dict:tldr:1993e
The command "dict ${word}" is used to look up the definition or meaning of a word using a dictionary.
Here's a breakdown of each part of the command:
-
dict: This is the command or function being invoked. It represents the action of looking up a word in a dictionary.
-
${word}: This is a placeholder or variable. The curly braces and dollar sign indicate that the value will be dynamically substituted when the command is executed. In this case, ${word} represents the actual word you want to look up.
So, when you run this command in a suitable environment (such as a terminal, programming language, or scripting context), the value of ${word} will be replaced with the word you want to search, and the command will look up the definition of that word in a dictionary.
