i have been making a GUI for my Bash script using Glade. Is there anyway i can convert the .glade file to a executable file for Linux?
You can't.
Glade (or GtkBuilder) are just descriptions of the UI, which gets parsed by a (in C with Gtk3) GtkBuilder
object which in turn creates your widgets according UI xml description at runtime. It does not generate any (with the exception for some callback/model-view connections) application logic.
