Which utility would be used to change how often a filesystem check is performed on an ext2 filesystem without losing any data stored on that filesystem?

`mod2fs` is not a standard or recognized utility in Linux for modifying filesystem check frequencies.

`fsck` is used to check and repair filesystem integrity, but not to configure how often future checks are performed.

The `tune2fs` command is designed specifically for modifying tunable filesystem parameters, such as the maximum mount count between checks or the time interval for checking, on ext2/ext3/ext4 filesystems without losing data.

`mke2fs` is used to create a new ext2/ext3/ext4 filesystem, an operation that would destroy any existing data on the device.

`fixe2fs` is not a standard or recognized utility in Linux for modifying filesystem parameters.
