  php-deluxe.net - description Touch Unix
touch is a Computer program on Unix and Unix-like systems used to change a Computer file s date- and time-stamp.
One option makes it possible to set the file s time-stamp to something other than the current system date and time, but this action is normally restricted to the owner of the file or the system s Superuser.
The version of touch bundled in Coreutils that is distributed by the FSF and found on most GNU/Linux systems was written by Paul Rubin, Arnold Robbins, Jim Kingdon, David MacKenzie and Randy Smith.

To many, the name "Unix" conjures up images of a mysterious, cryptic system watched over by a highly paid but surly "Unix guru" in beard and suspenders (it is a myth that persons without facial hair cannot hope to understand Unix).

 Touch (Unix) - Wikipedia, the free encyclopedia
touch is a standard Unix program used to change a file's access and modification timestamps.
It is a Windows version of the touch utility.

 Historia de Unix: Relato evolutivo de Unix
Tague was familiar with Unix and its capabilities and tells the variety of reasons ranging from inadequate file systems, to inadequate performance, to poor user interface that he recommended the initial adoption of Unix to start the work.
Without Unix and its potential portability, the people building the operations support systems were faced with selecting an outside vendor that could supply the hardware on which to get their devlopment done.
Unix, the product of researcher at Bell Labs, the then regulated ATandT system, and academic computer science, and a valuable invention for computer science, for computer education and for the education of the next generation of computer scientists and engineers, is such an event.

 Unix:
Unix was born at Bell Labs out of the aborted attempt to make Multics the most advanced time sharing computer system yet available.
The creation of the Unix operating system was a collaborative effort of many mathematicians and theorists, and much of the success of the project was due to the people involved and the environment in which the system was written.
Unix came into many CS departments largely because it was the only powerful interactive system that could run on the sort of hardware (PDP-11s) that universities could afford in the mid '70s.

 UNIX IN THE ENTERPRISE - All tar files are not created equal
For anyone who has created and extracted from tar files for as many years as I have, the idea that a tar file is a tar file is tar file generally falls into the same mental bin as ftp is ftp and telnet is telnet.
And, while long path names are certainly possible on any Unix system, most tar files have only a few directory levels, thereby reducing the length of path names substantially.
The easiest way is with the touch command (the command should be typed as one line).

These timestamps are changed to the current time, unless the -r option is specified, in which case they are changed to the cor- responding timestamps of the file ref_file, or the -t option is speci- fied, in which case they are changed to the specified time.
GNUDETAILS If the first file 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 file name.
If changing both the access and modification times to the current time, touch can change the timestamps for files that the user running it does not own but has write permission for.

Unix filenames can't have spaces, slashes, or weird characters in them.
The main use of touch is to update the timestamp on a file; if you touch an existing file, it changes the last modification date of that file to now.
These are excellent, no-nonsense guides to Unix, and each includes a reference to Unix shell commands, info on using vi, the C Shell, Bourne shell, programming tools, and much more.

Since filemtime returns a UNIX timestamp, there is no need to call date('U') so the script could be simplified to:
Note: the script to touch a file you don't own will change it's owner so ensure permissions are correct or you could lose access to it
Of course, PHP needs to have write access to the folder containing the file you want to touch, but that should be easy to arrange.

 Tech Tips: November 17, 1998
The UNIX "touch" command offers this functionality, and files that are "touched" have their modification time set to the current time.
This feature is sometimes implemented by reading the first byte of the file and then writing it back, but a cleaner operation is to rely on a system service for this purpose.
With UNIX there is only one root for file-naming purposes, "/".

Turns out that quite a number of users like the new "touch" behavior, but an almost equal number still prefer the previous "hands-off" behavior.

For me, the touch behaviour could be useful sometimes, but far from always.

In Unix, this will only occur when all references to the file are removed.
In a file system where the filename is stored along with the file, the rename operation will change this.
It is not used by Unix, because the filename is not stored with the file but in the directory.
