Some script syntax

[Ngoh Chean Siung]

Hi,

echo "Press [Y]/[y] to continue, [Enter] to quit \c"
read ans rest
if [ -z "$ans" ]
then
exit
fi

Above is part of the script.
1) what is \c for?
2) what is rest for?
3) what is -z for?

regards.

1) Supress return
(Will leave the cursoe after "quit")
2) "Garbage collector".
If user types other words after "y"
3) Test if zero = enter/return

Hi,

1. if you specify \c then the ouput will be like:

Press [Y]/[y] to continue, [Enter] to quit

if \c is not specified then:
Press [Y]/[y] to continue, [Enter] to quit


3. -z is to see whether user simply pressed ENTER key that mean he entered nothing and the string length is zero so it's time quit.

Hope that helps.
