Top Forums UNIX for Dummies Questions & Answers Validating fixed length field... Post 35865 by giannicello on Friday 9th of May 2003 05:43:43 PM

I tried the quotes but that didn't do it. I guess no big deal. I found an alternate way of doing it which I'm not totally happy with... but I'm using awk to split the records, attach a delimiter after each field, like a '/' and then process the 'new' file with the delimiter again via the exec/read command. This works but if the user already typed '/' in the file then it might give me some grief which I'll deal with later. In this case any character, '\/|& @#& blanks *', is valid so I have to pick a delimiter that would most likely be least used...

Thanks to everyone for helping out. I know now that the read command always ignores spaces and concatenate contiguous spaces to a single space.

by the way, why doesn't this work given my premise that any of these characters are valid (+-\/ )...?

echo $desc | grep -Eq '^[0-9a-zA-Z+\-\/][0-9a-zA-Z+\-\/][0-9a-zA-Z ]{2,50}$'

The department description gets flagged as soon as it hits this condition.
