Few years ago after leaving this telecom vendor I was working
with one of my colleagues who was with the application team IMed
me and asked for help to delete a directory with a & at the end.
The command I told him was:
rm -rf dir\&
which in the most bizzare way got translated by him to:
rm -rf dir /&
This would have caused minimal damage had this not been run as root
user and on the main database server with terabytes of data
on it..What happened next is anybody's guess Smilie

NAME
spell - GNU spell, a Unix spell emulator SYNOPSIS
spell [options] files ... DESCRIPTION
This manual page documents briefly the spell command. This manual page was written for the Debian GNU/Linux distribution (but may be used by others), because the original program does not have a manual page. Instead, it has documentation in the GNU Info format; see below. spell is a program that emulates the traditional Unix spell command by calling the Ispell utility. It is a spell checking program which prints each misspelled word on a line of its own. OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options are included below. For a complete description, see the Info files. -I, --ispell-version Print Ispell's version. -V, --version Print the version number. -b, --british Use the British dictionary. -d, --dictionary=FILE Use FILE to look up words. -h, --help Print a summary of the options. -i, --ispell=PROGRAM Calls PROGRAM as Ispell. -D, --ispell-dictionary=DICTIONARY Use the named DICTIONARY to look up words. -l, --all-chains Ignored; for compatibility. -n, --number Print line numbers before lines. -o, --print-file-name Print file names before lines. -s, --stop-list=FILE Ignored; for compatibility. -v, --verbose Print words not literally found. -x, --print-stems Ignored; for compatibility. SEE ALSO
The programs are documented fully by GNU Spell, a clone of Unix `spell', available via the Info system. AUTHOR
