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.

Hi,
i want to sum all nubers in one column. Example:

script
SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-adfpqr] [-c command] [file]
DESCRIPTION
script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive
session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
Option:
-a Append the output to file or typescript, retaining the prior contents.
-c command
Run the named command instead of the shell. Useful for capturing the output of a program that behaves differently when associated
with a tty.
-d When playing back a session with the -p flag, don't sleep between records when playing back a timestamped session.
-f Flush output after each write. This is useful for watching the script output in real time.
-p Play back a session recorded with the -r flag in real time.
-q Be quiet, and don't output started and ended lines.
-r Record a session with input, output, and timestamping.
The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. script works best with commands that do not manipulate
the screen, the results are meant to emulate a hardcopy terminal.
ENVIRONMENT
The following environment variable is used by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
script places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
