Q: Coinstar point How can I create a file with custom size in linux ?
A:
You can create a file using the dd command in linux
dd if=/dev/zero of=/root/keyfile bs=1M count=1024
This will create a file at /root/keyfile with 1024MB size.
dd if=/dev/urandom of=/root/keyfile bs=1024 count=4
This will create a file with random content with the size of 4096 bits.
