note pvaldes <p>>I want to replace some words in a file</p> <p>ok</p> <p>>In words are present in whole file. But starting of each line in file is by different word so i am using a file in which first character of line at which i wanna do replacement <i>is written</i></p> <p> mmmh? I wonder how you could have a file with unwritten characters. Do you want to match <i>only</i> the first character?</p> <p>>and along with it replaced word is given ( i name it match file)</p> <p> uh? </p> <p> sorry, I get lost, can't understand what you want to do exactly</p> <p>Could we have a small example with some data</p> 1004447 1004447
