I pointed out earlier that // means "global". That makes sense because an empty search would not make sense.
Now RudiC opened my eyes for the /# and /% modifiers. Again, makes sense!

OMG bash-4 comes with even more modifiers:
Code:
 array=( john paul george ringo )
 for btl in ${array[@]}; do echo "$btl"; done 
john
paul
george
ringo
 for btl in ${array[@]^}; do echo "$btl"; done
John
Paul
George
Ringo
 for btl in ${array[@]^^}; do echo "$btl"; done
JOHN
PAUL
GEORGE
RINGO

UNIQUE(8)						      System Manager's Manual							 UNIQUE(8)

NAME
unique - removes duplicates from a wordlist SYNOPSIS
unique output-file DESCRIPTION
This manual page documents briefly the unique command, which is part of the john package. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. john, better known as John the Ripper, is a tool to find weak passwords of users in a server. The unique tool finds and removes duplicate entries from a wordlist (read from stdin), without changing the order. This is important to increase the performance of john when using the wordlist method. SEE ALSO
john(8), mailer(8), unafs(8), unshadow(8). The programs are documented fully by John's documentation, which should be available in /usr/share/doc/john or other location, depending on your system. AUTHOR
This manual page was written by Jordi Mallach <jordi@debian.org>, for the Debian GNU/Linux system (but may be used by others). John the Ripper and mailer were written by Solar Designer <solar@openwall.com>. The complete list of contributors can be found in the CRED- ITS file in the documentation directory. john June 03, 2004 UNIQUE(8)
