You can use the Perl script below (one-liners) can be easily extracted.
If Perl is installed, enter the following command for example.
perl -ne "print if ( /search-string/ )" inputfile.txt > outputfile.txt
"Search-string" is a string that contains the line you want the output (Perl regular expressions can be. Perl regular expressions here ).
"Inputfile.txt" extract the original file, "outputfile.txt" results for the output file.
This alone, "inputfile.txt" from "search-string" and containing the "outputfile.txt" will be written to.
Alternatively, you can not extract the text, if the log file.
csv can also be used when you want to extract only the lines that contain specific strings from a file.
