Ok I got it,but when i ran the script with the changed name of the input file it gave me an error

./script
./script[82]: item: bad number

The change i did in the script is only this

exec < testingdata

The requiremnt is a bot diffrent,i am mentioning the points for you..

# scan the 27 data items to make sure they are numbers
# and remove leading zeros while we are at it

This req is like this---

1... We are not bothered about the leading zeroes ie 01,02,03-------------- In my requirement they all are valid numbers,we should ignore the zeroes only ie 00 where ever they are,they are just for filling purpose dont have any meaning.

2..# note each column with a non-zero--

here leading zero is fine ie 01,02,03----- they are fine.Here i need to check that the colums must have a valid number and if more than that numbers are there then it should be in ascending order,if not the data is ascending order in column it should print that data as an error.

3. There should be 27 entries in a row that is fine but in that there must be exactly 15 numbers leaving all 00.

Your apporoach to the requirement is very correct but just some changes.Rest of the code is fullfilling the requirement.I am new to shell script.

Thanks
Namish

NAME
startfluxbox - start a fluxbox session SYNOPSIS
startfluxbox DESCRIPTION
startfluxbox is a script which runs the file ~/.fluxbox/startup If it doesn't exist it will be generated. startfluxbox should be started from your ~/.xinitrc if you use startx, or ~/.xsession if you run a display manager, like xdm. FILES
~/.fluxbox/startup This file contains all commands that should be executed before fluxbox is started. The initial file contains helpful comments for beginners. It also starts fluxbox. EXAMPLES
The default ~/.fluxbox/startup is as follows: #!/bin/sh # # fluxbox startup-script: # # Lines starting with a '#' are ignored. # Change your keymap: xmodmap "$HOME/.Xmodmap" # Applications you want to run with fluxbox. # MAKE SURE THAT APPS THAT KEEP RUNNING HAVE AN ''&'' AT THE END. # # unclutter -idle 2 & # wmnd & # wmsmixer -w & # idesk & # And last but not least we start fluxbox. # Because it is the last app you have to run it with ''exec'' before it. exec fluxbox # or if you want to keep a log: # exec fluxbox -log "$fluxdir/log" If you need to start applications after fluxbox, you can change the exec fluxbox line above to something like this: exec fluxbox & fbpid=$! sleep 1 { xsetroot -cursor_name left_ptr -fg white -bg black & ipager & gkrellm2 & } & wait $fbpid So xsetroot, ipager, and gkrellm2 will all be started after fluxbox, after giving fluxbox 1 second to startup. For more details on what else you can do in this script, see sh(1), or the documentation for your shell. AUTHORS
