wget:tldr:b2ec3
The command wget is a command-line utility used to retrieve files from the internet. Here is an explanation of the given command:
wget: This is the command itself, indicating that you want to use the wget utility.
--directory-prefix ${path-to-directory}: This option specifies the directory where you want the downloaded files to be saved. ${path-to-directory} should be replaced with the actual path to the directory on your system.
--input-file ${URLs-txt}: This option tells wget to read a list of URLs from a file called ${URLs-txt} and download them. ${URLs-txt} should be replaced with the actual filename or path to the file containing the list of URLs.
Combining both options, this command tells wget to download the files specified in ${URLs-txt} and save them in the directory specified by ${path-to-directory}.
