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
