Comment or uncomment lines in a file. Default behavior: do the oposite i.e.
if a line is commented - uncomment it, and vice versa. To make sure that the
matched lines will be [un]commented out - run with -[u]c option. If you don't
specify an --output, the original file (<path>) will be overwritten.
Options:
-h, --help show this help message and exit
-c, --comment comment lines [default: False]
-u, --uncomment uncomment lines [default: False]
-a, --all apply to all lines in file; suppresses -l option
[default: False]
-l LINES, --lines=LINES
comma separeted string of line numbers [default: None]
-s IN_PATTERN, --start-pattern=IN_PATTERN
pattern to match against the line before commented
section [default: None]
-e OUT_PATTERN, --end-pattern=OUT_PATTERN
pattern to match against the first line after
commented section [default: None]
-o OUTPUT, --output=OUTPUT
specify a path to output file [default: None]
--symbol=COMMENT_SYMBOL
