split function
Hi all!
I am relatively new to UNIX staff, and I have come across a problem:
I have a big directory, which contains 100 smaller ones. Each of the 100 contains a file ending in .txt , so there are 100 files ending in .txt
I want to split each of the 100 files in smaller ones, which will contain 2000 lines each.
I think that 'split' command is what I must use, but I don't know how.
I go something like:
find . -name "*.txt" | .....
Any hints on the missing part? How can I apply the split command in each file, without entering each directory?
Thanx

Hi! I'm doing bash shell scripting and would like to know if bash had something similar to perl's split function? Ultimately, I want to split two strings (delimeter = '.') and compare each of their values. Thus, I figured putting them in an array would be easiest.
So i.e.:
