my text file looks like this:
Liquid penetration 95% mass (m) = 0.000205348
Liquid penetration 95% mass (m) = 0.000265725
Liquid penetration 95% mass (m) = 0.000322823
Liquid penetration 95% mass (m) = 0.000376445
Liquid penetration 95% mass (m) = 0.000425341
now I want to delete Liquid penetration 95% mass (m) from my lines to obtain the values only. How should I do it?
If there's only one = sign, you could delete everything before and including = like this:
$ sed -r 's/.* = (.*)/\1/' file
0.000205348
0.000265725
0.000322823
0.000376445
0.000425341
If you want to change the original file, use the -i option after testing:
sed -ri 's/.* = (.*)/\1/' file
-r use ERE so we don't have to escape ( and )s/old/new replace old with new.* any number of any characters(things) save things to backreference later with \1, \2, etc.Collected from the Internet
