I've been debugging the following script all evening and am now stuck...this script is supposed to ssh to a router, pull interface conf, 'cut' 3 pieces of info, and then print the results of 2 as well as the 3rd (after running a ping cmd on the linux box):
SCRIPT_CODE
#! /bin/bash
lb1="0"
[code]....
i am dealing with this problemI have a function
function Une {
...
return $some_variable
[code]...
I've been trying to find a bug in this test script, but haven't been able to so far. I'm not lazy, I promise...just new to Bash so am having a hard time catching syntax errors. I call the script with the option -disableVenusBld, and it still prints "Starting build", which it shouldn't be doing right?

Solving issues with signed and unsigned numbers in BASH.For a start, Yes, BASH is type independent � I know that. My problem lays in catching executables output into a BASH variable.My executables are not quite UNIX compatible, where returned values are 0 for OK, >0 ERROR. They return 0 for OK, >0 WARNING (only, so move on) and <0 ERROR (abort) instead.
Code:
// C++ BIN A
int main(){

this might be an interesting one for the bash scripting gurus. I seem to break my teeth on it. The mission:- do a dd over ssh to trasnfer an image to another host- capture the dd PID on the other side- send a USR1 kill signal to it- capture that output on the original host It goes wrong on the last part. This is what I have before that step:dd if=image.gz | gzip -d | ssh host2 "dd of=/dev/vg1/lv1" &PID=`ssh host2 ps aux |grep dd|grep lx05|awk '{ print $2 }'`when I do "ssh host2 kill -USR1 $PIDI get nice outputs to the screen. When I replace the first line with:dd if=image.gz | gzip -d | ssh host2 "dd of=/dev/vg1/l01 2>/tmp/output.txt" &the dd command seemd to die. I suspect a problem with the pipe, since this does work when executing locally on a host without piping.

"use this linux based INE or this one or download plugins for this other one"... No, sir. I miss notepad++. I moved to linux land, (exiled from windows for having an expired VISA) and I'll do anything to get her to move here with me.
I downloaded the npp.5.8.5.Installer.exe... I have wine installed... I have no idea what directory or where in god's name this .exe exists or if i have to query wine or what.

Why isn't there a simple program like Microsoft Windows' Notepad? One which is format stupid (ASCII only), so I can over-ride hidden html character entities. The other day I found myself wasting hours trying to get the Xephyr to work by cutting and pasting the terminal instructions from the following website into a gnome-terminal session - but each time it would give me the same, small window. I tried copying the text from the browser (using copy and paste) to gedit, but gedit was not showing the hidden character entities from the html code. After all this lost time trying different resolution sizes, I became suspicious that something was interfering with my cutting and pasting between gedit and the CLI terminal. Sure enough when I compared the webpage source code it gave me the clue to the problem.
From the same page - two examples:
Hidden character (notice the '�' or × )
$ Xephyr -ac -screen 1280�786 -br -reset -terminate 2> /dev/null :2 &
NO hidden character (notice the 'x')
$ Xephyr -ac -screen 1280x1024 -br -reset -terminate 2> /dev/null :1 &
[code]....
I even tried cutting and pasting out of the terminal yet somehow it retained the hidden characters. I could not find any preference setting in any of these programs which would allow for either eliminating the hidden characters doing a cut and paste or at least revealing them. I would like to plead to programmers out there for this basic functionality...

View 1 Replies View RelatedHow do I catch the output of split and redirect it to another directory?for example,if my working directory is 'Documents' and I split a file called text.one into 4 files of 100 lines each (xaa, xab, xac, xad), how would I get those split files to be written into 'Directory/subdirectory' instead of 'Directory'?And is it possible to rename those split files so that the split name is suffixed with the original file's name e.g instead of xaa, xab... can they be written as text.one.xaa, text.one.xab..?I've thought about using '>' to send the output to a new directory but it doesn't work; and I've thought about piping the results to another command but I don't know what that other command should be.
View 2 Replies View RelatedI am trying to install vlc media player on my backtrack3 but when i am giving a command xvjf to extract bz2 file then
bash: syntax error near unexpected token `('
I've written custom prompts for several boxes but this one has an error I just can't identify and need a second set of eyes to help solve it.
I've set the following as my prompt: PS1="[e[30;42m]u@h[e[0m][e[30;47m] #][e[0m][e[32;1;40m]w>[e[0m] "
(hostname/un obscured & image enlarged slightly to make it easier to read.)
Everything looks fine initially as you can see here:url
1- It sets the username@host in back on green text.
2- It then changes to an off-white an prints the command number for the terminal.
3- Next, changes to a green on black font and prints the working directory.
4- Finally is prints a ">" character and a space.
The problem occurs when I try to "up arrow" to reuse and/or edit a prior command. It prints the prior command fine, but if I arrow over to edit the command sometimes the first character can not be deleted from displaying as you can see in the following composite screen-shot
url
Here I did a simple ps and piped it through grep. After getting the output, I up-arrow to repeat the command. As you can see by the second section the cursor only goes back to the "s" in ps. The "p" can not be deleted. Hitting enter just displays a new line, so the "p" was just a ghost being displayed and not really there.
I'm running FC10, with the sendmail that was part of it in Feb 09. Anyway, Up till now I've been using the user client to do spam filtering, But I'd like to start catching the spam at the sendmail level. What are my options today? I tried searching the forums and found a bunch of threads from 2001-2006, but I figured many of the ideas are now longer vaild.

View 2 Replies View RelatedI followed this how to document [URL] to install postfix, Amavisd, SpamAssassin and ClamAV. My postfix installation is working fine and I can send and receive emails fine. However, it looks like SpamAssassin is not catching any emails. Emails do get passed over to Amavisd as I can see in the logs but ALL Messages comes out CLEAN without being tagged as spam.
As per the document, I did test by sending a test virus email
sendmail -i your-address@example.com < sample-virus-simple.txt.
This is caught and NOT let through so ClamAV is ok but when i send
sendmail -i your-address@example.com < sample-spam-GTUBE-junk.txt
it does get delievered without being detected as SPAM or tagged as SPAM.
As I said, I have followed the documentation dot by dot and hence do not have spamassassin starting up as a service but i guess amavisd starts it within itself as a module.
Also, my postfix version is the one that supports mysql virtual tables which I got from rpmforge.
