How does `type` differ from `which`?

The type and which commands in Linux serve different purposes:

1. type:

   • Provides information about how a command is interpreted by the shell.
   • It can indicate if a command is a built-in shell command, an alias, a function, or an executable file.
   • Example usage:

     type ls

2. which:

   • Locates the executable file associated with a command in the directories listed in the PATH environment variable.
   • It only returns the path of the executable file if it exists.
   • Example usage:

     which ls

In summary, type gives more detailed information about the command's nature, while which simply finds the path of the executable.
