Hi,
I want to display a menu then I wrote :

while [1]
do
echo "                         Enter your choice"
done

myscript.sh[7]: [1]:  not found

drop the brackets...
i.e.

while 1

while [1]

while [ 1 ];
do
echo " Enter your choice"
done

Pay attention to semicolon and spaces between the brackets

Thank you.
But

while [ 1 ];
select menu_list in "choix 1"  "choix 2"  "fin"
do
	case $menu_list in
		"choix 1").... ;;
    		"choix 2")... ;;
		"fin") exit 0 ;;
		"") echo "$REPLY invalide option  "
	esac
done
done

.sh[7]: syntax error at line 7 : `while' unmatched

while [ 1 ]
do
     

done

while :
do

done 

# or
while true
do

done

thanks to all.
