Being unable to find an actual copy of mod_files.sh, and seeing lots of complaints/bug fix requests for it, here's one that works. It gets all its parameters from PHP.INI, so you don't have the opportunity to mess up:#!/bin/bash## Creates directories for PHP session storage.# Replaces the one that "comes with" PHP, which (a) doesn't always come with it# and (b) doesn't work so great.## This version takes no parameters, and uses the values in PHP.INI (if it# can find it).## Works in OS-X and CentOS (and probably all other) Linux.## Feb '13 by Jeff Levene.[[ $# -gt 0 ]] && echo "$0 requires NO command-line parameters.It gets does whatever is called for in the PHP.INI file (if it can find it)." && exit 1# Find the PHP.INI file, if possible:phpIni=/usr/local/lib/php.ini # Default PHP.INI location[[ ! -f "$phpIni" ]] && phpIni=/etc/php.ini # Secondary location[[ ! -f "$phpIni" ]] && phpIni= # Found it?# Outputs the given (as $1) parameter from the PHP.INI file:# The "empty" brackets have a SPACE and a TAB in them.#PhpConfigParam() { [[ !
