| 27 | .SH DESCRIPTION
|
|---|
| 28 | .PP
|
|---|
| 29 | With no options specified, the times of last modification and last access
|
|---|
| 30 | are set to the current time.
|
|---|
| 31 | This command is mostly used to trick
|
|---|
| 32 | .I make
|
|---|
| 33 | into thinking that a file is more recent than it really is.
|
|---|
| 34 | If the file being touched does not exist, it is created, unless the \fB\-c\fR
|
|---|
| 35 | flag is present.
|
|---|
| 36 | .PP
|
|---|
| 37 | The \fB\-a\fR or \fB\-m\fR flag may be used to change only the access or
|
|---|
| 38 | modification time. The \fB\-r\fR or \fB\-t\fR flag may be used to change
|
|---|
| 39 | the times to match the times of another file or to a specified time.
