funksen is correct. Per default the shell uses whitespace as field separator. I learned scripting on an IBM mainframe using REXX so i still follow the (there customary) convention of naming throw-away variables "." which works in ksh too. Like this:

Code:

typeset content=""
echo "word1 word2 word3 word4" | read . . content .
print - "$content"

But this sounds like a problem to me:

As far as i remember the maximum line length for a ksh input line is a system constant and is IIRC 4096 or 8192 characters. If your string is more than 5k characters long a command with this string as argument will either already fail due to shell restrictions or at least be in danger of failing if the string grows over time. The error message will be something like "argument list too long" or something such. You might want to redesign the process which leads to such extraordinary long argument lists.

I hope this helps.

NAME

       canadian-english-huge - a list of English words

DESCRIPTION

       /usr/share/dict/canadian-english-huge is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       There  may  be  any  number  of	word lists in /usr/share/dict/.  /etc/dictionaries-common/words is a symbolic link to the currently-chosen
       /usr/share/dict/<language> file.  /usr/share/dict/words is a symbolic link to /etc/dictionaries-common/words, and  is  the  name  by  which
       other  software should refer to the system word list.  See select-default-wordlist(8) for more information, and/or to change the currently-
       chosen word list.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french
       and  /usr/share/dict/danish  contain respectively lists of French and Danish words if they exist.  Such lists should be coded using the ISO
       8859-1 character set encoding.

SEE ALSO

       ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

       The system word list used to be /usr/dict/words.  For compatibility, software should check that location if /usr/share/dict/words does  not
       exist.

AUTHOR

       Word  lists  are  collected and maintained by various authors.  The Debian English word lists are built from the SCOWL (Spell- Checker Ori-
       ented Word Lists) package, whose upstream editor is Kevin Atkinson <kevina@users.sourceforge.net>.
