It's sort of a database table (or a CVS file if you like). Every line contains a unique element that determines what should be done. Of course, I could go a grep on the file to find out the elements, but this would give a complexity of O(n^2).
I know that every line is processed only once, and the pointer to the current line will never go back. So I figure out that I could read every line in an array element and I could process line by line. This would give a O(n) which is much faster. -- View this message in context: http://www.nabble.com/Problem-with-reading-file-and-executing-other-stuffs--tf4733602.html#a13651074 Sent from the Gnu - Bash mailing list archive at Nabble.com.
