.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility displays the user and group names and numeric IDs, of the
|
||||||
|
calling process, to the standard output.
|
||||||
|
If the real and effective IDs are different, both are displayed,
|
||||||
|
otherwise only the real ID is displayed.
|
||||||
|
.Pp
|
||||||
|
If a
|
||||||
|
.Ar user
|
||||||
|
(login name or user ID)
|
||||||
|
is specified, the user and group IDs of that user are displayed.
|
||||||
|
In this case, the real and effective IDs are assumed to be the same.
|
||||||
|
.Pp
|
||||||
|
The options are as follows:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl G
|
||||||
|
Display the different group IDs (effective, real and supplementary)
|
||||||
|
as white-space separated numbers, in no particular order.
|
||||||
|
.It Fl g
|
||||||
|
Display the effective group ID as a number.
|
||||||
|
.It Fl n
|
||||||
|
Display the name of the user or group ID for the
|
||||||
|
.Fl G ,
|
||||||
|
.Fl g
|
||||||
|
and
|
||||||
|
.Fl u
|
||||||
|
options instead of the number.
|
||||||
|
If any of the ID numbers cannot be mapped into names, the number will be
|
||||||
|
displayed as usual.
|
||||||
|
.It Fl p
|
||||||
|
Make the output human-readable.
|
||||||
|
If the user name returned by
|
||||||
|
.Xr getlogin 2
|
||||||
|
is different from the login name referenced by the user ID, the name
|
||||||
|
returned by
|
||||||
|
.Xr getlogin 2
|
||||||
|
is displayed, preceded by the keyword ``login''.
|
||||||
|
The user ID as a name is displayed, preceded by the keyword ``uid''.
|
||||||
|
If the effective user ID is different from the real user ID, the real user
|
||||||
|
ID is displayed as a name, preceded by the keyword ``euid''.
|
||||||
|
If the effective group ID is different from the real group ID, the real group
|
||||||
|
ID is displayed as a name, preceded by the keyword ``rgid''.
|
||||||
|
The list of groups to which the user belongs is then displayed as names,
|
||||||
|
preceded by the keyword ``groups''.
|
||||||
|
Each display is on a separate line.
|
||||||
|
.It Fl r
|
||||||
|
Display the real ID for the
|
||||||
|
.Fl g

||||||

||||||
|
options instead of the effective ID.

|
||||||
|
The

|
.Nm
|
||||||
|
utility sets the modification and access times of files to the
|
||||||
|
current time of day.
|
||||||
|
If the file doesn't exist, it is created with default permissions.
|
||||||
|
.Pp
|
||||||
|
The options are as follows:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl a
|
||||||
|
Change the access time of the file.
|
||||||
|
The modification time of the file is not changed unless the
|
||||||
|
.Fl m
|
||||||
|
flag is also specified.
|
||||||
|
.It Fl c
|
||||||
|
Do not create the file if it does not exist.
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|

|
||||||
|
No error messages are displayed and the exit value is not affected.
|
||||||
|
.It Fl m
|
||||||
|
Change the modification time of the file.
|
||||||
|
The access time of the file is not changed unless the
|
||||||
|
.Fl a
|
||||||
|
flag is also specified.
|
||||||
|
.It Fl r Ar file
|
||||||
|
Use the access and modification times from the specified file
|
||||||
|
instead of the current time of day.
|
||||||
|
.It Fl t Ar [[CC]YY]MMDDhhmm[.SS]
|
||||||
|
Change the access and modification times to the specified time.
|
||||||
|
The argument should be in the form
|
||||||
|
.Dq [[CC]YY]MMDDhhmm[.SS]
|
||||||
|
where each pair of letters represents the following:
|
||||||
|
.Pp
|
||||||
|
.Bl -tag -width Ds -compact -offset indent
|
||||||
|
.It Ar CC
|
||||||
|
The first two digits of the year (the century).
|

If
|
||||||
|
.Dq YY
|
||||||
|
is specified, but
|
||||||
|
.Dq CC
|
||||||
|
is not, a value for
|
||||||
|
.Dq YY
|
||||||
|
between 69 and 99 results in a
|
||||||
|
.Dq CC
|
||||||
|
value of 19.
|
||||||
|
Otherwise, a
|
||||||
|
.Dq CC
|
||||||
|
value of 20 is used.
|
||||||
|
.It Ar MM
|
||||||
|
The month of the year, from 1 to 12.
|
||||||
|
.It Ar DD
|
||||||
|
The day of the month, from 1 to 31.
|

||||||
|
.Dq CC
|
||||||
|
and

|
.Dq YY
|
||||||
|
letter pairs are not specified, the values default to the current

year.

.Sh STANDARDS
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility is compliant with the
|
||||||
|
.St -p1003.1-2004
|
||||||
|
specification.
|
||||||
|
.Pp
|
||||||
|
The obsolescent form of
|
||||||
|
.Nm touch ,
|
||||||
|
where a time format is specified as the first argument, is supported.
|
||||||
|
When no
|
||||||
|
.Fl r
|
||||||
|
or
|
||||||
|
.Fl t
|
||||||
|
option is specified, there are at least two arguments, and the first
|
||||||
|
argument is a string of digits either eight or ten characters in length,
|
||||||
|
the first argument is interpreted as a time specification of the form
|
||||||
|
.Dq MMDDhhmm[YY] .
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Dq MM ,
|

|
.Dq DD ,
|
||||||
|
.Dq hh
|
||||||
|
and
|

|
.Dq mm
|
||||||
|
letter pairs are treated as their counterparts specified to the
|
||||||
|
.Fl t
|
||||||
|
option.
|
||||||
|
If the
|
||||||
|
.Dq YY
|
||||||
|
letter pair is in the range 69 to 99, the year is set from 1969 to 1999;
|
||||||
|
otherwise, the year is set in the 21st century.
