Programming :: Pthread - Take String From The Command Line And Creates A Thread To Print The String
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.
Programming :: Replacing A String Of Text That Includes "/"
Sep 29, 2010Suppose I have a file named temp.txt
cat temp.txt
word/one/two/three
If I would like to replace "one" with "six" I would do this:
cat temp.txt | sed 's/one/six/'
word/six/two/three
Now I want to replace "one/two" with "six/seven" and these options don't work:
cat temp.txt | sed 's/one/two/six/seven/' (OFCOURSE)
cat temp.txt | sed 's/"one/two"/"six/seven"/'
I even want to be able to replace "one/two" with "six/seven/eight"

Mar 7, 2010i 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
[code].....
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?

View 3 Replies View RelatedGeneral :: How To Rename Everything Matching Certain String In Folder
May 19, 2010I am running Linux and I have some basic console knowledge but my current problem is quite difficult and I dont know how to achieve this. I want/need to rename everything within a folder that matches a given string.
By everything I mean:
folders/files
content within a file
content in hidden files
Basically I want to refactor a Java-project. Sure, I could use Eclipse to handle the replacing, but this leaves out the folders or resources outside of my workspace. I was thinking of a script that could do the job for me but this seems rather tricky. For instance when it comes to folder-/file-rename I want to replace only the part of the name that matches my string, the rest should remain untouched.

View 3 Replies View RelatedProgramming :: Find And Replace A String In A File Using Perl Command From Bash Script?
Feb 14, 2011I 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.
