Project Title

C application for replacing strings within a file

Purpose

This is a C language application for replacing strings within a file, using a simple command line utility called "replace",

ex: replace OPT <from> <to> -- <filename> [<filename>]*

where OPT can be zero or more of -b, -f, -l, -i

• 0: if specified, the replace utility performs the search for string from in a case sensitive way.

• -b: if specified, the replace utility creates a backup copy of each file on which a replace operation is performed before modifying it.

• -f: if specified, the replace utility only replaces the first occurrence of string from in each file.

• -l: if specified, the replace utility only replaces the last occurrence of string from in each file.

• -i: if specified, the replace utility performs the search for string from in a case insensitive way.

• from: string to be replaced with string to.

• to: string that will replace string from.

• filename: the file(s) on which the replace operation has to be performed.
