Re: Merci à Monsieur Sanchis

Je sais pas sur quelle version tu as essayé sur 4.1 :

root@Workstation:/# bash --version
GNU bash, version 4.1.5(1)-release (x86_64-pc-linux-gnu)
Copyright (C) 2009 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

root@Workstation:/# help typeset
typeset: typeset [-aAfFilrtux] [-p] name[=value] ...
 Set variable values and attributes.
 Obsolete. See `help declare'.
root@Workstation:/# help declare
declare: declare [-aAfFilrtux] [-p] [name[=value] ...]
 Set variable values and attributes.
 Declare variables and give them attributes. If no NAMEs are given,
 display the attributes and values of all variables.
 Options:
 -f restrict action or display to function names and definitions
 -F restrict display to function names only (plus line number and
 source file when debugging)
 -p display the attributes and value of each NAME
 Options which set attributes:
 -a to make NAMEs indexed arrays (if supported)
 -A to make NAMEs associative arrays (if supported)
 -i to make NAMEs have the `integer' attribute
 -l to convert NAMEs to lower case on assignment
 -r to make NAMEs readonly
 -t to make NAMEs have the `trace' attribute
 -u to convert NAMEs to upper case on assignment
 -x to make NAMEs export
 Using `+' instead of `-' turns off the given attribute.
 Variables with the integer attribute have arithmetic evaluation (see
 the `let' command) performed when the variable is assigned a value.
 When used in a function, `declare' makes NAMEs local, as with the `local'
 command.
 Exit Status:
 Returns success unless an invalid option is supplied or an error occurs.
