Try out multitail. This is an übergeneralization of
tail -f
. You can watch multiple files in separate windows, highlight lines based on their content, and more.multitail -c /path/to/log
The colors are configurable. If the default color scheme doesn't work for you, write your own in the config file. For example, call
multitail -cS amir_log /path/to/log
with the following~/.multitailrc
:colorscheme:amir_log
cs_re:green:INFO
cs_re:red:SEVERE
Another solution, if you're on a server where it's inconvenient to install non-standard tools, is to combine
tail -f
with sed or awk to add color selection control sequences. This requires tail -f
to flush its standard output without delay even when its standard output is a pipe, I don't know if all implementations do this.tail -f /path/to/log | awk '
/INFO/ {print "\033[32m" $0 "\033[39m"}
/SEVERE/ {print "\033[31m" $0 "\033[39m"}
'
Yet another possibility is to run
tail -f
in an Emacs shell buffer and use Emacs's syntax coloring abilities.
