| Feb 4, 2015 at 9:28 | comment | added | orion | You have a few good solutions below, but my question is simply, is this the best way to solve your problem? It makes sense, if this happens once. If you replace several lines in a longer script, it would make more sense to read the file (if it isn't too big) into an array, modify the array, and write it back at the end. That's because replacing a line in the middle is expensive - the entire file has to be overwritten from that point forward (unless you had fixed-width lines, then you could use dd and simply write over the chosen line in-place). | |
