Can you explain the scenario and what you want to redirect?

this will help you to get size of the file:
Code:
ls -l filename | awk '{print $5}'

From man find :
Quote:
-size n[cwbkMG]
File uses n units of space. The following suffixes can be used:

‘b’ for 512-byte blocks (this is the default if no suffix is used)

‘c’ for bytes

‘w’ for two-byte words

‘k’ for Kilobytes (units of 1024 bytes)

‘M’ for Megabytes (units of 1048576 bytes)

‘G’ for Gigabytes (units of 1073741824 bytes)
use find, determine if the file is greater than 5MB and then eventaully copy this file to another, with a different name. HTH, if I got it correctly.

I believe you need to use a "+" in front of the 5M...otherwise it will only look for files exactly 5MB.
