eol copies infile to outfile, replacing every NL (Newline) by CR+NL (Carriage-Return followed by Newline).
NL is end-of-line in Unix text files. CR+NL are end-of-line in MS-DOS and OS/2 text files.
eol is smart enough not to change CR+NL to CR+NL+NL (i.e. detects when the input already has DOS style end-of-lines).
If you don't specify logfile, eol writes error messages to standard error.
eol recognizes the following command line options:
Option | Function |
---|---|
-u2d | Replace every CR+NL by NL. (No, eol does not remove every CR blindly - only when followed by a NL.) |
-d2u | Replace every NL by CR+NL (default). |
-v | Print version banner and usage info to standard error (or logfile, if given), then exit. |
eol returns with one of the following codes ("error levels"):
Code | Meaning |
---|---|
0 | Success |
102 | Incorrect command line arguments |
104 | Error opening file |
105 | I/O error |
107 | File name clash |
