Berikut ini adalah cara mengetahui apa saja aplikasi yang sudah kita install di mesin linux kita :
- dpkg -l
Ketika perintah tersebut kita jalankan via terminal maka akan tampil daftar list aplikasi yang sudah diinstall seperti berikut :
root@lenovo-deb:~# dpkg -l
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Tri>
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)

Ketika kita jalankan perintah diatas, maka akan tampil list aplikasi yg sdh kita install dgn tampilan sebagai berikut :
libudfread0/stable,now 1.1.1-1 amd64 [installed,automatic]
libudisks2-0/stable,now 2.9.2-2+deb11u1 amd64 [installed,automatic]

3. Dengan memanfaatkan fitur grep
KIta dapat memanfaatkan fitur grep untuk mengetahui suatu aplikasi apakah sudah terinstall di mesin kita, perintahnya yaitu sbb :
apt –installed list | grep ssh
Ketika perintah tersebut kita jalankan, dan jika aplikasi ssh sdh terinstall di mesin kita, maka akan tampil sbb :
root@lenovo-deb:~# apt --installed list | grep ssh
WARNING: apt does not have a stable CLI interface. Use with caution in sc
ripts.

atau bisa juga dgn perintah berikut :
dpkg -l | grep ssh
Ketika perintah tersebut kita jalankan, dan jika aplikasi ssh sdh terinstall di mesin kita, maka akan tampil sbb :
root@lenovo-deb:~# dpkg -l | grep ssh
