Using GREP to extract variable following a string
Hello,
I'm running calculations and I need to extract a specific number from a output file. So far I've only been able to GREP entire lines containing the string: '1 F=' . I would like to go a step further and extract just the number following '1 F='. The entire line looks like:
1 F= -.13250138E+03 E0= -.13249556E+03 d E =-.174650E-01 mag= 35.2157
The number I would like to extract is in red. Thanks for any help.
