read -n1 -r -p "Press..." key / produces error in bash shell script
Hello!

Sorry, for my not so perfect english!

I want to stop bash shell script execution until any key is pressed.

This line in a bash shell script

Code:
read -n1 -r -p "Press any key to continue..." key

produces this error

Quote:
read: 1: Illegal option -n
When I run this from the command line

Code:
usera@lynx:~$ read -n1 -r -p "Press any key to continue..." key
usera@lynx:~$

it works without error.

What do I wrong?
