(Note: the commands will not +actually be executed; however, since +.B e2scrub +needs to run some commands to query the system to determine what +commands would be executed, it still needs to be run as root.) +.TP +\fB-r\fR +Remove the e2scrub snapshot and exit without checking anything. +.TP +\fB-t\fR +Run +.B +fstrim(1) +on the mounted file system if no errors are found. +.TP +\fB-V\fR +Print version information and exit. +.SH EXIT CODE +The exit codes are the same as in +.BR e2fsck (8) +.SH SEE ALSO +.BR e2fsck (8) +.SH AUTHOR +Darrick J.
