LineEndings.c
I've been looking for a common UNIX-Linux tool that that easily converts text files between different line-ending conventions. Does such a thing exist? If not, let me offer the following program: it reads files using any of the three common conventions, and converts them to any one of the three that you specify.
* LineEndings -- a simple filter to convert the format of line endings in text files. Call this tool from the command line as follows:
LineEndings format
where format specifies the format to which the line endings are to be converted:
"dos" -- carriage return followed by line feed "mac" -- carriage return only "net" -- carriage return followed by line feed (same as "dos") "unix" -- line feed only
The conversion is done on standard input, and the results are written to standard output. There is no need to specify the input line-ending format, since the program recognizes all three formats on input.
That misses the entire point of a main() function! The main() function is the interface between the startup module...
