I am trying to write a script that connects to a server and executes some commands on there. Something like this:
#!/bin/sh
telnet remote_machine
cd /home/some_directory
cat a_file_in_current_directory
Unfortunately after login/password I guess the script doesn't jump past the telnet command, until I exit. What do I need to do to make the script start executing commands in the remote shell?
I would like to make a script, where I specify my Cisco devices IP addresses as arguments to the script and then this script automatically logs into every one of them and does "show version" and "exit" in every Cisco device. I have public/private key authentication system with my Cisco devices- thats why I'm using ssh-agent and ssh-add. I did something like this:
Code:
#!/bin/bash
if [ -z $1 ]; then
echo USAGE:
echo "$0 IP1 IP2 IP3 IPn"
[code].......
However, it logs nicely into the first device(I'm able to execute IOS commands in this first Cisco device etc) and then does nothing further.
I want to use a desktop icon shortcut that essentially does this...
Is there a way I can do this? I don't really want to create an alias because I just want it to be an icon I double click to do all of this. But if I have to create an alias in which it does these ocmmands then I use the shortcut to terminal... then it types the alias that is fine also.
I have a computer with a trackpad and a touchscreen. I want to run unclutter if I use the touchscreen, and kill it when I use the trackpad or a USB mouse.
The I'm pretty sure the touchscreen is /dev/input/mouse0, and the trackpad is /dev/input/mouse1
I have a general idea of how this should work, but no idea what tools and commands to use to implement it.
I am trying to create a RS232 C program that executes a series of commands down the line to a robot. Everything seems to work fine, except any sequential write to the serial port. At first I thought it was the UART's buffer being filled too fast, but even with a 50 uS delay it still throws the error.
Here is my code:
Code:
#include <termios.h>
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>
#include <sys/signal.h>
#include <sys/types.h>

I centos version 5 installed on server 2, and I want to make a scheduled task that executes a shell script.This script should copy some files and directories from one server to another. I do not use DRBD and Heartbeat.
View 1 Replies View RelatedI would like to a build a CD image (of CentOS 5, x86_64 that loads into memory and boots to the OS without installing anything to hard drives. Then I would like the system to execute a shell script automatically. The shell script will have commands that will control execution.
The goal of this exercise is basically to pre-configure a system (RAID config, BIOS update, etc) automatically using the shell script before installing the OS. I would like the ability to change the shell script as needed and probably repackage the ISO image. I would prefer not to deal with building a source tree to accomplish this. this is something one could do using mkisofs.
Is there tool or a regexp that can convert shell escape characters to HTML code?
As an example, here is a logfile from GNU screen:
Which I would like to convert to something like this:
And send as HTML e-mail to an e-mail address, to archive my work.
Here is a related question, which shows how to convert it to regular text, but it would be nice to convert to HTML and not just throw the escape characters away.
I need to remove a large binary file(PDF file) from a large log file which is generated daily.This is seriously hogging space on our servers.I need to remove the large PDF from the logs to make the logs smaller and manageable
I need to take out the texts (or binary file) between the strings
<my:PDF> and </my:PDF>
<applicationForm> and </applicationForm>
<image> and </image>
<extractedSignature> and </extractedSignature>
I am not sure whether sed utility can do this, these are large files and need to be pruned .I am not seeking logrotation advice just a script or command that can strip these large logs of texts between the characters above . I am not sure how to do this.These files are rather large.I am not sure how to achieve this with sed , tail, head , tr or any other facility .
Programs like matlab/octave and I'm sure many other ones allow you to start typing a command, and then hit Up to recall the last command that starts with the typed characters. Common linux shell bash doesnot do this. Is there a different shell that does? I'm not asking how to find out the last command, I'm asking if there's a shell that's a little friendlier.

How can I do this with shell commands in Linux?
My current thoughts:
ssh <user>@<computer1address> -p <port> - gives me a shell on the remote computer
(I think I should use scp, but I dont how exactly how in my case)
What are the exact commands I should use?

I am new to Minix. I'm so impressed by the speed of the system. It looks elegant, I like it. However, I have a question about the shell. In Linux, while using a shell, up and down arrow keys can be used to navigate through previously executed commands. On Minix with the sh shell, I can only get numbers printed out on the screen. I remember I chose a US-std keyboard when installing. Is there any way to use the arrow keys to navigate through previous commands on Minix?

View 1 Replies View RelatedThe panel plugin from xfce4-mixer has a bug:s icon doesn't update as the volume is changed. This bug has already been reported.One curious thing about it is that, if you right click on the volume icon on the panel, go to 'Settings' (or 'Properties', I don't know, mine is in Portuguese) and then close the window that pops on the screen, the icon is updated.Is it possible to open and close the settings window automatically with a bash script? Like this, I could associate this script with the volume keys of my keyboard, so that the icon is updated as the the volume is changed.
View 2 Replies View RelatedI have a hard to reproduce (seen a couple times in a month) issue where my program seems like it is hung (not increasing in cputime), however, it is in the runnable state and never gets to run. The cpus are 99% idle according to vmstat and the load is 5 (which is equal to the number of threads in my program that are in the R state) according to ps, and there are no processes on the system in the 'D' state. The other major oddity is that one of the migration threads has a cputime usage almost equal to the uptime of the system. Typically migration threads have a cputime on the order of seconds across hundreds of days of uptime, but in this case the migration thread has DAYS of cputime according to ps.
The last time this happened, I went around saving as much /proc/X information that I could into logs for referring to later, before I had to reboot the box to get it running back to normal. (because in this state, a kill -9 is not heeded by my program)Does anyone have any idea what could cause this? I am not sure if this is a scheduling bug or a bug in my program (the likelier case).I have a wealth of logs to look through if anyone can suggest something specific to look for.

Iv got an assignment to complete and I'm stuck at the basic level.
A part of the assigned problem is :
The main process will read the file, and will create N number of child processes (Where N is taken as input) as early as possible before all the children starts its execution. Before creation of each child, the main process should read the file to store all the required data in then corresponding data structure. Child processes should not read the file for getting their information.
As far as my knowledge about this , the child executes before the parent. How do I make the parent not pass the control to it's children before it finishes creating all the children?
I have a logfile which looks like:

Now i have to writ a script which takes this log as input and quesries the DB for each table. So,I want to: input the logfile
start a while loop.So,while read LINE This variable LINE would store the table name by CUT using a delimiter once the table name is ready it makes a connection to DB and queries the table for its rowcount writes the rowcount to an O/P file.
