Fact:
I have a server implementaion in Java and running on Solaris platform.
That server generates continously all logs for events, exceptions and
informations in a flat text file.

Design idea:
I like to implement a parser programme (say, process A), written in C,
which will intermittently parse that generated log file and look for
"exception". Once any "exception" is encountered (parsed) by process A,
I like to send a SIGPIPE signal to another programme (say, process B,
also written in C).

Once process B receieves the SIGPIPE signal from process A, I'll
generate a message of occurance of the exception on the console screen.

Question:
1) Is this possible in Solaris unix ?

It could be done with a shell script. Something like this:

tail -f flat.text.file | grep -i exception | awk '{ system("pkill -PIPE
process_B_written_in_C") }'
