%highlight '\d+' --color 'bright blue on yellow' *.txt
%head -n20 mail.txt | highlight -l '^Subject:.*'
%highlight --helphighlight [OPTION]... PATTERN [FILE]...
Highlight PATTERN in each FILE or standard input. PATTERN is a perl regular expression.
- -i, --ignore-case
-
Ignore case distinctions.
- -m, --multiline
-
Consider PATTERN as a multiline expression. This will add the '/ms' flags to the Perl regular expression.
- -l, --highlight-line
-
Highlight the entire line instead of just the match.
- -n, --line-number
-
Print line number with output lines.
- -H, --with-filename

Prepend each line with the current file's name.
- -h, --no-filename
-
Suppress the prefixing filename on output.
- -s, --no-messages
-
Suppress error messages about nonexistant or unreadable files.
- --label=LABEL
-
Print LABEL as filename for the standard input.
- -c, --color=COLOR
-
Use COLOR to highlight the matches. COLOR may be expressed either as a human-readable color like "dark blue" or "bold green", or as the numbers in an ANSI escape code (e.g. "31", "1;34;42"). Your terminal may not be able to display all codes.
