I need a hand with a line of terminal commands. I need to be able to search a given .sh file in a given location for a string, and when found, add a "#" to the start of that string and save the file back to it's original location.
View 1 RepliesI am using grep command to search in a particular file whose size is 11 GB and i am getting Segmentation fault error as an output. My command and output is as follows:
Code:
[sdpuser@gnnsdp40 test]$ cat new* | grep 8858406465
Segmentation fault
My linux version is as follows:
Code:
[sdpuser@gnnsdp40 test]$ uname -a Linux gnnsdp40 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
how i can parse the complete file for searching string. I have also used split command of linux which splits the file of 11 GB to 11 files of 1 GB each respectively. But still getting the same "Segmentation fault" error while using grep.
I have a file which provide the output of all the applications which started and running successfully. But it doesn't give the Error message of the applications which are failed. For example there are 5 applications (ABC,DEF,NMO,STO,XYZ) and application STO failed so I will get the following output (out.txt). content of out.txt file
Application ABC is Running
Application DEF is Running
Application NMO is Running
Application XYZ is Running
I want to generate the text message based on the information on out.txt that STO application is Failed.
I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.

I am a member of a group which has written a program whose source code is being held in a specific directory (~cs252/Assignments/basicAsst/project) and we want to go through and change the parameters for the function "sequentialInsert." My job is to find all occurances of the function call to "sequentialInsert" and to also list the files from where the code came from. Also, I have to be in the commandsAsst directory when I do this. I have tried grep and find combined together, and I am at a lost.

View 3 Replies View RelatedI've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
View 4 Replies View RelatedI wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.
I need to run a script that I build to build a word list. Essentially what it does is run through a base list and expands that into billions of words. This way I can keep a small dictionary file and a script to expand it into a larger file (about 500 gigs). This script should take anywhere from 12-14 days to run and on my last day the power went out at my house. Is there anyway I can run this again with a fail over system? I know a battery back up is an ideal addition to my home server but if the power is out for an hour it wouldn't have made a difference. Also if I had the ability to pause the script do a reboot and resume it again that would be amazing.

Well i downloaded a program with many .deb files ( At least 15 ) so i wanna execute them all trough the terminal so i typed
Code:
patowlmc@patowlmc-desktop:~$ cd /home/patowlmc/Downloads/i386
patowlmc@patowlmc-desktop:~/Downloads/i386$ sudo dpkg -i *.deb
Readme.deb: command not found
As you can see all files in the folder are .deb packages, but one: The Readme file, wich is a text file.
I know I just have to move the file to somewhere else, and everything should work, but i wanna know if there's a command for excluding a file or something.
P.D. I totally trust the program, so don't worry about so many .deb files.
i use this script to get the time and date of back and fourth transactions for a particular execution id. I use a substr command on the 5th column to to cut the milli seconds off the time value. - otherwise the times would look like 08:30:04.235
grep <executionID> <auditfile> | awk '{ print $1, $2, $3, $4, substr($5,1,8}
FIX -> Mon 3/1/2010 08:30:04
FIX <- Mon 3/1/2010 08:32:36
FIX <- Mon 3/1/2010 08:35:08

anyhow - i append two sed commands to further clarify the direction of the message.
awk '{ print $1, $2, $3, $4, substr($5,1,8} | sed -e 's/->/ ->IN/g' | sed -e 's/<-/<-OUT/g'
FIX -> IN Mon 3/1/2010 08:30:04
FIX <- OUT Mon 3/1/2010 08:32:36
[code]....
I tried using an awk gsub () command within the string instead of the two seds, but it did not work:
awk '{ print gsub(/<regex>/, <replace with>,$1), $2, $3, $4, substr($5,1,8}
the sed works ok, but it would be cooler to make the replacement within the awk command:
gsub(/->/,-> IN, $1)
Is there a way where i could replace the value of the $1 column in the awk print string?

I use webcam with the streamer application. So, to record a video I have to put in terminal something like this:
Code:
streamer -q -c /dev/video0 -f rgb24 -r 24 -t 00:30:00 -o /home/shark/untitled.avi
I know I can use other applications but I have got problems with all except with this. This is really annoying because it is a delay job. So, I am wondering how can I make a script that the terminal will ask me to name the file or even better to ask where to put my file.
I've got some photos with two or more tags on and I was wondering if there was a way of only showing photos that had one tag and not another.

View 2 Replies View RelatedI've recently installed matlab and after some poking around found that you must start it using a script like:
#>> cd ~root/../matlab2009/bin/
#>>./matlab
the manual tells me that the installation should have made it so that all you have to do is type matlab at the terminal but for some reason this hasn't happened. If you did not set up symbolic links in the installation procedure, you must enter the full path name to start MATLAB, matlabroot/bin/matlab, where matlabroot is the name of the folder in which you installed MATLAB. I've also looked at documentation on ln but most refers to making links between files. Is there a way to link the command "matlab" to the file shown above so all I have to do is type the command and it runs the script?
p.s: Here's what I've tried:
#>> ln -s ~root/../matlab2009/bin/matlab matlab
linux-2fs6:/home/alex # matlab
If 'matlab' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf matlab

View 5 Replies View Relatedmy laptop seems to have a bad HDD, and I was thinking of trying to make it a "thin client." However since it is a laptop obviously I want to take it places. Is it possible to make a terminal server and "thin client" connect through the internet and not just LAN?The reason I quote thin client is because in my mind I am still going to need to use some HDD so I can connect to the internet and find my server.
To make things easier to read refer to the above as "question 1" and the velow as "question2" Thank you. And sorry for the inconvience. These topics I felt were to similar to make separate topics.I also have another question, the files I have on my server can be accessed by anyone on the network(added a second HDD and network shared it) how can I make it so that the LAN clients have to "login" (or it uses their computers login info to send them to only their files? And if that is possible can we expand it to allow me to use those logins through the internet?
