My version of the wc tool, completing the first of John Crickett's Coding Challenges
Install it with pipx:
pipx install willc
Here's a lightly adapted man page! (Since it's built with typer, you can just use the --help option, however!)
NAME
willc – word, line, character, and byte count
SYNOPSIS
willc [-clmw] [file ...]
DESCRIPTION
The willc utility displays the number of lines, words, and bytes contained in each input file, or standard input (if no file is specified) to the standard output. A line is defined as a string of characters delimited by a ⟨newline⟩ character. Characters beyond the final ⟨newline⟩ character will not be included in the line count.
A word is defined as a string of characters delimited by white space characters. White space characters are the set of characters for which the iswspace(3) function returns true. If more than one input file is specified, a line of cumulative counts for all the files is displayed on a separate line after the output for the last file.
The following options are available:
-c: The number of bytes in each input file is written to the standard output. This will cancel out any prior usage of the -m option.
-l: The number of lines in each input file is written to the standard output.
-m: The number of characters in each input file is written to the standard output. If the current locale does not support multibyte characters, this is equivalent to the -c option. This will cancel out any prior usage of the -c option.
-w: The number of words in each input file is written to the standard output.
When an option is specified, willc only reports the information requested by that option. The order of output always takes the form of line, word, byte, and file name. The default action is equivalent to specifying the -c, -l and -w options.
If no files are specified, the standard input is used and no file name is displayed.
