+Force an ETA newline for every `time` period passed.

Turn on safety read-only checks, preventing any attempted write.

Instead of running the jobs locally, send and run them on the given host.

+Report cpu idleness on a system or percpu basis (\fIoption\fP=system,percpu) or run unit work calibration only (\fIoption\fP=calibrate).
.SH "JOB FILE FORMAT"
Job files are in `ini' format. They consist of one or more
job definitions, which begin with a job name in square brackets and
reserved name, meaning stdin or stdout, depending on the read/write direction
set.
.TP
+.BI filename_format \fR=\fPstr
+If sharing multiple files between jobs, it is usually necessary to have
+fio generate the exact names that you want. By default, fio will name a file
+based on the default file format specification of
+\fBjobname.jobnumber.filenumber\fP. With this option, that can be
+customized. Fio will recognize and replace the following keywords in this
+string:
+.RS
+.RS
+.TP
+.B $jobname
+The name of the worker thread or process.
+.TP
+.B $jobnum
+The incremental number of the worker thread or process.
+.TP
+.B $filenum
+The incremental number of the file for that worker thread or process.
+.RE
+.P
+To have dependent jobs share a set of files, this option can be set to
+have fio generate filenames that are shared between the two. For instance,
+if \fBtestfiles.$filenum\fR is specified, file number 4 for any job will
+be named \fBtestfiles.4\fR. The default of \fB$jobname.$jobnum.$filenum\fR
+will be used if no other format specifier is given.

.BI lockfile \fR=\fPstr
Fio defaults to not locking any files before it does IO to them. If a file or
file descriptor is shared, fio can serialize IO to that file to make the end
Read-write locking on the file. Many readers may access the file at the same
time, but writes get exclusive access.
.RE
-.P
-The option may be post-fixed with a lock batch number. If set, then each
-thread/process may do that amount of IOs to the file before giving up the lock.
-Since lock acquisition is expensive, batching the lock/unlocks will speed up IO.

.BI opendir \fR=\fPstr
manufacturers like to use 10^3 or 1000 as a base ten unit instead, for obvious
reasons. Allow values are 1024 or 1000, with 1024 being the default.
.TP
+.BI unified_rw_reporting \fR=\fPbool
+Fio normally reports statistics on a per data direction basis, meaning that
+read, write, and trim are accounted and reported separately. If this option is
+set, the fio will sum the results and report them as "mixed" instead.
+.TP
.BI randrepeat \fR=\fPbool
Seed the random number generator in a predictable way so results are repeatable
across runs. Default: true.
.TP
.BI lockmem \fR=\fPint
Pin the specified amount of memory with \fBmlock\fR\|(2). Can be used to
-simulate a smaller amount of memory.

Before running the job, execute the specified command with \fBsystem\fR\|(3).
