scule

scule is a simple UTF-8 aware program to change the case of text. scule is UTF-8 aware and works correctly with UTF-8. scule is made to be used as part of a pipeline or as the start of a pipeline. When receiving input from stdin, case is a streaming program and will output text as it is received.

Usage

Usage: scule [options] [<file>]

Options:
    -h, --help  display this help and exit
    -u, --upper  convert to upper case 
    -l, --lower  convert to lower case 
    -v, --version  print the version

It can be used like: scule test.txt or echo test | scule.

If you do not specify --upper or --lower, it will default to --lower.

Why scule?

The name scule was chosen because it is the suffix in majuscule and minuscule (meaning upper case and lower case respectively).
