5. Ketik ps –eo pid,ppid,%mem,cmd | more dan tekan Enter. Akan menampilkan kolom
PID, PPID dan %MEM. PPID adalah proses ID dari proses parent. %MEM menampilkan
persentasi memory system yang digunakan proses. Jika proses hanya menggunakan
sedikit memory system akan ditampilkan 0.

PERCOBAAN 5 (Mengontrol proses pada shell)
1. Gunakan perintah yes yang mengirim output y yang tidak pernah berhenti
$ yes
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
y
^Cnur@nur-Satellite-L740:~$
2. Belokkan standart output ke /dev/null
$ yes > /dev/null
nur@nur-Satellite-L740:~$ yes > /dev/null
^C
3. Salah satu cara agar perintah yes tetap dijalankan tetapi shell tetap digunakan untuk hal
yang lain dengan meletakkan proses pada background dengan menambahkan karakter &
pada akhir perintah.
$ yes > /dev/null &
nur@nur-Satellite-L740:~$ yes > /dev/null &
[1] 2424
4. Untuk melihat status proses gunakan perintah jobs.
$ jobs
nur@nur-Satellite-L740:~$ jobs
[1]+ Running yes > /dev/null &
5. Untuk menghentikan job, gunakan perintah kill diikuti job number atau PID proses.
Untuk identifikasi job number, diikuti prefix dengan karakter ”%”.
$ kill %<nomor job> contoh : kill %1
nur@nur-Satellite-L740:~$ kill %<nomor job> contoh : kill % 1
bash: nomor: No such file or directory
6. Lihat status job setelah diterminasi
$ jobs
nur@nur-Satellite-L740:~$ jobs
[1]+ Running yes > /dev/null &
PERCOBAAN 6 (Menghentikan dan memulai kembali job)
1. Cara lain meletakkan job pada background dengan memulai job secara normal (pada
foreground), stop job dan memulai lagi pada background
$ yes > /dev/null
nur@nur-Satellite-L740:~$ yes > /dev/null
^Z
[2]+ Stopped yes > /dev/null
2. Untuk restart job pada foreground , gunakan perintah fg.
$ fg
nur@nur-Satellite-L740:~$ fg
yes > /dev/null
^Z
[2]+ Stopped yes > /dev/null
3. Shell akan menampilkan nama perintah yang diletakkan di foreground. Stop job lagi
dengan CtrlZ. Kemudian gunakan perintah bg untuk meletakkan job pada background.
$ bg
nur@nur-Satellite-L740:~$ bg
[2]+ yes > /dev/null &
Job tidak bisa dihentikan dengan CtrlZ karena job berada pada background. Untuk
menghentikannya, letakkan job pada foreground dengan fg dan kemudian hentikan
sementara dengan CtrlZ.
$ fg
nur@nur-Satellite-L740:~$ fg
yes > /dev/null
^Z
[2]+ Stopped yes > /dev/null
4.
5. Apabila ingin menjalankan banyak job dalam satu waktu, letakkan job pada foreground
atau background dengan memberikan job ID
$ fg %2 atau $ %2
$ bg %2
nur@nur-Satellite-L740:~$ fg %2
yes > /dev/null
^Z
[2]+ Stopped yes > /dev/null
nur@nur-Satellite-L740:~$ bg %2
[2]+ yes > /dev/null &
nur@nur-Satellite-L740:~$ bg %2
bash: bg: job 2 already in background
6. ketik fg dan tekan Enter, kemudian dilanjutkan dengan Ctrl Z untuk menghentikan
sementara.
nur@nur-Satellite-L740:~$ fg
yes > /dev/null
^Z
[2]+ Stopped yes > /dev/null
7. Lihat job dengan perintah ps fae dan tekan Enter. Kemudian hentikan proses dengan
perintah kill.
nur@nur-Satellite-L740:~$ ps -fae
