awk - user function?
Here's a snippit from a script I'm working on

Code:
srvctl config database | \
awk -F\" '{print "srvctl config database -d " $1 " -a" \
         RS "echo =================================================="}' \
    > /tmp/x$$.sh
chmod 777 /tmp/x$$.sh
/tmp/x$$.sh

As you can see, I'm piping the output of' 'srvctl' to awk, where I construct other commands that get written to a file, then execute that file. It occurs that I should be able to eliminate that intermediate file and execute the commands directly from awk, but after struggling with some of the on-line tutorials as well as my trusty Unix in a Nutshell, I'm coming up dry. Here's my latest attempt ...

Code:
srvctl config database | \
awk -F\" 'function rptcfg(dbsid) {srvctl config database -d dbsid -a} \
          {print rptcfg($1) \
           RS "echo =================================================="}'

But it only produces a blank line for each of the (2) results from the 'srvctl' command:

Code:
echo ==================================================

echo ==================================================

you may try with system function in awk.

Closer, but it appears that it is trying to do that in a secondary environment that does not inherit the first:

Code:
srvctl config database | \
awk -F\" '{system(srvctl config database -d $1 -a)} \
          {print  \
           RS "echo =================================================="}'

results in
Code:
sh: 00: command not found

echo ==================================================
sh: 00: command not found

echo ==================================================

You might be able to just use xargs.

Something like:
Code:
srvctl config database | awk -F\" '{print $1}' | xargs -I%SUB% echo srvctl config database -d %SUB% -a

The echo is just so you can check if it works first.

You're making this way to hard. If your script above works, the following should work just as well without using the temp file:
Code:
srvctl config database |
awk -F\" '{print "srvctl config database -d " $1 " -a" \
         RS "echo =================================================="}' |
sh

Closer yet. Now how do I get my break line ("==================" back in?

I like the elegance, but that has the same problem as the suggestion from Pamu ..

So run your original script and show us the contents of /tmp/x$$.sh when it is working.

What operating system are you using. (I.e., what is the output from the command uname -a).
