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"

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.

View 6 Replies View RelatedProgramming :: Prevent Sed From Replacing With Newline
Nov 28, 2009I'm writing a script to replace some text that exists in about 50 .lex, .y, and .cc source code files, sometimes more than once in a file. Sometimes the text is in a multiline C comment, and other times it's within a multiline C string.
I use sed to grab the start and end of each line and wrap the new text in the old whitespace and/or quotes and Problem is, sed is changing the characters into a newline.
Is there a way to tell sed to not process escape sequences? I tried using several variations of
Code:
To no avail. Or could it be bash?
I would give up on the script and do it by hand, but this is something that I must do from time to time.
Here's the function which replaces the first occurrence found:
Code:
When $post is printed by echo, it shows the - but by the time the file is on disk, it becomes a newline. What should I do to ensure that it stays as the characters ?
