What command can be used on an existing (formatted) partition, to configure the interval between disk checks when mounting partitions?

`e2fsckconfig` is not a standard command; `e2fsck` is the utility that performs the disk check but doesn't configure its interval.

The `tune2fs` command allows an administrator to adjust various tunable parameters on ext2, ext3, or ext4 filesystems. This includes setting the maximum mount count (`-c`) or the time interval (`-i`) after which `e2fsck` will automatically check the filesystem when it is next mounted.

`mke2fs` is used to create a new ext2/ext3/ext4 filesystem, not to modify parameters of an already existing one.

`config2fs` is not a standard Linux command for configuring filesystem parameters.

`e2fsck` is the utility that checks and repairs an ext2/ext3/ext4 filesystem, but it does not configure the automatic check intervals.
