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?

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
