Can anyone tell me what does the below sed command do?
Value=`grep 'hello world' filename | sed '/^.*=//'`
Correct me if anything is wrong in that command.
Please explain /^.*=/ ..
It searches for 'something=' in each line and removes it if it exists. 'something' can be anything or nothing.
So if a line was 'a=b hello world' it'd turn it to 'b hello world'.
I'm not really sure why it's there.
