sha256sum:tldr:65093
This command consists of two parts, separated by the pipe symbol (|):
-
${command}
: This is a placeholder that represents a specific command that needs to be executed. You would replace${command}
with the actual command that you want to run. For example, if you want to calculate the SHA256 hash of a file named "myfile.txt", you would replace${command}
with the command that reads the contents of "myfile.txt". -
sha256sum
: This is the command that calculates the SHA256 hash of the data it receives as input. It takes the input data and produces a 64-character hexadecimal string that represents the hash value.
The pipe symbol (|) is known as a "pipe" or "vertical bar" in Unix-like systems. It is used to redirect the output of one command to another command as input. In this command, it takes the output of ${command}
and passes it as input to sha256sum
.
In summary, this command runs the given ${command}
and then calculates the SHA256 hash of the output produced by ${command}
using the sha256sum
command.
