Code: 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?
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.

with that said i burned fedora 8, 10, and 11 checked the sha1 verified everything was fine i had originally installed fedora 8 on an old pc i had from windows XP without any problems messed with it some, upgraded to 10 again no problems. tired to update 11 got a message about ext3 not found ext4 not found, re installed 10 the loader loads up now i have a blank screen with a cursor it the left hand corner
again i had 10 installed fine prior to all this can any one point me in the right direction to solve this issue or am i way over my head trying to figure this stuff out. i have spent 3 days searching these forums.
i'm just not quite sure what i need to do. oh, i tried to install 8 again and it wouldn't take either. i think the 10 problem has something to do with the graphic driver it's a geforce 7400 nvidia and something to do with the grub, but like i said i get a blinking cursor and not quite sure how to access the grub or command line.
I cannot connect to the internet on the command line. Things like firefox or chrome browser work fine. But on the command line programs like 'links' fail to work. This is on a machine behind a proxy, I have the http_proxy and https_proxy environment variables set properly.
View 5 Replies View Relatedmy fedora 14 did an automatic update tonight and on reboot it hangs displaying the "f" before the login in menu. The "f" is how I now feel.I do "fn+f2" as it is booting and it displays the sequence of loading items which report all is "ok" until it gets to "jexec services" and then it hangs.I do not know how to access the machine in command line mode and I am not sure what to do from here. I beleive the "jexec service" is a Sun Java item but I am not sure.

I have Red Hat 5.4, and I'm trying to log in using tty1 by pressing Ctrl-Shift-F1. I get to the text login screen, my banner displays, but when I try to log in as root, the banner just displays again and it asks me to log in.
It does not say that my password is incorrect, just asks me log in as if the previous exchange never happened. I have added tty1 to /etc/securetty, and all the other tty's and vc/1, vc/2, etc...in an attempt to get something to work. I recently started using PAM for password authentication, and the pam_securetty.so line is set correctly in /etc/pam.d/login. Any idea why I can't log in? Did I miss something I have to add?

Is there any way to install a Ubuntu server and access the server remotely via a Ubuntu desktop environment instead of a SSH command line?
I will be installing a Ubuntu server in an office where the office manager will need to be able to do simple things like add/remove users, access filesystems, etc. She can handle these tasks in Ubuntu desktop/GUI, but it is impractical for her to have to learn how to use the CLI terminal to do this stuff.
Will I have to install desktop Ubuntu on the server to do this, or can I install Ubuntu server version and setup another computer Ubuntu desktop to remotely login graphically?
Does anyone know from experience a good gdb tutorial, so I can learn to use it from the command line.
View 2 Replies View RelatedI'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 using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
cat file.csv | awk -v sign=">" -v field="2000" '{if($3 sign field) printf "%-12s%-12s%-12s%-12s

the bold part is the problem , because when i put the sign parameter myself t works great.. i guess its a chars issue but i cant spot it

This is the script I wrote:

synclient VertEdgeScroll=1
syndaemon -d -t -K
exit 0
So I made a chmod +x on the file, placed it in ~/bin then change PATH to include the directory. Then I added this file in "Startup applications".
The scripts run ok, mais it has a different effect than if I run the commands manually.
