^ Shell scripting


A well-written and comprehensive guide to bash shell scripting:


Simple bash script to back up MYSQL databases to local .sql file, in following figure. Ted noting that script variables are not consistently capitalized, would be better form to capitalize all or none of them. Ted also noting that script could read database user passphrase from a file, a file which could be root-only readable and located in a place different from the script, which is likely to be run as a cron job.


Figure x - shell script to dump MYSQL databases, first draft script: 


#!/bin/bash


DATABASE_LIST="information_schema mysql phpmyadmin wikidb database_1 database_2 database_3 ..."

SERVER_NAME="example_database_server"

user="root"
pass_phrase_for_mysql="database-passphrase"
options_extra="--skip-lock-tables"


response="n"

mode_interactive="n"



echo "shell script starting,"



for database in ${DATABASE_LIST}; 
do echo "backing up $SERVER_NAME database $database . . .";

#    command="mysqldump --databases $database -u$user -p$pass_phrase_for_mysql $options_extra >> au-database-back-up--${database}.sql"
    command="mysqldump --databases $database -u$user -p$pass_phrase_for_mysql $options_extra"
    redirect="au-database-back-up--${database}.sql"

    if [ $mode_interactive = 'y' ]; then

        echo "build command '$command' and database back-up filename'$redirect',"
        echo "full command will be '$command' > '$redirect',"
        echo "trying running this command and redirect? [y/N/q]  yes, no, 'q' to quit"

        read response
        if [ $response = 'Y' -o $response = 'y' ]; then
            ${command} > $redirect
        elif [ $response = 'N' -o $response = 'n' ]; then
            echo "skipping present command . . ."
        elif [ $response = 'Q' -o $response = 'q' ]; then
            echo "stopping script '$0' and exiting."
            break
        fi
        echo

    else

        echo "$0:  backing up database '$database' to file '$redirect' . . ."
        ${command} > $redirect
        ls -l $redirect

    fi

done


echo "done."

exit 0

Wanting to understand and use git better, here are some on-line references to git version control.
