I have a file with path names to files:
/my/path1
/my/path11
/my/path12
/my/path13
The file structure is that it has individual paths in each line. All I want to do is search for the existence of a string /my/path1
or anyother in the above file many times
I could think of 2 methods.
every time get file contents line by line and then search the string. Advantage is that the file can be of anysize and I dont need to worry about buffer overflow.
Load the contents into a buffer and search it using the buffer. But as I dont have control over the file size I should be cautious here.
What is the best approach? I am working in unix. Is there any in-build library commands in C that I can make use of for this purpose? Or how can I accomplish the same task using awk
in C code.
