?
Jul 14, 2010I'm troubleshooting a batch of scripts I'm modifying, including an IDL script called by a .csh script. the IDL scripts were provided to me by a coworker and my .csh script is intended to automate a lengthy set of extremely tedious and time consuming processing tasks.
I am currently in the process of debugging, and can't get the IDL to print any messages other than critical failures to the screen. Is there any easy way to redirect the stdout to either a logfile or the screen?

General :: How To Truncate Command-Line Output
Sep 6, 2011If I grep -nr sumthin * in my source code directory, it also spews out very long lines from minified JavaScript or CSS files. I want to get just the first 80 characters per line. For example, a regular grep gives me this:

css/style-min.css:4:.arrow1{cursor:pointer;position:absolute;left:5px;bottom:10px;z-index:13;}.arrow2{cursor:pointer;position:absolute;right:5px;bottom:10px;z-index:13;}.calendarModule{z-index:100;}.calendarFooterContainer{height:25px;text-align:center;width:100%!important;z-index:15;position:relative;font-size:15px!important;padding:-2px 0 3px 0;clear:both!important;border-left:1px solid #CCC;border-right:1px ... etc.

General :: 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.

Programming :: Effect Of Using Eval To Execute A Command As Opposed To Writing It On The Command-line?
Jun 18, 2010Code: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
Programming :: Command Line Invocation Of Gnome-terminal To Run More Than One Command?
Feb 16, 2010I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.

Let say I want to create new file with the output of first column and do something else with the output of 3rd column. Of course there are many ways to process this data file, but I wish to know by using awk, how could I do it. I'm trying:
Code:
awk '{system("touch $1")}' datafile
but the shell command will not able to get the awk '$1' output. How do I get this done ? And for another question, if the data file contains the variable name of a shell variable, how could I make use of it during a awk output ? For example I have a datafile1:
Code:
server1 yes
server2 no
And in another server declaration data file, I got this datafile2:

server1=xxx1
server2=yyy1
