Programming :: Why String In The Middle Surrounded By Parentheses And Preceded By An Underscore
Mar 23, 2011I have been reading through C source code to try to improve myself. In the coreutils source code, there are often function calls like so:
Code:
fprintf (stderr, _("Try `%s --help' for more information.
"), program_name);
Why is that string in the middle surrounded by parentheses and preceded by an underscore?
Programming :: Need To Delete A Specific String
Aug 27, 2010These must a be a question you received a lot, but I couldn't find a similar thread! It's a simple question.
I need to delete a specific string from a file. For example the specific numbers "3456" from a file. I've tried with the tr comand, using
Code:
tr -d '3456' file,
but it also deleted whichever ocurrence of 3,4,5,6 from my file. Should I use a regular expression?
Programming :: Delete Line In File Matching String?
Jan 26, 2010Quote:Originally Posted by topcatI would like to know how i can write a shell script to delete a line if a particular pattern exists?E.g. I have a text file with multiple lines. Say 1000s. in the following pattern.
username@email.com:149.0.3.4:1
username1@email.com:149.0.3.4:1
username1@email.net:149.0.3.4:1
username1@email.edu:149.0.3.4:1
If the patternusername@email.com exists then the line "username@email.com:149.0.3.4:1 should be deleted from the file.I have a very similar question but I need to delete one line in a file which matches one very precise instance of a string only. Let's assume I have a file composed of thousands of lines and let's call the file chap-secrets. Let's take the following sample entries:
Code:
#USERNAME SERVER PASSWORD IP

Programming :: Use Sed To Find String Pattern And Delete Subsequent Characters?
May 3, 2010I have a file with a number of strings like the ones below
string1#m1asdfe23easdf23wefas
string2#mfaaeb2vr1rhserh
anotherstring#ji89ensrsegr
anotherone#m1ynmdt324nsdt
I'm trying to delete everything after #** so that
string1#maasdfeaveasdfawefas
string2#mfaaebvrserhserh
becomes
string1#ma
string2#mf
tried sed 's/#..*//g' but as you all will know it returns string1, string2 etc.

May 3, 2011I'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 know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

Software :: Find And Delete String In Text Files?
Mar 6, 2010I have a series of file names in a text file that I generated by running

General :: Delete All Lines Containing A String, Plus 4 Lines Below It?
Jan 26, 2010I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)
