clamscan:tldr:4577f
This command is essentially running two separate commands in sequence, with the output of the first command being used as input for the second command.
The ${command}
portion is a placeholder for whatever the actual command or series of commands you want to run. It could be any valid shell command, or even a shell script.
The |
character is known as the "pipe" operator in Unix-like systems. It allows you to redirect the standard output (STDOUT) of one command to the standard input (STDIN) of another command.
And finally, clamscan -
is the second command being run. In this case, it is the clamscan command, which is a popular open-source antivirus software for UNIX-like systems. The -
indicates that clamscan should read its input from the STDIN, which is being piped from the previous command.
To summarize, the command sequence ${command} | clamscan -
takes the output of ${command}
and redirects it as input to the clamscan command for scanning.
