Every program is limited by the language which is used to write it. C is a programmer's language. Unlike BASIC or Pascal, C was not written as a teaching aid, but as an implementation language. C is a computer language and a programming tool which has grown popular because programmers like it! It is a tricky language but a masterful one. Sceptics have said that it is a language in which everything which can go wrong does go wrong.

In my second sed article, I offered examples that demonstrated how sed works, but very few of these examples actually did anything particularly useful. In this final sed article, it's time to change that pattern and put sed to good use.

Sed Man Page
Sed Man Page
The sed utility is a stream editor that reads one or more text files, makes editing changes according to a script of editing commands, and writes the results to standard output. The script is obtained from either the script operand string or a combination of the option-arguments from the -e script and -f script_file options.

Sed is affectionally known as a 'Stream Editor' which really means that it takes standard in and routes it out to standard out. Typically all input comes from the file that you are editing where it is splashed onto your screen or redirected to file. The command instructions that do the work tend to be inserted into a script that is read by sed. www.ewalkins.com
