Hi wisecracker,
Please don't impose your method of performing this task on Nastybutler. Let Nastybutler choose whatever increment he wants. Either of the obvious choices can yield perfectly fine results for this task and as soon as the syntax error is resolved, the logic errors are likely to reveal themselves very quickly. Infinite loops tend to become obvious quickly when there is an echo inside that loop.

As RudiC said in Nastybutler's other thread, if the goal here was to write efficient code, there would be no requirement for a while loop. It appears that the goal of this assignment is to learn how to correctly write a while loop. Whether or not that while loop contains an if statement isn't the point.

With the error that Nastybutler is currently seeing, there are three likely things that could be causing the problem:

A syntax error in the if statement.
A syntax error in the statement before the fi keyword that wasn't fully diagnosed until the fi was seen.
Or, something like a carriage-return in a DOS line terminating <carriage-return><newline> character pair when a single-character <newline> UNIX line terminator was expected on one of the two lines before the fi.

Like you, I'm guessing that the problem is point #2 above, especially since the shell I use complains about an unexpected "(" two lines before the spot that the shell Nastybutler is using complains about something "near the unexpected token `fi'". But, if adding the missing character to line 12 doesn't solve the problem, #3 above becomes a real possibility.

sum

sum(1B) 					     SunOS/BSD Compatibility Package Commands						   sum(1B)

NAME

       sum - calculate a checksum for a file

SYNOPSIS

       /usr/ucb/sum file...

DESCRIPTION

       sum  calculates	and  displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
       look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an  algorithm	which  may
       yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
       been transferred between machines with different-sized ints.

USAGE

       See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWscpu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       sum(1), wc(1), attributes(5), largefile(5)

DIAGNOSTICS

       Read error is indistinguishable from EOF on most devices; check the block count.

NOTES

       sum and /usr/bin/sum (see sum(1)) return different checksums.

       This utility is obsolete.
