Bash techniques

I've been doing a lot of work in bash lately. I've been speeding up the time taken to create the website basics. Right now I can create a Twitter Bootstrap/Modernizr website with blogs etc within a couple of seconds by calling my bash script. So, below are some techniques I've learned along the way:
Prep-end all slashes in a web address with backslashes
webdir=`echo $webdir | sed s,/,\\\\\\\\\\/,g`
Get the last substring from a string separated by slashes
dbn=${longstring##*/}
Put the contents of a .sql into a database
mysql -u root -p password $dbn < $workingdir"/users.sql"
Change a line within a .ini file
sed -i -e '/DB_NAME =/ s/= .*/= '$dbn'/' config.ini
Hope they help!
