## 1. Perintah mana yang menampilkan direktori kerja saat ini di terminal Linux?

**Jawaban**

Perintah pwd (print working directory) menampilkan jalur absolut dari direktori saat ini. Ini penting untuk menemukan lokasi dalam struktur pohon file, terutama saat berpindah antara beberapa folder atau dalam skrip bash.

## 2. Bagaimana cara kembali ke direktori induk dari direktori saat ini?

**Jawaban**

Perintah cd .. memungkinkan naik satu level dalam struktur pohon file. Dua titik (..) mewakili direktori induk, sedangkan satu titik (.) mewakili direktori saat ini. Notasi ini bersifat universal di sistem Unix/Linux.

## 3. Perintah mana yang menampilkan file direktori termasuk file tersembunyi?

**Jawaban**

Opsi -a (all) dari perintah ls menampilkan semua file, termasuk file tersembunyi yang dimulai dengan titik. Tanpa opsi ini, file seperti .bashrc, .gitignore atau .env tidak terlihat dalam daftar.
