Another question
Using whiptail and trying to add a gui wrapper around a shell script I
wrote to add a menu to the update process.
#!/bin/bash
echo "This script MUST be run with root priviledges"
echo
echo "Enter number of the option you would like"
echo
OPTIONS="Update List Upgrade Autoremove Clean Quit"
echo
select opt in $OPTIONS; do
if [ "$opt" = "Update" ] ; then
echo Update
apt update
elif [ "$opt" = "List" ] ; then
echo "List Upgradable package"
apt upgrade
elif [ "$opt" = "Upgrade" ] ; then
echo "Upgrade packages"
apt upgrade -y
elif [ "$opt" = "Autoremove" ] ; then
echo "Autoremove packages"
apt autoremove
elif [ "$opt" = "Clean" ] ; then
echo "Clean Up"
apt clean
elif [ "$opt" = "Quit" ] ; then
echo "Thank you and goodbye"
exit
else
echo "bad option"
fi
done
The above works fine
I am now trying to create a checkbox option menu so that the user can
choose which options are needed then when pressing ok these are executed
in order.
whiptail --title "Check list example" --checklist \
"Choose user's permissions" 20 78 4 \
"NET_OUTBOUND" "Allow connections to other hosts" ON \
"NET_INBOUND" "Allow connections from other hosts" OFF \
"LOCAL_MOUNT" "Allow mounting of local devices" OFF \
"REMOTE_MOUNT" "Allow mounting of remote devices" OFF
I am just struggling to figure out how to :
take the above, if the user chooses say 1,2 and 4 then the commands associated
with those options are executed.
so I could edit the above to say for the first option
"UPDATE" "RUN apt update" OFF \
Then if that option is selected it runs
apt update
So another example I found to try and help me was
#!/bin/bash
DISTROS=$(whiptail --title "Test Checklist Dialog" --checklist \
"Choose preferred Linux distros" 15 40 4 \
"debian" "Venerable Debian" ON \
"ubuntu" "Popular Ubuntu" OFF \
"centos" "Stable CentOS" ON \
"mint" "Rising Star Mint" OFF 3>&1 1>&2 2>&3)
exitstatus=$?
if [ $exitstatus = 0 ]; then
echo "Your favorite distros are:" $DISTROS
else
echo "You chose Cancel."
fi
But I am still confused as to how to actually take each selected option and use
if / else statements to do something with this. I think the issue is I don't
really understand stderr properly or how to capture more than one option.
Been trying different things for about an hour, so can keep trying just not
getting very far.
So far I have come up with the following for what I trying to do. So can add /
remove options to the checklist menu ok.
whiptail --title "Check list example" --checklist \
"Choose user's permissions" 20 40 4 \
"Hello" "Print Hello" OFF \
"Goodbye" "Print Goodbye" OFF \
"CYA" "Print cya" OFF \
CHOICEs=$?
echo $CHOICEs
echo $?
which just outputs for example
"Hello" "Goodbye"0
0
https://en.wikibooks.org/wiki/Bash_Shell_Scripting/Whiptail is sort of useful
for getting menus up but not doing anything with the output, it seems to assume
people know how to do that confidently.
Thanks
Paul
