.BI \-o " FILE"
Send standard output to named file. In bulk mode, percpu files will
start with FILE_ (FILE_cpu with -F) followed by the cpu number.
-This supports a subset of strftime(3) (%%, %C, %Y, %y, %m, %d, %e, %F,
-%H, %I, %j, %l, %M, %S, %R, %T, %u, %w) for FILE.
+This supports strftime(3) formats for FILE.
.TP
.BI \-c " CMD"
Start the probes, run CMD, and exit when CMD finishes.
.B \-o FILE
Send output to FILE. If the module uses bulk mode, the output will
be in percpu files FILE_x(FILE_cpux in backgroud and bulk mode)
-where 'x' is the cpu number. This supports a subset of strftime(3)
-(%%, %C, %Y, %y, %m, %d, %e, %F, %H, %I, %j, %l, %M, %S, %R, %T, %u, %w)
