dd: Generate a file of 100 random bytes by using kernel random driver.
$ dd if=/dev/urandom of=${path-to-random_file} bs=${100} count=${1}
try on your machine
The command dd if=/dev/urandom of=${path-to-random_file} bs=${100} count=${1}
is used to create a file with random data.
dd
: The command for copying or converting files and data.if=/dev/urandom
: Specifies the input file, in this case,/dev/urandom
./dev/urandom
is a special file on Unix-like systems that provides an endless stream of pseudorandom numbers.of=${path-to-random_file}
: Specifies the output file, where${path-to-random_file}
is the path and name of the file you want to create.bs=${100}
: Specifies the block size for copying. In this case, the block size is set to100
bytes.count=${1}
: Specifies how many blocks to copy. Here, it is set to1
, so only one block of100
bytes will be copied.
When you execute this command, it will read 100
bytes of random data from /dev/urandom
and write it to the specified output file ${path-to-random_file}
.

never run a command you are not sure if it is safe.
