p runs processes in parallel and wait for their termination. The processes can be marked to have different colors and the output can be tagged with the processes names (in fact, this is the original main purpose of the script).
An idea for the future, is to have a parameter “-&” to indicate that commands will be separated by &. And wihout it they must be passed by using quotes "process1 arg1" "process2 arg2" (This is the current setting).

p -bc blue "ping 127.0.0.1" -uc red "ping 192.168.0.1" -rc yellow "ping 192.168.1.1" -t example "ping example.com"
Runs 4 ping processes in parallel. The first pinging localhost with output in bold and blue color. The second, 192.168.0.1, underlined with red color. The third reversed with yellow color. The fourth tagged with title example.
p "tail -f /var/log/httpd/access_log" -bc red "tail -f /var/log/httpd/error_log"
Runs two ‘`tail -f’'s in one terminal. One with apache access log, the other with the apache error log highlighted in red.
p tail -f /var/log/httpd/access_log \& -bc red tail -f /var/log/httpd/error_log
or
p tail -f /var/log/httpd/access_log "&" -bc red tail -f /var/log/httpd/error_log
Same command as above written in a different way. This is not currently supported. It is interesting because you can pass a parameter as "blah bleh" which is impossible in the first version in which the space will always be used to separate the parameters. If your shell does not treat & as a special char you can just put it plain on the command line.
p tail -f "some file" \& p tail -f "some other file with space in the name.txt"
An example of the usefullness of & as separator on this command.
p -t project1 "hg pull project1" -t project2 "hg pull project2" -t project3 "hg pull project3"
Pulls 3 mercurial projects simultaneously.

Does not work with title (“-t”) having a slash (“/”). That’ll be corrected on future versions.
