This command is composed of two parts: cat ${input_file} and httprobe --prefer-https.
-
cat ${input_file}: This uses thecatcommand to read the contents of a file specified by the${input_file}variable. Thecatcommand 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-httpsoption is used to prioritize HTTPS URL requests over HTTP. This means that if both HTTP and HTTPS versions of a URL are available, thehttprobetool 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.
