I've probably tooted about this before, but I don't know why this isn't standard.

It's just so obvious, at least to me. ;)

~ $ type mcd
mcd is a function
mcd () 
{ 
    [[ -n $1 ]] && mkdir "$1" && cd "$1"
}

Should've made this a long time ago:

function ciglob {
    #case-insensitive glob generator
    echo "$*" |while read -N1 c; do
        case "$c" in
            [a-zA-Z])   echo -n "[${c^^}${c,,}]";;
            *)          echo -n "$c"
        esac
    done
}

~ $ ciglob "Hello, world!"
[Hh][Ee][Ll][Ll][Oo], [Ww][Oo][Rr][Ll][Dd]!
~ $ ls -ld $(ciglob documents)
drwxr-xr-x 52 ~~~ ~~~ 20,480 Apr 10 11:45 Documents

(Not the most useful example, but I did have a use case in mind when I wrote it ;)

P.S. (This is a valid way to close a parenthesis. Fight me ;)
