groff: Run a `groff` command with preprocessor and macro options guessed by the `grog` utility.
$ eval "$(grog -T utf8 ${path-to-input-me})"
try on your machine
This command is a way to dynamically evaluate the output of the grog
command with certain arguments and set it as the value of the environment variable. Let's break it down:
eval
: This is a shell command used to evaluate and execute the result of another command."$(...)""
: The double quotes and the$()
syntax are used to capture the output of a command and pass it as a parameter to another command.grog
: This is likely the name of an executable program/utility.-T utf8
: These are command line options/arguments passed to thegrog
command. It specifies the character encoding to use, in this case, UTF-8.${path-to-input-me}
: This is likely a placeholder indicating the path to a specific file thatgrog
should operate on. You would replace${path-to-input-me}
with the actual path to the file you want to use.
So, in summary, the command executes the grog
program with the specified options and filename, captures its output as a string, and then evaluates that string in the current shell environment.

never run a command you are not sure if it is safe.
