- This manual page documents the GNU version of t✓to✓ou✓uc✓ch✓h.
- t✓to✓ou✓uc✓ch✓h changes the access and modification times of each
- given file to the current time. Files that do not exist
- are created empty. If the first file name given would be
- a valid argument to the _✓-_✓t option and no timestamp is
- given with any of the _✓-_✓d, _✓-_✓r, or _✓-_✓t options and the _✓-_✓-
- argument is not given, that argument is interpreted as the
- time for the other files instead of as a filename.
-
- If changing both the access and modification times to the
- current time, t✓to✓ou✓uc✓ch✓h can change the timestamps for files
- that the user running it does not own but has write per-
- mission for. Otherwise, the user must own the files.
