file has content.

6,cfg,123

and i want to print the line with the word fgt,crf

This utility provides functionality approximately equivalent to the Unix enscript(1) program. It prints plain text files using a single font. It currently handles tabs and formfeeds, but not backspaces. It will line-wrap when using fixed-pitch fonts. It will also do kern- ing and width adjustment. The default device (-sDEVICE=) and resolution (-r) are as follows: gslp epson 180 gsbj bj10e 180 gsdj deskjet 300 gsdj500 djet500 300 gslj laserjet 300 By default the current date is formatted as the center header.
