Question

I have something like this:

package="com.program.interesting.program.aplication"

I want a script that will create folders like this:

midir com
cd com/
mkdir program
cd program/
...
etc 

But I want to do this automatically, no matter how many folder I’ll have. I guess this is very simple, but I don’t know how to parse a string on the shell and I don’t want to read a book, just to solve this.

Thanks

You just need to convert . to / and that is all:

mkdir -p "$(echo $package | tr . /)"

The -p key means that mkdir needs to create all necessary parent directories automatically.

Use "" around the command substitution $() if it is possible that $package can contain spaces inside.

The tr command changes the . symbols in the string to slashes.

e.g.

$ echo com.program.interesting.program.aplication |tr . /
com/program/interesting/program/aplication
