Hi Don,

Basically, the requirement is to process the files in ascending date
Code:
2013.12.13

order, but descending suffix order
Code:
a.log

, and for every date and suffix, we need to check if the file exists and is greater than 0 size. Also, on failure, we need to output an appropriate message.

So far, I have tried this, but does give me expected sorted result, could someone point where I am doing the mistake :

Code:
for file in `cat file.txt | sort -k1,1nr -k2,2 -t _`; do echo $file; done

# Here is the file.txt :

Code:
ski2015.12.15.12.30.23.log
ski2015.12.15.12.30.24_a.log
ski2015.12.15.12.30.25_b.doc
ski2015.12.15.12.30.25_b.doc
ski2015.12.15.12.30.25_b.log
ski2015.12.15.12.30.25_b.log
ski2015.12.15.12.30.25_b.log
ski2015.12.14.12.30.24_a.log
ski2015.12.14.12.30.25_b.doc
ski2015.12.14.12.30.25_b.doc
ski2015.12.14.12.30.13_b.log
ski2015.12.14.12.29.25_b.log
ski2015.12.14.12.30.25_b.log
ski2015.12.14.12.30.23.log
ski2015.12.14.12.29.25_a.log
ski2015.12.15.12.30.23_a.log
ski2015.12.14.12.29.25_b.log
ski2015.12.14.12.29.25_c.log


Thanks.
