I'm currently tailing some log files so I can watch what's going on with a particular process. What I'd really like to do is to highlight particular matches in the file, preferably with different colours. Does anyone know of any command line applications that could do something like this?

If set up correctly grep will colour matches - the only problem being it will only do one at a time.

Try tailing through 'awk', where you can set up whatever set of matches you want, together with appropriate actions to execute on matching lines. Then a match can output the matching line through some filter which would output it coloured (and non-matching lines can be output "as-is").

If you give us an example of the sort of match you're looking for, with an example of a non-matching line, I (or others) can show how to set it up in 'awk'.

Dunno how to program the colouring, though (but I'm sure others know). Ted.

I have looked at multitail for this in the past, but haven't yet had chance to use it - might be able to do what you are after.

Looks like just the thing, thanks.
