|

.SH DESCRIPTION
|

.PP
|

\fIId\fR prints the current uid and gid, both numerically and symbolically.
|
||||
If the effective uid and gid are different from the real ones, all of them
|
||||
are printed.
|
||||
.PP
|
||||
If the \fB\-u\fP or \fB\-g\fP option is specified, then \fBid\fP will print
|
||||
the effective uid or guid number, respectively, on a single line. Combined
|
||||
with either of those options, the \fB\-n\fP option prints the name instead of
|
||||
the number, and the \fB\-r\fP option prints the real instead of the effective
|
||||
uid or gid.

.SH DESCRIPTION
|
||||
.PP
|
||||
With no options specified, the times of last modification and last access
|
||||
are set to the current time.
|
||||
This command is mostly used to trick
|
||||
.I make
|
||||
into thinking that a file is more recent than it really is.
|
||||
If the file being touched does not exist, it is created, unless the \fB\-c\fR
|
||||
flag is present.
|
||||
.PP
|
||||
The \fB\-a\fR or \fB\-m\fR flag may be used to change only the access or
|
||||
modification time. The \fB\-r\fR or \fB\-t\fR flag may be used to change
|
||||
the times to match the times of another file or to a specified time.
