Question

I am currently using the below function

!/bin/bash

#Colour change functions

fnHotlinkG2R()
{
        sed -i 's/#hotlink {height: 200px;width: 200px;background: green;/#hotlink {height: 200px;width: 200px;background: red;/' /var/www/html/style.css
}

Rather than creating multiple difference functions I would like to enter the #hotlink as different every time I call the function from within the script.

I am fairly new to sh scripts and would like some assistance please.

First, the first line should be hash bang #! then followed by the path to the program, not just !.

In bash, you don’t declare parameter for the function. You just take the argument (and check whether it is valid/not empty) and use it. In this case, you may want to take the first argument from the function by $1 and replace #hotlink with it.

sed -i 's/'"$1"' {height: 200px; ...

In the part where the function is called, you can call it as if it is another command, and you will supply the #hotlink argument to the command.

fnHotlinkG2R '#hotlink'
