$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?
I 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.
I'm having trouble finding information on using gstreamer to convert videos from the command line. I've seen examples to convert audio and know it's possible to convert video (Thoggen does this with gstreamer) but what would the command be to execute this? I assume it will use gst-launch but there are so many following switches that it gets confusing. I'm interested in converting a DVD to OGG (as Thoggen does). I ask this because Thoggen:
1) Doesn't remember my preferences (quality, picture size etc.) 2) Gives me a huge preview window that I do not need (while it is encoding)
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
I have a colour PDF file, and I'm going to print it out and then photocopy it in black and white. I'd like to know what it's like in B&W before photocopying it. Is it possible to 'greyscale' a PDF on the command line using free software? I'm using Ubuntu 9.10.
I've spent a lot of time googling on this one, but could not really find anything that would convert HTML to images. Does anyone know if there are some command line tools that can do this? I need to convert simple HTML documents to images to be attached to Powerpoint presentations. Could firefox gecko be tapped into to do this without a GUI?
1) capturing an RDF formatted RSS feed as a file on my computer
2) converting the result to HTML using local command line tools
I've sorted 1) with wget? I've discovered xsltproc but I'm going round in circles. The master plan is to import my pinboard bookmarks into a static web site produced on my linux box using a handful of clever bash scripts.
I am making a text search engine. I need to first convert binary documents to text. I want to go with cross-platform (we develop both on windows and linux) command line (so that I can get the output via python subprocess). What are the choices for this?
I need to be able to convert HTML email messages saved as text files (.eml or .msg) to PDF documents, one PDF per email, retaining formatting and images.
Are there any Linux tools that will allow me to do this from the command line (so it can be scripted)?
I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?
I'm building a script for my place of employment. The next step in it is checking what the user input was. Determining if they added a part in there or not. The script prompts for a hostname. Hostnames are localhost.localdomain. Now, I want the script to check to see if they put localdomain and if they did, not to add the domain to the /etc/sysconfig/network, but just what they entered. So say the user inputs:
I need to write a script that will take 1 command line argument. The argument will be a username. The script will determine if the user exists on the system and will print an error if it does not. If the user does exist it will determine if the user is currently logged in, if the user is not logged in it will determine the last time the user logged in and display the file in the users home directory that was most recently modified.

I am wanting to write a program that runs a program or command-line. Is there are way of making a program that activates a command-line (for example executing 'ps -a -f' or '/home/shared/fah').
In addition to that, I want the program to do a 'ps -a -f' and put the results in a buff, how could I do this.
I'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?
I am taking an argument from the command prompt for my shell script ie $1 and i need to use $1 in my awk part of the script.But it actually doesn't get any value when used in awk. accessing this command line argument in awk?
I've got the "OpenCryptoKi" project source from "sourceforge.net" at here:But I don't know how should I compile and build it by "GCC" or "Make"?!I have ubuntu 9.04 and I've set the linux runlevel at 3, but I'm not so familiar with compiling such project at commandline environment of linux
I just want to see how the command line such as : "cat", "split", "ls"...ect source code ? Are they written in C or other language ? I don't know where to search those?
I want to know how to get eg. the contents of a form on a webpage which has been passed to a server side PHP script, inside for example an array which I can read. I've been reading a ebook on PHP which as far as I can see doesn't cover this inside it.
