How to copy an executing script from current folder to another by double click

Question

How should we copy an executing script from one folder to the another?

The script content is:

#!/bin/sh

zenity --forms --title="Add Friend" \
    --text="Enter information about your friend." \
    --separator="," \
    --add-entry="First Name" \
    --add-entry="Family Name" \
    --add-entry="Email" \
    --add-calendar="Birthday" >> addr.csv

case $? in
    0)
        echo "Friend added.";;
    1)
        echo "No friend added."
    ;;
    -1)
        echo "An unexpected error has occurred."
    ;;
esac

Lets say i have saved the above script as test.sh in home/user/Documents/sh/ and when I execute test.sh by double click it should copy itself to the meow folder home/user/wow/meow/.

Answer 1

I'm not sure why you'd want to do this, but you can handle this slightly more elegantly than a raw copy.

mkdir -p $HOME/wow/meow
cp "$(readlink -f $0)" "$HOME/wow/meow"

• It's using $HOME so we aren't reliant on a hard-coded path (moderately more reliable than the ~ substitution for scripting).
• We check that the target directory exists (and create it if not).
• We get the actual script location rather than relying on a hard-coded path.

Answer 2

Add a line in the script to copy itself:

cp /home/user/Documents/sh/test.sh home/user/wow/meow/
