Melanjutkan Kurang diketahui seri, artikel keempat seri ini akan memberi tahu Anda beberapa berguna lucu Dan animasi perintah. Di sini kita masuk ke sesi praktis, tanpa banyak teori.
10 perintah efektif yang kurang diketahui - 11 Perintah Linux yang Berguna Kurang Diketahui - Bagian I
- 10 Perintah Linux yang kurang dikenal - Bagian 2
- 10 perintah yang kurang diketahui untuk Linux - Bagian 3
- 10 Perintah Linux yang Berguna Kurang Diketahui Bagian V
Dalam artikel keempat dari seri ini yang mencakup beberapa perintah Linux yang kurang dikenal lainnya, layak diketahui. Mungkin Anda sudah mengetahui perintah ini, tidak diragukan lagi Anda adalah pengguna Linux yang berpengalaman dan suka eksplorasi.
32. Perintah Strace
Itu strace adalah alat debugging yang digunakan terutama untuk tujuan pemecahan masalah di Linux. Itu mungkin tidak diinstal secara default di sistem Anda dan Anda mungkin perlu tepat atau yum paket yang diperlukan.

33. Dissown -A && Exit Command
Sebagian besar administrator sistem menggunakan perintah layar untuk mengontrol pekerjaan yang berjalan di latar belakang terminal. Katakanlah jika Anda memiliki pekerjaan yang lama dan ingin melepaskan Dari terminal, Anda menggunakan layar Perintah untuk melakukannya. Tetapi bagaimana jika Anda tidak tahu cara menggunakan layar, inilah perintah yang disangkal untuk diselamatkan.
Perintah Disownel digunakan untuk menjalankan pekerjaan terus menerus di latar belakang bahkan setelah Anda menutup sesi terminal. Sintaks dari perintah Disowning adalah:
[email dilindungi] [~]# perintah; Dissown -A && keluar
Untuk melepaskan lagi pekerjaan yang sudah lama berjalan di terminal, gunakan pekerjaan Perintah untuk menemukan nomor pekerjaan dan kemudian gunakan Disownel %N Di mana N adalah nomor pekerjaan. Untuk memverifikasi sebenarnya pekerjaan berjalan menggunakan ps atau perintah teratas. Itu Nohup Perintah adalah alternatif dari perintah Disown.
