It's caused when the first character in the options field is a dash. I'm calling the script from the command line. The script was edited using vi. Here's the full output with debug when I use '-options -debug':
And now if I run the same command but remove the dash from before 'debug' in the options field:

Hello all,
I have two files, that I suspect may contain hidden characters (EG, three spaces instead of a tab). Does anyone know of any tool that can display this (I have tried using diff, but I'm not quite sure it would do the job) (6 Replies)
Hello All,
I'm trying to parse through a file and display all the hidden characters, including all carriage and line returns. I usually use cat -v, but this doesn't display the carriage and line returns. Does anyone know how this can be done?
Thanks

Can anyone seem to know how to find out whether a UNIX text file has 'hidden' control characters?
Can I view them using 'vi' by some command line options?
If there are control characters in a text file which are invisible/hidden.. then how do I get rid of them?

I know that cat -v will show me hidden characters in a file....
I for some reason seem to think that there's a bash command that will show me hidden characters in a variable in a script? Or am I just imagining it?

I am completely new to perl programming. My father is helping me learn said programming language. However, I am stuck on one of the assignments he has given me, and I can't find very much help with it via google, either because I have a tiny attention span, or because I can be very very dense.

Hello everyone.

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.
