guru help needed for script

[Anthony khan]

Hi All,

I wrote a script for backup, what the script is doing right now is if any arguments is missing It will exit, but since another program calling this script I don't want the to exit at any stage, rather i'll wait and the input. If the tape is not there it give a message and wait till the some put the tape in the drive and script is keep running in a loop. Can anyone put light here

Anthony,

take this code:

# Checking if device is given

if [ -z "$DEVICE" ]
then
echo $MESSAGE1
echo $MESSAGE2
exit 1
else
mt -t "$DEVICE" rew
fi

if [ $? -ne 0 ]
then
echo "There is no tape"
else
echo " Tape is loaded."
fi



and replace it with this:
##############################
# Checking if device is given

if [ -z "$DEVICE" ]
then
echo $MESSAGE1
echo $MESSAGE2
exit 1
fi

mt -t "$DEVICE" rew
TAPEISLOADED=$?

while [ "$TAPEISLOADED" != "0" ]
do
echo "There is no tape"
# send an email here to notify someone
sleep 60
mt -t "$DEVICE" rew
TAPEISLOADED=$?
done

echo " Tape is loaded."

##############################

Hi Anthony. Maybe this will work. As you check to see wether or not each required element is present or not run each required element through a loop check. I will try to give an example:
# Checking to see if device is given
if [ -z "$DEVICE" ]
then
echo "Please enter valid device name."
echo "Press Enter when done."
read answer1
else
mt -t "$DEVICE" rew
fi

Something like this, if the parameter is not entered, prompt the user and the script will wait for their reply before continuing.

hi try this,

if [ -z "$DEVICE" ]
then
echo "Check Device name/insert the tape and press any key when ready"
read accept
else
mt -t "$DEVICE" rew
fi
