Stop Shepherd
sleep 30
loop : IF (Stop Shepherd = "Shepherd not running")
then Start Shepherd
else loop 3 times ( If 3 attempts fail ... Alarm/email )
wait 30
In this case and as well as in the previous script, why are you exectuting sleep 30 secs. The moment
Code:
sh /root/ams_rc stop_shepherd > /dev/null

command returns, shepherd should have been stopped.

How could you put a loop and check the status of already stopped to "not running" status. It will be true in the first iteration itself.

Please post your requirement with out any code in mind. That will help us understand what you are looking for.

continue(1T)						       Tcl Built-In Commands						      continue(1T)

__________________________________________________________________________________________________________________________________________________

NAME
continue - Skip to the next iteration of a loop SYNOPSIS
continue _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code, which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as the catch command and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 10 except 5: for {set x 0} {$x<10} {incr x} { if {$x == 5} { continue } puts "x is $x" } SEE ALSO
break(1T), for(1T), foreach(1T), return(1T), while(1T) KEYWORDS
continue, iteration, loop ATTRIBUTES
