Return error if - or certain characters are present in a list of strings
I have a list of strings, for example:

Code:
set strLst = "file1 file2 file3 file4"

I want to log an error if some of the fields happen to begin with -, or have characters like ; : ' , ? ] { =

Which means for example setting
Code:
set ierr = 1

Code:
for i in $strLst
> do
> tmp=`(echo $i | grep ^-) || (echo $i | grep "[; : ' , ? { = ]")`
> if [ "x$tmp" != "x" ]; then
> ierr=1
> fi
> done

Okay, I want to simplify on this.

I just want that the entries and alphanumeric.

Want to allow only the following

a-z,A-Z,numbers,spaces and -

---------- Post updated at 08:55 AM ---------- Previous update was at 08:46 AM ----------

I have created code like this

Code:
set errLst = ""
foreach f ($arg_browseFilesLst)
  set cerr = `echo "$f" | grep "[ ; : ' , ? { } $ = ]"`
  set cerr = `echo $f | awk '/^-|=/'`
  if (${%cerr} > 0) then                            # Matches '-' at beginning or '='
    set errLst = "$errLst $f"
    set ierr = 1
  endif
end

But I really am thinking of only allowing alphanumeric strings and punctuation characters, using
Code:
[:alnum:]

and
Code:
[:punct:]

[/CODE] and also not allowing - at the beginning of the string, and the = sign.
