awk problem when attributing query to a variable
Hello,

I'm trying to make a script which reads the PID of a process using awk. I've read the thread in this forum where it is explained.
However, the problem i'm having is when attributing that PID value to a variable.
I'm using AIX 5.3.

The command is the following:
:/home/user1>ps -ef | grep xellerate | grep -i java | awk '{ print $2 }'
958598

Which as you can see.. works.

The problem i'm having is when I try to execute a script which is the following:

#!/bin/ksh
pid=""
pid='ps -ef && grep xellerate && grep -i java && awk '{print $2}''
echo $pid

:/home/user1> ./watchdog2
./watchdog2[3]: }: not found.

:/home/ias1013> pid='ps -ef && grep xellerate && grep -i java && awk '{print $2}''
/bin/ksh: }: not found.

AWK is not doing what I want it to.
Does anyone have any ideas why?

Thanks in advance,
Mambo

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
