Help to replace a pattern with sed or awk


Hello,

I am trying to find the best way to replace a pattern in the below line:

Original Line:

./begintraffic -i eth0 -R radius -c 1000 -w testreport.data -m live -I all

After search & replacement it should look like

./begintraffic -i eth0 -R radius -c 1000 -w /home/test/run/testreport.data -m live -I all


Please note:

1) there may be more than one whitespace character after "-w" and the option can be anywhere in the line.

I am trying with awk, but I am unable to find the right expression to match the pattern.Can anyone please help to get the right pattern matching expression with either sed or awk to achieve this?


/Ramesh

Use the following command:
Quote:
sed 's/testreport.data/\/home\/test\/run\/testreport.data/'

Or to make it a little easier to read:
Code:
sed -r 's@(testreport.data)@/home/test/run/\1@' file
