ABSTRACT

The module identifies the terminal which the logged in user is using currently. For this purpose, the login shell and the logged-in users are determined. The Perl script runs in a pseudo terminal shell with its own identification number. This pseudo terminal shell is also identified. Based on this data, the terminal emulator used can be determined.
