The command "gcal ${2} ${2010}" is using the "gcal" command to display a calendar for a specific month and year.
In this command, "${2}" and "${2010}" are variables that indicate which month and year to display.
The first variable "${2}" represents the month, and it is possible that this variable refers to the second command-line argument provided when executing the script or command. For example, if the command is executed as "gcal 7 2010", then "${2}" will be replaced by "7" to indicate the 7th month (July).
The second variable "${2010}" represents the year and is assumed to be the value "2010" in this case.
Overall, the command will generate a calendar for the month of July in the year 2010.
