The command git reset ${filename1 filename2 ---} is not a valid git command in its current form.
In git, the git reset command is used to undo changes made to a repository's commit history. It allows you to move the HEAD and the current branch pointer to a different commit, effectively removing or reverting the commits that you specify.
The git reset command can be used in three different modes, which are specified using the --soft, --mixed, or --hard options. However, none of these options are present in the given command.
Additionally, the ${filename1 filename2 ---} syntax is not a recognized git syntax. It seems like the intention might have been to mention specific file names to be reset, but the correct syntax for that would be git reset <filename1> <filename2> ....
Therefore, without more context or information, it is not possible to provide a precise explanation for the given command.
