Thank you Don Cragun and Aia for your reply. That's exactly what I was looking for.

@Don Cragun - My actual file list looks like this:

Code:
 sample-test~1.lg.15-05-25_20:41:05.20150611
 sample-test~1.lg.*
 sample-test~1.lg.15-05-27_20:28:32.20150611
 sample-test~1.lg.15-05-26_20:29:40.20150611
 sample-test~1.lg.20160431.lg
 sample-test~1.lg.20150301.lg
 sample-file~df_gp~1.lg.20150616
 sample-test~1.lg.20150616
 sample-test~1.lg.15-05-28_20:28:27.20150616
 sample-test~1.lg.15-05-27_20:28:32.20150616
 sample-test~1.lg.15-05-26_20:29:40.20150616
 sample-test~1.lg.15-05-25_20:41:05.20150616
 sample-bat-test~1.lg.20150616

So, inline with the example given by you, I managed to filter out the ones with timestamp by using ls -1 sample* | grep -v '[:]' and obtained the below:

Code:
sample-bat-test~1.lg.20150616
sample-test~1.lg.*
sample-test~1.lg.20150301.lg
sample-test~1.lg.20150616
sample-test~1.lg.20160431.lg
sample-file~df_gp~1.lg.20150616

I want to create empty files of all the ones without a timestamp so tried doing this but doesn't seem to work:

Code:
for fn in `ls -1 sample* | grep -v '[:]'`
do
touch fn
done

Could you please tell me where I've gone wrong?
