thanks KlashXX and Franklin for your suggestion. but unfortunatley I can't use perl in my case .
and I found Frankling sugesstion working for all type of files .

By the mean time I tried below option

Code:
echo $name | awk -F'[^0-9]' '{  for(i=1;i<=NF;++i) if($i ~ /[[:digit:]]/) print $i}'

which is also works for almost all the conditions except if the filename is
xpnl_hypo_reu_miplvdone_11-17-2011.csv i.e if in any characters are in between then o/p is
Code:
11
17
2011

can anyone suggest how to improve this liner.I don't care if any - removed between number but atleast it should be numeral in one line not line after another.

anyway can anyone suggest how to validate the date o/p please??
