Reading a list of data into a function using a script.

contributed by Jimmy Selix on July 24, 2005 under Korn shell

Well, i’ve been a ksh geek for only prob 2 years now, but my job requires the managing of HUGE amounts of files and data (usually about 6500 files/items per query,set). Managing and querying such large amounts of data by hand is impossible and just a waste of time when you can have a ksh script do this for you! This recipe is just an example of what you can do with some variables, menus, and functions!

This recipe explains how to use the xargs command in ksh to work with multiple files. This recipe will show how to combine 10 files together into one file without manually doing a: cat file1 > bigfile, cat file2 >> bigfile, etc. The uses of this command are wide and very helpful; a great way to work with large amounts of files (also avoids the parameter list is too long message when trying to grep more than 1024 files)
