noreturn |
Unix files have a hidden character called 'new line' at the end of every line.
PC files have two hidden characters called 'carriage return' and then 'new line' at the end of every line.
When files are transferred from PC machines to Unix machines, it is often useful to convert the file from the PC format to the Unix format, otherwise commands like 'more', to display the file, and text editors can become confused.
This simple utility removes 'carriage return' characters from such files, converting them from PC format to Unix format text files.
EMBOSS programs can read in both PC and Unix text file formats, so it is not necessary for you to use this utility all of the time.

The output file is identical to the input file, except that any trailing carriage returns have been removed. For most files this will make no difference.
