Bash random numbers
Hi
I would like to write a BASH function for .bashrc that would reduce the datafile content for a certain amount in a random way. For example, if the file has a 100000 lines I would like to create a new one keeping only 10% of lines but chosen randomly. Could someone help me on this? how to generate random numbers that could be used in BASH I do not mind combinations with grep, awk ect ... just to be usable from .bashrc thanks oliver

You're in the wrong place. You need to be in either "linux help" or "unix help". You'll get more help over there
 *watches mod move it*

To save a further edit, I'll reply again.
Dependent on what OS exactly you are using take a look at /dev/random You should be able to: Code:
cat $var >/dev/urandom And a random number will be in $var for you now. Hope this helps
