Shell Programming and Scripting

Hi,

Can you tell me some techniques to capture contents of a temporary file created by a script.
The script runs and creates a file called process.$$, how can I capture the contents being written to the file without making any changes to the script that's creating the temp file. I have no access to the script but know that it creates a file as named previously. Thanks in advance.

Examine the "ps"-output to get the PID of the script running. Then have a look for the file "process.$PID" ("$$" is the processes own PID) and then copy the file found this way when it appears. Build a loop to do so. The following is a sketch:

Code:

typeset file="/some/path/to/process.$PID"

while : ; do
     if [ -r $file ] ; then
          cp "$file" /path/to/mycopy
     fi
done

I hope this helps.

Which O/S are you running ? I would investigate strace on Linux, truss on Solaris or tusc on HP-UX as applications that can trace and dump out the full read/write buffers a given process is using. I hope this helps.

Hi Thanks for the reply.

I'm using HP-UX.
Thanks for the code, I will try it out and let you know how I go.

Thanks.
