If you look closely, you'll see that the character before "username", "surname", "address", "startdate", "req", and "options" is a <hyphen> or <minus-sign>, but the character before "debug" is wider. It is what Unicode calls an <en-dash>. If we feed that line through od and look at it as octal bytes and characters we can easily see the difference:

Note that I marked the last hyphen and the en-dash in red in the od output. Each of the hyphens is a single byte with octal value 055 while the en-dash is three bytes with the octal values 342, 200, and 223, respectively.
When you give ksh an en-dash as an input character, it will give it back you you as an en-dash (and not convert it to a hyphen). If you want a the string -debug with a hypen to be assigned to OPTS, give ksh a command line argument containing -debug with a hypen; not -debug with an en-dash.

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 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.
