my problem is read didnt expect user input.exit status comes 1 what might be the reason??
i tried with correct syntax as u give.But its not working as expected.
As noted in your earlier thread Bash vs shell, if you don't give us anything but "its not working as expected", we can't guess at what (if anything) is wrong. As I requested in the previous thread, please show us:
the entire contents of your shell script (not just this function),
the results of executing the script using the command:
Code:
/bin/sh -xv YourScriptName [argument...]
where YourScriptName is the name of the file containing your script and argument... is the list of arguments you passed to your script (if there were any),
the input you provided when running your script (if there was any), and
the output you expected when running your script.
Am I correct in assuming that you are still using a Solaris SunOS release 5.10 system?
In your last thread you said that you thought the problem might have been a for statement or a variable assignment (neither of which appear in this function) that were causing your problem. How did you determine that they (as opposed to the error function above) were not the problem in your script? If you didn't run the script with tracing as I suggested before, what makes you think that the function above, the for statement, or the variable assignment is the problem rather than something else in your script that you haven't shown us?
I understand this question probably poses some child like stupidity, but I can't get this if statement to work for love or money.

return
exit(1) User Commands exit(1)NAME
exit, return, goto - shell built-in functions to enable the execution of the shell to advance beyond its sequence of steps
SYNOPSIS
sh
exit [n]
return [n]
csh
exit [ ( expr )]
goto label
ksh
*exit [n]
*return [n]
DESCRIPTION
sh
exit will cause the calling shell or shell script to exit with the exit status specified by n. If n is omitted the exit status is that of
the last command executed (an EOF will also cause the shell to exit.)
return causes a function to exit with the return value specified by n. If n is omitted, the return status is that of the last command exe-
cuted.
csh
exit will cause the calling shell or shell script to exit, either with the value of the status variable or with the value specified by the
expression expr.
The goto built-in uses a specified label as a search string amongst commands. The shell rewinds its input as much as possible and searches
for a line of the form label: possibly preceded by space or tab characters. Execution continues after the indicated line. It is an error to
jump to a label that occurs between a while or for built-in command and its corresponding end.
ksh
exit will cause the calling shell or shell script to exit with the exit status specified by n. The value will be the least significant 8
bits of the specified status. If n is omitted then the exit status is that of the last command executed. When exit occurs when executing
a trap, the last command refers to the command that executed before the trap was invoked. An end-of-file will also cause the shell to exit
except for a shell which has the ignoreeof option (See set below) turned on.
return causes a shell function or '.' script to return to the invoking script with the return status specified by n. The value will be the
least significant 8 bits of the specified status. If n is omitted then the return status is that of the last command executed. If return
is invoked while not in a function or a '.' script, then it is the same as an exit.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
