How to parse the log file to get useful information using perl or shell?

[robertchen117]

hi all,

I have a very long log file like the below, how could I useful info I
need like this:

sr-204 Tec cache size:
"ls -l C:\Tivoli\lcf\dat\1\LCFNEW\Tmw2k\Tec\cache"
total 1
-rw-rw-rw- 1 0 0 54 Nov 01 23:53
EventServer#opp1_0.dat

Also is get every 3 lines just after every "Tec cache size" including
the "Tec cache size" line.

Or even could I get just include the host name and file size? Like
this:
sr-204 54
sr-207 54
....

The log file like this:

.....
