Bugtraq: Re: IFS

[rthomas () pamd cig mot com (robert owen thomas)]

hello, David--

IFS: internal field separator.  used by the shell to delimit fields.  by
default, IFS is set to equal three things: tab, newline, and space.  by
manipulating this shell environment variable, commands can have odd (or
even dangerous) results.

suggestion:  pick up the Kochan and Wood shell programming book.

hope this helps!

regards,
--robert
