I have to edit a line in place in a jad file.
MIDlet-Version: 0.5.38
should become MIDlet-Version: 0538
I'm having trouble finding the line in the file. If I had the line already, I'd do:
echo 'MIDlet-Version: 0.5.38' | sed s/\\.//g
I tried several variations of:
sed -i 's/\(MIDlet-Version: \)\\.//replace/g' myfile.jad
can somebody tell me what's wrong and how to do it properly?
You want:
sed -i '/MIDlet-Version: /{s/\.//g}' file.jad
This will remove all the periods from file.jad
only on lines containing MIDlet-Version:
and store the changes back to file.jad
