Utility I built to avoid having to clean up ESlint and pylint warnings about trailing white spaces. Creates a new file with _nwts appended to the file name which has no trailing white spaces. Has the option to flag the range of lines to make changes to.

Eg. running $ ./rm_tws remove_trailing_white_spaces.c will result in a remove_trailing_white_spaces_ntws.c file with no trailing white spaces.

Flags

1. --help: will display all the flag options
2. -l/--lines : followed by the range of lines in between (inclusive of the numbers) where the check for white space will be done. Eg. $ ./rm_tws remove_trailing_white_spaces.c -l 1 10 100 200 removes the trailing white spaces between and including lines 1-10 and 100-200. Exits program if odd number of range values is provided. If flag is not present, the all the lines are checked for trailing white spaces.
3. -v/--verbose : utility will print out the line numbers and the number of trailing white spaces found on said line number when flag is present
4. -s/--show : utility will not make the new file but only shows/print out the trailing white spaces in the appropriate range with @.
