Add Pause Prompt In a Shell Script

Use "read". There is no pause command under bash shell.

#!/bin/bash
echo $1
read -p "Press [Enter] key to continue."
exit 0

The sample script above shows what is entered as a command line parameter and then pauses, waiting for the user to press the ENTER key to continue. This creates a PAUSE.

Require command line parameters

see example:

if [ -z $1 ] || [ -z $2 ] ; then
        echo "newuser: too few arguments"
        echo "Usage: newuser [username] [uid]"
        echo "Adds a new robotz.com customer, for use by admin@robotz.com only."
else
        useradd -r $1 -d /home/$1 -m -n -u $2
fi
exit 0
