Top Forums Shell Programming and Scripting How to have my ksh script pause, until something appears in the logs.? Post 302793053 by chatguy on Thursday 11th of April 2013 03:15:26 PM

A better description of what I hope to be doing:
I suppose I should elaborate:

What I'm modifying is a KSH automation script, that's run on demand, for testing a piece of software.

What this KSH script does/need to do: (Step 2)

1) Shutdown, prepare, and restart the software under test (already scripted)

2) Wait for a message (we'll call "DONE!") to appear in /log.txt that says that the MYSQL DB has bound to the RMI/Software.
a. This can take anywhere from 40 seconds to 7+ minutes, depending on DB size..
b. While I can put a 7+ minute delay there, it would be much better if this KSH script continued "as soon as" the "DONE!" message appears in the /log.txt. *This is the challenge.
c. I cannot simply grep the file for "DONE!" in a while loop, because I cannot delete "old/past" logs in this same file that may already contain this word.
d. I also cannot simply check in a while loop for the filesize to change, since other logs are being appended to this same log file during this wait time.

3) Continuing on with already automated tests...


Apologies I wasn't as detailed the first time around!
Thanks so much
