function::user_char_warn - Linux


function::user_char_warn helps analyze character counts within a text file. It provides warnings and suggestions for improving character usage and readability.


function::user_char_warn [FILE] [OPTIONS]

  • -f, --file: Text file to analyze.
  • -l, --length: Maximum character count. Default: 80
  • -h, --help: Display help and usage information.


Analyze character ‘e’ in a file:

function::user_char_warn -c e -f example.txt

Set maximum character count to 100:

function::user_char_warn -f example.txt -l 100
