Grep log file
Grep the log file for commands
First we find which commands relax has performed, and separate into the different fitting models
egrep -wi --color 'relax>| model -' LOGFILE.txt > greplogfile.txt
Then we replace instances of relax> with empty, and comment out the model line
sed -i "s/relax> //" greplogfile.txt sed -i "s/relax> //" greplogfile.txt
