Only a process with appropriate +privileges can increase the limit. +.SH OPTIONS +.LP +The \fIulimit\fP utility shall conform to the Base Definitions volume +of IEEE\ Std\ 1003.1-2001, Section 12.2, Utility Syntax Guidelines. +.LP +The following option shall be supported: +.TP 7 +\fB-f\fP +Set (or report, if no \fIblocks\fP operand is present), the file size +limit in blocks.
