I am trying to delete these symbols "[ ]" from a file but it says string not found. I tried: %s/[//g while editing the file not working also tried sed -e '/[/d' and sed '/]/d' still no job.

I'm running gdb across a network using gdb server. I've got it up and running. However I can't see any source or variables for my code (in ddd /gdb). At start up gdb says (no debugging symbols found). I've got a g in my make file,
CPFLAGS = -Wall -Os -g -pedantic
I've tried loading symbols in using "symbol-file testarm", this sort of works in that I can view symbols but not names, e.g. if I ask dd to show x y and z, rather than
x = 10
y = 20
x = 30
It says:
display
10/20/30
Also ddd does not show anything in the source window, is there a way I can get it to show this? I think it's because I've started ddd with ddd arm-linux-gdb, as I'm calling a crosscompiler gdb. So can I tell ddd to point to the correct folders? What commands I need to set in gdb/ddd to view variable names (it's hard to keep track when it bunches them all together) and how to view my source code.
I'm trying to get my program to go through the string typed in by the user and strip it of EVERYTHING but the numbers. I can't place my finger on what I'm missing.

I wasn't sure where to put this so if I need to move it just let me know.I have a strange problem that I cannot figure out. When I use gdb to debug our rpm-installed program, it says (no debugging symbols found) when it loads. Thing is, when I use nm on the program it can print the symbols, and even stranger is if I use gdb on the program before it is packed up by rpmbuild it loads the debug symbols just fine.Our program is built via the standard make using:GS=-g -Wall-pedantic and as I mentioned I can debug the resulting program. After the build, I package it up using:
cmd="rpmbuild -v -bb ptsnmp.spec --define "ver ${cmvc_release}" --define "rel ${cmvc_level}" --define "_topdir $rpmdir""When this package is installed via rpm, the binary on the machine shows all the debug info via nm, file shows it is not stripped:pt_snmp: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not strippedyet when I try to debug it I get the no debugging symbols found.This is really taxing my brain and I am sure I am just missing something
I'm on Ubuntu 11.04. I have read around about how to use curl to download a list of URLs from a text file, and everyone says to use Code:curl -K URLlist.txt. This is what the curl man page says as well. However, for even a simple file with one URL, this command outputs a bunch of weird symbols for me instead of downloading the file.For example, I have a text file "test.txt" with one line in the following format:
Code:
url = "http://www.example.com/image.jpg"
I use the curl command to download this file:

I have a String that I would like to sign using a given RSA Private key. I thought this would be relatively easy but I have not been able to find out how to do it, unless I'm looking to far into a simple problem. Do i have to put the string into a file, and sign the file, or can i just sign the string/message?

I have two text file named 1.txt & 2.txt.
1. txt contains 5 laks of mobile number.
2. txt has 60 laks of mob no.
Situation is that I want to find and delete numbers in 2.txt which already in 1.txt. Any perl or bash script or any other way to get the work done.
I tried the following:
#! /bin/bash
IFS=$'
' for NAME in $(cat one.txt)
do sed -ie "|^$NAME$|d" two.txt done
echo "***DONE***"
It works well with smaller file but it take very very long time even processing 10 thousand numbers.
I would like to know how I can replace a string in one file with the complete contents of another life.

I have an HP Laserjet 2200 connected via USB with 64MB of memory. When I print page 2 of this document (for example) [URL] the delta-symbol and minus-signs do not show up, although I see them in Adobe reader version 9.3.
I have tried several of the available drivers for the printer (including the "[recommended]" one) and none of them produce these symbols.
I'm guessing this is a font issue. I don't know how to show you what font stuff I have installed.

View 12 Replies View RelatedI have a quirky situation whereby I'm using SED to selectively comment out a line in a crontab job (on Solaris, I know but it's connected to the Linux function I'm working with).
What's happening is this.
Remove hash symbol
Code:
/opt/csw/bin/gsed -i '/^.*/usr/local/scripts/mirror-fix.sh.*/ s/^#//' $TEMPFILE
Restore hash symbol
Code:
/opt/csw/bin/gsed -i '/^.*/usr/local/scripts/mirror-fix.sh.*/ s/^/#/' $TEMPFILE
The problem I'm running into is that the script can sometimes prepend an extra hash # symbol if run more than once (I have a lockfile that I poll for to discourage this, but that's not perfect).
I wonder how I can modify that sed statement to remove any/all leading hash marks up to the first other character, in this case it's a 0 (zero) which is a crontab file.

I am having difficulty getting sed to replace a string of text in an XML file, despite the fact that I have no trouble using grep to find that same string. Since the new string and old string to be replaced contain a lot of special characters, I thought it best to store them in variables as opposed to using a slew of backslashes:
OLD_STRING='<property name="webServiceHost">${jboss.bind.address}</property>'
NEW_STRING='<!--<property name="webServiceHost">${jboss.bind.address}</property>-->'

InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9
What I need to do is find out what the IP address is after "ExternalHostName ="
After that I will need to compare that IP to whatismyip and if it's different then replace it but that is easy to do with sed. I just can't figure this simple hurdle out.
Is there any way i can find a file with specific word inside it.For example if i want to find a file which has some text written inside it.How would i form a command to search them?
