Seri Belajar UNIX
Jilid 2 Revisi 1.00
Perintah Dasar Linux/UNIX
Oleh : CyberBug - Kecoak Elektronik
http://www.k-elektronik.org
email : cyberbug@k-elektronik.org
===========================================================================
SEBELUM SAYA DIBOM :
1. Yang saya lakukan disini hanya mengumpulkan resource yang saya rasa
berguna buat yang ingin belajar UNIX, jadi kalo ada yang merasa sudah
pernah membaca apa yang saya tulis ini, SELAMAT!, berarti anda tidak
perlu capek2 membaca tulisan2 berikutnya :)
2. Saya menggunakan Linux untuk mencoba perintah2 jadi ini bisa juga
dianggap sebagai kumpulan perintah dasar Linux
3. Kalau ada yang merasa bisa menulis lebih baik, silahkan buat tulisan
anda dan kirimkan ke webmaster@k-elektronik.org
4. Kritik dan Saran sangat diharapkan untuk perbaikan tulisan ini.
===========================================================================
------> who
who digunakan untuk menampilkan user yang login ke system, hasilnya
kira-kira sebagai berikut :
cyberservices:~$ who
root tty1 Dec 20 17:47
cyberbug tty2 Dec 20 17:48
cyberbug tty3 Dec 20 17:48
cyberbug ttyp0 Dec 20 18:43 (localhost)
Kolom pertama menunjukkan nama user yang login, kolom kedua menunjukkan
terminal line yang digunakan, kolom ketiga menunjukkan waktu login dan
kolom keempat menunjukkan domain atau IP asal mereka koneksi, jika kosong
berarti mereka main langsung dari console.
------> whoami
Kalo lupa diri :) ini perintahnya : Siapakah Aku?
cyberservices:~$ whoami
cyberbug
------> who am i
Ini juga kalo sudah lupa daratan :))
cyberservices:~$ who am i
cyberservices!cyberbug tty3 Dec 20 17:48
------> pwd
Tampilkan directory aktif, pwd = print working directory, perintah yang
dipakai kalo saat jalan2, sudah gak tau mo pulang lewat mana :)
cyberservices:~$ pwd
/home/cyberbug
------> ps
Menampilkan proses yang aktif
cyberservices:~$ ps
PID TTY STAT TIME COMMAND
87 2 S 0:00 -bash
88 3 S 0:00 -bash
1440 2 S 0:00 pico jilid2.txt
1443 3 R 0:00 ps
------> ping
Mengecek host apakah 'up' utk istilah teknisnya silakan 'man ping'
cyberservices:~$ ping localhost
PING localhost (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.2 ms
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=3 ttl=64 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=4 ttl=64 time=0.1 ms
--- localhost ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 0.1/0.1/0.2 ms
cyberservices:~$ ping 127.0.0.1
PING 127.0.0.1 (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.2 ms
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=3 ttl=64 time=0.1 ms
64 bytes from 127.0.0.1: icmp_seq=4 ttl=64 time=0.1 ms
--- 127.0.0.1 ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 0.1/0.1/0.2 ms
cyberservices:~$
Perhatikan bahwa localhost dan 127.0.0.1 adalah sama :)
127.0.0.1 adalah local loopback yang disediakan untuk testing.
