I'm currently on a Linux machine and the shell prompt is showing me the last return value and number of executed commands (picture included, with these numbers shown in purple).
My own computer doesn't have this, how can I configure it? I'm using Xubunto, if more details are needed let me know -- I'm not much of a Linux user (I don't know what's relevant here).
Whenever I go inside a directory in Linux, it shows the file path at prompt like:
root@vivek-HP-Pavilion-dv6-Notebook-PC:/var/www/abc/def/
How can I change it to show short names instead?

View 1 Replies View RelatedI have a script in /etc/rc.d/init.d named foo. I want to start/stop/restart my process as follows:$ foo start But I do not see the [OK] message once it starts. There is no shell prompt returned either. It seems that my own process is the problem. The executable that foo calls is built from this sample code:
int main()
{
do {
printf("Hello world
");
sleep(1);
} while (1);
}
Do I have to return some kind of signal handle for this to work?

View 5 Replies View RelatedI have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).
Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands
The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?
When I run startx from a console in Slackware 13.0 the prompt does not return and the console becomes useless. The console does not respond to any keys except to print control characters on the screen. Shouldn't the prompt return in the console after x is running? I have to login on a different console if I want to use a console.

I have named my script "foo", then I can start running my application my typing $ foo start but this does not return [OK] like other scripts do and does not return to shell prompt. My application is basically like this

What is missing from my application that prevents from returning the shell prompt?
Because I have to stare at my command prompt all the time on my computer, it should look at least half-decent, so I am trying to get it colored. The expected outcome is as seen on this site. I have the colors I want set in my .Xdefaults file, but they of course do not color my prompt.

Currently the terminal prompt looks like this:[karlis@karlis-desktop current_folder]$How can I minimize the prompt, so that it only shows $ or # without extra info in square brackets?I checked the preferences for the default Gnome-Terminal and Terminator - there are no settings for this. It is pretty hard to use terminal when working in directories with long names.

I need to create a shell script called 'custinfo' to prompt a customer to enter and display back the following: name, age, address, phone number, and product.
Below is what i have so far.
I would like to run some existing scripts and send it to a text file:
Note: 'script' is an exist shell script
Note: '/opt/2011jun15/my.db' auto generates everyday with only changes to the directory 2011jun15 base on the current date
currently i will need to run the script manually and make changes to the path below, change directory name 2011jun15 daily and text file new2011jun15.txt ./script -f /opt/2011jun15/my.db > new2011jun15.txt
Am i able to write a shell script to prompt me for a change of path for only '2011jun15' and 'new2011jun15.txt'?
It will be great if i can automate the whole process?
This issue is similar to thread [URL] .... and it goes like this:
Eterm can be started either from the menu or from the command line, but it returns no prompt. It just hangs there, displaying a backdrop within the terminal, pressing <Enter> just moves the block cursor down and other input keys appear normally in the terminal, there is just no response or interpretation from the shell.
It seems that for some reason the shell (bash in my case) just does not interact with Eterm application.
One more point is that if the Eterm is terminated by the Close (X) Button, it seems to go in some kind of loop and needs to be killed from the command line (killall Eterm), whereas SIGINT (<Ctrl>+<C> inside the Eterm window) exits properly with no leftover zombies.
I would like to modify Bash Prompt so it does not show the whole $PATH but just the current and parent directory. I am using Ubuntu.

from paul's reply in the link (http://www.linuxquestions.org/questi...c-code-181152/) , I am trying to retrieve the count from a shell script using option 1: below is the system call that I have used to call my shell script named "test"
Code:
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i;
i=system("./test 1234");
[Code]...
Here "test" is the shell script that is fetching the count from a table for a particular column("1234") that I am passing as the parameter. When the "test" script alone is run, it is returning the correct count but when trying to check through the C program it's returning some different value. How can I get the exact value from the script in my program above?
I'm trying to create a super simple shell script, but I cant get a return line. The shell script looks like this (only the part that matters)
Code:
yes '' | ssh-keygen
The idea being it will put in a blank char. Then enter until the program finishes. The problem is, it only does the first time, the next 2 times I have to hit enter, it requires me to input it manually (which is exactly what I'm trying to avoid).
The full script (if you care):
Code:
#!/bin/sh
# Created by Omega
# First, program creates RSA key, named id_rsa and id_rsa.pub
# Second, program send the public code to requsted server.
echo 'Removing old id_rsa key (if applicable)'
rm -rf ~/.ssh/id_rsa.pub
rm -rf ~/.ssh/id_rsa
echo "Creating RSA key"
yes '' | ssh-keygen
# Checking if ssh-kkeygen created requested file
if [ -e ~/.ssh/id_rsa.pub ]
then
echo 'Done'
echo 'Username and Server in: me@server format'
read var1
echo 'Port Number? If standard put 22'
read var2
ssh-copy-id -i ~/.ssh/id_rsa.pub "-p $var2 $var"
else
echo ''
echo 'ERROR, ssh-keygen did not execute correctly'
echo 'Retrying...'
echo ''
echo 'Please leave all options default (just press enter)'
ssh-keygen
if [ -e ~/.ssh/id_rsa.pub ]
then
echo 'Done'
echo 'Username and Server in: me@server format'
read var1
echo 'Port Number? If standard put 22'
read var2
ssh-copy-id -i ~/.ssh/id_rsa.pub "-p $var2 $var1"
else
echo 'ERROR, ssh-keygen did not execute correctly'
echo 'Quitting'
exit

I have a few questions regarding HTML, UNIX and Javascript. I've been tasked with creating a fairly simple webpage that takes a few inputs. Each input must correspond to an argument in a UNIX command running on a server.On a UNIX server we have a script (.ksh) that takes 3 arguments. The result of the script is a data file which is FTP'ed to an external server. Let's forget about the FTP portion for now. I would like to know where I should begin.What I know so far:
1) I will need HTML to create the webpage. Skill level is high
2) I will need Javascript to make my webpage more interactive. Skill level is high.
3) I will need to understand the UNIX environment. Skill level is high.

I just added a new user to my ubuntu by:
useradd -gdevelopers -d/home/peter -m peter
when peter logs in (after I created a passwd for him) he doesn't see the shell as I do:
me:
adhg@server:~$
peter
$
ALSO, he can't user the TAB to move inside a folder (when you type cs /home/p and use tab to get /home/peter)
After I succesfully instaled ubuntu 10.04 server, I applied
export PC1="[e[36;1m]u@[e[31;1m]h:w$ [e[32m"
and my prompt was nice and colorfull. But, when I make logout and login, my prompt appears all green ([e[32m.) After restart, nevertheless, it looses color settings (of course) and appears plain white.
What should I do in order to keep my prompt color settings permanently?
I have no user name or password and cannot log in. In recovery mode, I after I enter "drop to root shell prompt" my keyboard does not respond when I try to "give root password for maintenance" or try to enter "Control-D" at the blinking cursor.
