Ho bisogno di trovare i dati binari di test per il comando xxd -ps file , che è alcuni GB o almeno diversi MB.
Attualmente sto usando /usr/bin/telnet , ma non è grande ed eterogeneo tra diversi SO.
Quale file è omogeneo e sufficiente tra i diversi sistemi operativi?
Rispondi dal link di Patrix qui .
Per creare un file binario da 1 GB
dd if=/dev/urandom of=sample.bin bs=64m count=16
