httprobe:tldr:8d8ad
This command is used to perform a task involving the cat
, httprobe
, and https
commands in a Unix/Linux environment. Here's a breakdown of the command:
-
cat ${input_file}
: Thecat
command is used to concatenate and display the contents of a file.${input_file}
is a placeholder for the actual name or path of the input file. So, this part of the command is displaying the contents of the specified input file. -
|
: The pipe symbol (|
) is a command-line operator that connects the standard output (stdout) of one command to the standard input (stdin) of another. In this case, it takes the output of thecat
command and passes it as input to thehttprobe
command. -
httprobe
:httprobe
is a command-line tool used for probing and testing HTTP and HTTPS web servers. It sends HTTP/HTTPS requests to a list of URLs provided as input. -
-p ${https:2222}
: This option is specific to thehttprobe
command. It specifies a port number (2222
) for the HTTPS requests.${https:2222}
is a placeholder for the actual port number. So, in this case, it sets the port to2222
for the HTTPS requests.
To summarize, the command reads the contents of the specified input file using cat
, then uses the httprobe
command to send HTTP/HTTPS requests to the URLs obtained from the file. It sets the port number for the HTTPS requests to 2222
.
