Also, is it possible to cut this file into chunk. The delimiter would be the "ERROR 123 detected."
Each chunk of file will be put into a new file.
Something like this:

Code:
awk '/ERROR [0-9]* detected/{close(f);f=($4"_"$5"_"++c".out")}f{print>f}' filename

Use nawk on Solaris.

Now, I only want to get a certain part on the file.. say the part

11/16 14:09:50.0868 ---- Sending a <writing> event
11/16 16:10:51.6707 --- Generating a <reading> event

11/16 16:08:19.5436 --- Generating a <reading> event
11/16 16:08:19.7784 ---- Sending a <writing> event

which is after the 2nd "ERROR 123 detected." line. Then put it in a file.

Code:
awk '/ERROR [0-9]* detected/{++c};c==2' filename>second_error.out

Use nawk or /usr/xpg4/bin/awk on Solaris.
