Sorry but I don't know what you're looking for exactly. Entering the following command in a terminal
yields this output:
tune2fs 1.42.13 (17-May-2015)
Usage: tune2fs [-c max_mounts_count] [-e errors_behavior] [-g group]
[-i interval[d|m|w]] [-j] [-J journal_options] [-l]
[-m reserved_blocks_percent] [-o [^]mount_options[,...]] [-p mmp_update_interval]
[-r reserved_blocks_count] [-u user] [-C mount_count] [-L volume_label]
[-M last_mounted_dir] [-O [^]feature[,...]]
[-E extended-option[,...]] [-T last_check_time] [-U UUID]
[ -I new_inode_size ] device
Do you require anything more than this?
Issuing the command
gives you even more detailed information about the tune2fs command. Is there anything in particular you're looking for? Try being as concrete as possible and provide some examples.
