expect: Execute an expect script from a file.
$ expect ${filename}
try on your machine
The command "expect ${filename}" is a command using the expect tool or framework.
The expect tool is a scripting language that provides a way to automate interactive applications such as Telnet, FTP, SSH, etc. It allows you to script interactions with these applications by expecting specific patterns or strings and sending responses accordingly.
In this command, the expect keyword is used to start an expect script. "${filename}" is a variable that holds the name of a file. The script will use this variable to perform some actions on the file.
The exact behavior of the command will depend on the contents of the expect script and how it interacts with the file specified by the ${filename} variable.
