Double grep and replacing
Hi All,

I need to replace a match with are new values when there is a double match.


Code:
grep 04422494 MAX.dat | grep 1102300131

I need to replace 1102300131 as 1101600131 in MAX.dat only for the record matching 04422494 . I tried replace as

Code:
sed/s/1102300131 /1101600131 /g MAX.dat

but it replace all records including 04422494 and other records.


Can you please help

Thanks
Arun

Try:

Code:
sed 's/^\(0004422494\)1102300131/\11101600131/' file

or, a less accurate but maybe good enough:
Code:
sed '/04422494/s/1102300131/1101600131/' file
