Jumping lines in bash script

October 26, 2022

what would goto, translate to in bash script

This is my code:

#!/bin/bash
read distro </etc/issue
echo $distro
if [[ "$distro" = "Debian GNU/Linux bookworm/sid n l" ]];
then
    goto Debian:
elif [[ "$distro" = "Ubuntu GNU/Linux bookworm/sid n l" ]];
then
    goto Ubuntu:
elif [[ "$distro" = "kali GNU/Linux bookworm/sid n l" ]];
then
    goto Kali:
elif [[ "$distro" = "Arch GNU/Linux bookworm/sid n l" ]];
then
    goto Arch:
else
    echo No suported OS detected some thing may not work
fi

Debian:
echo using Debian
sleep 5
exit

Ubuntu:
echo using Ubuntu
sleep 5
exit

Kali:
echo using kali
sleep 5
exit

Arch:
echo using Arch
sleep 5
exit

Its a really simple code and I don’t even know if the way I’m checking the Linux distro will work

I have tried with the Goto function from a batch from windows but it wont work on Linux, how would i jump form line to line

>Solution :

I’d recommend using a Switch-Case statement with fall-through.

All the ‘handlers’ can be defined in a function that will be called from the switch:

#!/bin/bash

handleDebian() {
    echo "Using Debian"
}

handleUbuntu() {
    echo "Using Ubuntu"
}

handleKali() {
    echo "Using Kali"
}

handleArch() {
    echo "Using Arch"
}

handleUnknown() {
   echo "No suported OS detected some thing may not work"
}

read distro </etc/issue
case "$distro" in
    "Debian GNU/Linux bookworm/sid n l")    handleDebian() ;;
    "Ubuntu GNU/Linux bookworm/sid n l")    handleUbuntu() ;;
    "kali GNU/Linux bookworm/sid n l")      handleKali() ;;
    "Arch GNU/Linux bookworm/sid n l" )     handleArch() ;;
    *)  handleUnknown() ;;
esac
