split a file by a specific number of lines

Splits the file "my_file" every 500 lines. Will create files called xx01 xx02 and so on. You can change the prefix by using the -f option. Comes in handy for splitting logfiles for example. I am using it for feeding a logfile parser with smaller files instead of one big file (due to performance reasons)

The real strength of csplit is cutting apart files based on regular expression:

csplit splitme.txt '/xyzzy/' {*}

will split 'splitme.txt' into chunks starting with the regular expression 'xyzzy'.
