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?

Dan,

Your pattern below is incorrect. It should end with:
   /p(N0R|N0V)

The first 3 letters of the PIL are N0R or N0V, eg
N0REAX or N0VEAX.

The pattern you had was looking for N0R reflectivity from a station N0V.


After that change, the \4 argument would be replaced by either
N0R or N0V (depending on the product. Your csh would then
access this as $1.

To whom...

I am looking to add an entry into my pqact.gempak file which will
execute a script upon receipt of data.  I had written a script to decode
nexrad data as it came in, but was never successful in getting it to run
via pqact.gempak.  It ran fine via crontab though, making me think my
syntax in the pqact file was bad.  To confirm this, I wrote a small
shell script that would simply rename a file in my home directory.  This
worked fine via crontab, but not through pqact.

This is my pqact.gempak entry...

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

Can someone enlighten me on what I might have done wrong in this
situation?  The spacing is correct, i.e. tabs are where they should be,
this email has probably shifted things erroneously.

Also, if i wanted to pass an argument to my script, such as N0R or N0V,
how would I do this?

NEXRAD...
     EXEC /home/dan/rename.csh \4 ?

Any help in this matter would be appreciated.

Thank you,

Dan Leins

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