ag: Find files containing "foo", and print the line matches in context.
$ ag ${foo}
try on your machine
This command uses the utility "ag" to search for a pattern or string within a file.
The "${foo}" notation is used to reference the value of a variable named "foo". It is typically used in shell scripting languages like Bash. The value of the variable "foo" will be substituted into the command before it is executed.
Therefore, when executing the command "ag ${foo}", the "ag" utility will search for the pattern specified by the value of the variable "foo". The search will be conducted within the files passed as arguments to the "ag" command.
