Full Discussion: Grep final set of parameters from fit.log gnuplot file
Top Forums Shell Programming and Scripting Grep final set of parameters from fit.log gnuplot file Post 302783641 by hanson44 on Wednesday 20th of March 2013 06:19:50 PM

Here's one possible way:

Code:
$cat temp.sh
sed -n "/^Final/,/^correlation/ p" infile > temp1.x # get segments
grep "^[a-z]_[0-9][0-9][0-9][0-9] " temp1.x > temp2.x # get lines
sed "s/.* = \([^ ][^ ]*\) .*/\1/" temp2.x > temp3.x # get numbers
sed "N; N; s/\n/ /g" temp3.x # join lines

$ ./temp.sh
0.497897 0.00459204 1.57077
0.49692 0.00889775 1.57078

If your sed does not support \n, there is bound to be some other simple way to join lines on last step.
