Need help making a start/stop script...

i have two separate scripts that work nicely to curl and generate two files.. one html and one txt so a total of four.

When the script starts up i want it to:
call and run shellscripta
call and run shellscriptb
sleep for about 40 seconds
again run shellscripta
again run shellscriptb
check and make sure both txta and txtb exist then..
check for any differences..
if they are the same than continue loop/sleep
if the two text files contain different data
email user@somewhere.com with the data of both files then continue loop
--loop stops when i run 'xcommand stop'


There are two parts of this that's difficult for me.. one is creating a loop that starts and stops when i tell it.. the other is the portion that checks for differences then emails.. the script has to 'head -n4' both text files to see if there are any differences.. if there are i need it to 'mail' me both parts of the text files 'head -n5' (5th line containing the date so i know what's oldvsnew).. i hope i'm making some sense but any help would be great

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
See attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWTcl | +--------------------+-----------------+ |Interface Stability | Uncommitted | +--------------------+-----------------+ NOTES
