Animus Wisdom

A friend of mine who is starting up his website hosting biz asked me how I update my Wordpress install. I told him I use a couple of bash scripts I made to update all Wordpress installs at once.

It seems to have helped him quite a bit, so I thought it might also help out somebody else.

update-wordpress.sh:

#!/bin/bash
#
# Wordpress Update
#
# Requires: cpio, find, tar and wget
# By Guillermo Antonio Amaral Bastidas < gamaral@amaral.com.mx >
#

### CONFIGURE ###

declare WORDPRESS_LATEST='http://wordpress.org/latest.tar.gz'
declare TMP_DIR='/tmp'

## DO NOT MODIFY BELOW THIS LINE ##

export PATH='/bin:/usr/bin'

declare CPIO=`which cpio`
declare FIND=`which find`
declare RM=`which rm`
declare TAR=`which tar`
declare TEST=`which test`
declare WGET=`which wget`

declare COMMAND="${1}"
declare DESTINATION="${2}"

if [ -z "${COMMAND}" -o "${COMMAND}" = "HELP" ]; then
    echo "Usage: ${0} [COMMAND] ([DESTINATION])"
    echo "       ${0} FETCH"
    echo "       ${0} UPDATE [PATH_TO_EXISTING_WORDPRESS_INSTALL]"
    echo
    exit 0;
elif [ "${COMMAND}" = "FETCH" ]; then
    ${WGET} -q -nv -O "${TMP_DIR}/wordpress.tar.gz" 'http://wordpress.org/latest.tar.gz'
    ${RM} -Rf "${TMP_DIR}/wordpress/"
    ${TAR} -xpszf "${TMP_DIR}/wordpress.tar.gz" -C"${TMP_DIR}"
elif [ "${COMMAND}" = "UPDATE" ]; then
    if [ -z "${DESTINATION}" ]; then
        echo "Usage: ${0} UPDATE [PATH_TO_EXISTING_WORDPRESS_INSTALL]"
        echo
        exit 1;
    fi

    ${TEST} -d "${DESTINATION}";
    if [ $? -ne 0 ]; then
        echo "Destination directory does not exist."
        echo "Abort"
        echo
        exit 2;
    fi

    ${TEST} -d "${TMP_DIR}/wordpress/";
    if [ $? -ne 0 ]; then
        bash ${0} FETCH

        if [ $? -ne 0 ]; then
            echo 'Latest Wordpress Fetch Failed.'
            echo 'Abort'
            echo
            exit 3;
        fi
    fi

    ( cd ${TMP_DIR}/wordpress/ && ${FIND} . | ${CPIO} -up --quiet "${DESTINATION}" )
    if [ $? -ne 0 ]; then
        echo 'Copy Failed'
        echo
        exit 1;
    fi
fi

exit 0;

How it works:

$ update-wordpress.sh FETCH
Downloads and expands the latest release of Wordpress.

$ update-wordpress.sh UPDATE PATH TO WORDPRESS INSTALL
Updates the specified Wordpress install.

Multiple Installs:

I use this tiny script to update multiple installs:

#!/bin/bash

update-wordpress.sh FETCH
update-wordpress.sh UPDATE /var/www/somesite.com/blog/htdocs
update-wordpress.sh UPDATE /var/www/yoursite.org/www/htdocs

Cheers,
