Re: 20050125: pqact.conf syntax - piping...or exec

Steve,

I continue to have problems getting the script to execute.  I have 
modified my pqact.gempak to look like this per your suggestion earlier...

NEXRAD    ^SDUS[2357]. KOAX 
([0-3][0-9])([0-2][0-9])([0-6][0-9]).*/p(N0R|N0V)
   EXEC    /home/dan/exec.csh

For the sake of speed, I chose a site that was operating (OAX) as 
opposed to EAX's, which has been down all day.  The script, 
/home/dan/exec.csh is not executed when N0R or N0V data comes in.  
Again, exec.csh simply renames a file, from before.txt to after.txt.  
Quite a useless program, but it works for testing purposes.

What could I still be doing wrong?

Steve,

Please disregard previous email - problem was within the script - works 
fine now - apologies for the unnecessary email.
