awk
du -ah | awk '$1 > s' s="$filesize" is not working properly. Its only comparing the first digit of the size.

To be honest, I don't know what you are doing wrong. Since I already showed my code is working, here a simple example that Franklin52's code is working too. Instead on depending on du's switches, I used the posted output in an input file:

Code:
root@isau02:/data/transfer> cat infile

$1 is working the 1st field, not the first digit. awk is like that.

Sadly it isnt working even now....and one thing is for sure, it has got nothing to do with du. Because the output i posted was a sample one, not the complete form of du and still the code you gave wasnt working. It's very frustrating Smilie. Have been working on this for more than a day.

Ok, I have a suggestion. Just do that du you are using and post the original output of here piped in a head -20.

Old 01-30-2009
Code:
du -a . | head -20 

output :

Solaris has several flavors of awk. Which version of awk are you using - awk, oawk or nawk? Try using /usr/xpg4/bin/nawk.

Ok, now do this:

Code:
du -a . | head -20 | awk '$1 > 20 {print $1}'

You should get:

Code:
22      ./OMautomation/pvd/062508_040000_wrapper_2.log
22      ./OMautomation/pvd/062608_040000_wrapper_2.log

If not, then I have no clue anymore.
