Wie kann ich eine Zeichenfolge durch eine zufällige alphanumerische Zeichenfolge ersetzen 48 Zeichen lang mit awk

Question

Derzeit habe ich eine JSON-Datei mit 2400 Ereignissen. Ich versuche den einfachsten Weg zu finden, die Besucheridentität durch eine zufällige alphanumerische Zeichenfolge mit 48 Zeichen zu ersetzen.

Zur Zeit habe ich eine Basisdatei, in der die visitorid wie diese

„visitorid“ sieht: „$ vids“

Ich suche die „$ vids“ mit awk mit einem zufälligen 48 Zeichen aplhanumeric ersetzen String etwas wie folgt aussehen nach

"visitorid": "777048146a3a00a43d480d5a52c00001e007b06600398z82"

Answer 1

Sie eine rando erstellen m String mit sha Hash und auf die erforderliche Größe geschnitten.

r=$(echo $RANDOM | sha256sum); echo ${r:0:48}

Answer 2

OpenSSL ist das beste Werkzeug, um zufällige Zeichenfolgen zu generieren.

vids=$(openssl rand -base64 36); echo $vids 
lTAyBbCNRu5nOQfmzXtbyWGh5YS2hbiarUdcB3kRJ+sFAcSP 

Wenn eine zufällige Zeichenfolge ist ausreichend, um alle 2400 Besucher-IDs zu ersetzen, dann können Sie bequem die zufällige Zeichenfolge zu awk über -v vids="$vids" Option übergeben. Wenn Sie jedoch eine eindeutige Zufallszeichenfolge pro Besucher-ID benötigen, ist awk nicht das beste Werkzeug, um die Aufgabe zu erledigen.
