aa_bb_032207.txt
aa_bb_cc_10002878.dat

Output:

aa.xml

aa_bb_cc.dat

I would use tr, not sed or awk:
Code:
tr -d '0-9' < FILE > new.txt

Hi Johnson,

The tr command seems to only remove the 0 and 9

instead of getting output like aa.xml....i'm getting...aa_1285_52.xml..

i tried like this

tr -d '_0123456789' < FILE > new.txt

and the above command is able to remove everything mentioned between quotes...

Thanks for ur command...
Kumar

Some versions of tr require the range to be enclosed in brackets. Try this:
Code:
tr -d '[0-9]' < FILE > new.txt
