sh and csh issue


I like to assign a command string to a variable to execute.
In this case,

set sshexec_parent_pid="ps -ef | grep $$ | awk '/bash -c/ {print $3}' | sort | head -1;`"
echo $sshexec_parent_pid ;

But I can't seem to get it to work.
It gives me
sshexec_parent_pid: Undefined variable.

Originally, my sh looks like this and this works
sshexec_parent_pid=`ps -ef | grep $$| awk '/bash -c/ {print $3}' | sort | head -1;`
export sshexec_parent_pid ;
echo $sshexec_parent_pid ;

Does anyone know how to do that in csh ?

Advance thanks

why is there a backtik at the end of this line before the last double-quote?

set sshexec_parent_pid="ps -ef | grep $$ | awk '/bash -c/ {print $3}' | sort | head -1;`"

could that be causing a problem if it is in your real code?

Use eval to delay sbustitution of commands

$  test='\`echo "test worked"\`'
$ echo $test
\`echo "test worked"\`
$  test='echo "test worked"'
$  eval $test
test worked
