 I'd to tear through a library & all my code that used the library and
replace a load of function names that wouldn't clash with another library.

 Here's a handy shell function to do a search & replace on all the files
you send it:

function frep ()
{
    if [ $# -lt 2 ] ; then
        echo "Usage: $0 oldpattern/newpattern [files]"
    else
        old=`echo $1 | cut -d / -f 1`
        new=`echo $1 | cut -d / -f 2`
        shift 1
        echo Replacing $old with $new in $*

    for f in $*
    do
ed - $f << ENDED
g/$old/s//$new/g
w
q
ENDED
    done

    fi
}
