I'm writing a text-based user interface script in bash and this is how far I have gotten.
Now I get the message that there is a syntax error where i have an unexpected }.
it is marked with "# here is the error" in the code.
Why is this a syntax error?
I have the matching { at the beginning of the function file_function.
and if you have any suggestions on how to complete the script you are more than welcome to tell me.
I am a girl who just started to script and to make my own programs.
It's interesting but difficult, please help!
Thanks to all who reads this.
Code:
#!/bin/bash
# a menu based text-user-interface
main_function()

read files
cp -i $files
}
backup_function()
{
echo "Type in the files to copy:"
read files
cp -b $files
}
preserve_function()
{
echo "Type in the files to copy:"
read files
cp -p $files
}
recursive_function()
{
echo "Type in the files to copy:"
read files
cp -r $files
}
echo "Copy files submenu"
echo "1. Interactive copy, answer yes or no (y/n) before doing the copy"
