httprobe:tldr:e29d6
This command is composed of two parts: cat ${input_file}
and httprobe --prefer-https
.
-
cat ${input_file}
: This uses thecat
command to read the contents of a file specified by the${input_file}
variable. Thecat
command is used to concatenate and display the contents of files. In this case, it is used to read the contents of the file referenced by the${input_file}
variable. -
httprobe --prefer-https
: This is a separate command,httprobe
, which is a tool used for quickly checking the availability of HTTP and HTTPS URLs. The--prefer-https
option is used to prioritize HTTPS URL requests over HTTP. This means that if both HTTP and HTTPS versions of a URL are available, thehttprobe
tool will select the HTTPS version to probe.
To summarize, the given command takes the contents of a file specified by the ${input_file}
variable, passes it as input to the httprobe
command, and checks the availability of HTTP and HTTPS URLs, preferring HTTPS when both are available.
