That is a shell function.
Now what your need is more clear.

Well, for dating your files, your case is more simple. Your files can be stored
in a private directory and a script touch and zip them to a public directory, so:

####your script (for zipping) is just:

touch /files/tozip/yourprg-1.0.0/*

/usr/bin/zip < /files/tozip/yourprg-1.0.0 >/your/download/area/yourprg-1.0.0.zip

######

You only need control the condition of only one download per time stamp.

Your php interpreter can run a shell script (I think), as above, or perhaps just:

exec("line 1; line 2");

Sorry, I don't know nothing about php.

That's part of a shell function, written in POSIX shell language. It
could be bash or ksh or one of several other shells.
The function returns if the first argument is empty or isn't the name of
an existing file or directory. $1 should be in double quotes in case it
contains whitespace.

Hi Mop2,

Don't worry Mop2, I don't know nothing about PHP either. :-) The searchable
documentation and examples are fabulous, however, and inspired cut & paste
seems to get one a very long way.

Hmm...what I really need is to write a tiny shell script that can
iteratively work through a set of zip files, expanding, touching and
re-compressing the contents of each. The idea would be to call it with a PHP
command like exec("touchzipfilepayloads zipfile1.zip zipfile2.zip
zipfile3.zip");

I'll have to search for a simple shell script example that illustrates the
control structure required to process a command line specified list of zip
files. Once I have that, it will be a simple matter of substituting my
unzip, touch, zip, rm command sequence.

Gee, I hope the shell program 'zip' works a little better for me when called
from a shell script. Otherwise, I'm no better off. Golly, isn't it a
stimulating exercise, to battle through the maze of possible solutions and
dead-ends, and finally arrive at working result? I'm having too much fun!

Muz.

Does this look rational to anyone?

#!/bin/sh

while [ $# -ge 1 ]; do
unzip ./Secure/$1 -d ./Secure/Temp > /dev/null 2>&1
touch ./Secure/Temp/* > /dev/null 2>&1
zip -j ./Secure/$1 ./Secure/Temp/* > /dev/null 2>&1
rm ./Secure/Temp/* > /dev/null 2>&1
shift
done

exit 0


Called with something like:

../touchzipfilepayloads zipfile1.zip zipfile2.zip zipfile3.zip

Muz.

Looks like it would probably work. I don't know zip very
well.

(How come you are using what is essentially a Windows tool?
Why not tar?)

(> /dev/null 2>&1 instead of that, I use &> /dev/null.)

The thing to do is make some throwaway zip files and the
necessary dirs and test it.
