33. Verweigerung des Befehls -A && Beenden
Die meisten Systemadministratoren verwenden den Bildschirmbefehl, um Jobs zu steuern, die im Terminalhintergrund ausgeführt werden. Nehmen wir an, wenn Sie einen langjährigen Job haben und wollen ablösen Vom Terminal verwenden Sie Bildschirm Befehl, es zu tun. Aber was ist, wenn Sie nicht wissen, wie man den Bildschirm benutzt.
Der Befehl disuner wird verwendet, um die Jobs kontinuierlich im Hintergrund auszuführen, auch nachdem Sie die Terminalsitzung geschlossen haben. Die Syntax des Ableitungsbefehls lautet:
[E -Mail geschützt] [~]# Befehl; Ablehnen -a && Beenden
Verwenden Sie die Arbeitsplätze Befehl, um die Jobnummer zu finden und dann die Ablehnung zu verwenden %N Wo N ist die Jobnummer. Um zu überprüfen, ob der Job verwendet wird, wird verwendet ps oder Top -Befehl. Der nohup Der Befehl ist eine Alternative zum Ableitungsbefehl.
34. GetConf long_bitsbefehl
Der obige Befehl zeigt Ihre Maschinenarchitektur an, wenn dies der Fall ist 32 bit oder 64 Bit?
[E -Mail geschützt] [~]# getconf long_bit 32
Laden Sie das Linux -Befehlszeilen -Cheat -Blatt herunter
35. Datum des Terminals anzeigen
Der folgende Befehl ist eine Kombination mehrerer Befehle. Sagen Sie besser ein Skript. Für eine Person, die am Shell oder am Terminal arbeitet, ohne die GUI zu sehen, ist das aktuelle Systemdatum eine mühsame Aufgabe. Sie müssen tippen 'Datum'Befehl, das heutige Datum zu überprüfen.
Führen Sie einfach den folgenden Befehl auf Ihre Eingabeaufforderung aus und sehen Sie die Datum Und Zeit in der obigen rechten Ecke des Terminals.
[E-Mail geschützt] [~]# Während Schlaf 1; tun TPUT SC; TPUT CUP 0 $ (($ (TPUT COLS)) -29); Datum; TPUT RC; DETED &
Datum im Terminal anzeigen 36. Befehl konvertieren
Während beim Schreiben von Tutorial muss ich normalerweise die Ausgabe erzeugen, oft im Bildformat. Die obige Befehlskombination tut dies für mich. Sagen Sie, ich brauche die Ausgabe des Baumbefehls (für /etc/x11 Verzeichnis) im Bildformat. Was ich am Terminal getan habe, war:
[E -Mail geschützt]:/etc/x11# Baum | Etikett konvertieren:@-/home/avi/tree.png
Die Ausgabe des obigen Befehls ist am angegebenen Ort (hier, Home -Verzeichnis von mir) mit dem angegebenen Dateinamen zu sehen Baum.png.
37. Watch -t -n1 "Datum +%t | Figlet"
Denken Sie an unsere Beschreibung von “Figlet"Befehl in unserem früheren Artikel" 20 lustige Befehle von Linux ". Dieser Befehl war sehr cool, diesmal werden wir pipelinieren 'Figlet'um animierte digitale Uhr im Terminal zu zeigen.
Schauen Sie sich einfach selbst an, denken Sie daran, dass Sie haben müssen Figlet auf dem System installiert, tun Sie geeignet oder Yum So installieren Sie das erforderliche Paket.
