enum-files and change-ext

[Emanuel Berg]

Hello, I just wrote this. [1]

Is it any good? :)

TIA


enumerate-files () {
    local -a files
    files=($@)

    local number=1

    for f in $files; do
        if [[ -f $f ]]; then
            mv $f ${number}.${f:e}
            number=$(( $number + 1 ))
        else
            no-file-msg $f # http://user.it.uu.se/~embe8573/conf/.zsh/error
        fi
    done
}
alias enum-files=enumerate-files

change-extention () {
    local new_extention=$1
    shift

    local -a files
    files=($@)

    for f in $files; do
        if [[ -f $f ]]; then
            mv $f ${f:r}.$new_extention
        else
            no-file-msg $f
        fi
    done
}

No they are not! "enumerate-files" only works
once, if you then remove some files you can't
run it again... OK, I'm on it...

See also 'zmv' in zshcontrib(1), as well as vidir(1) from moreutils.

This seems to do better... so far.

enumerate-files () {
    local -a files
    files=($@)

    local number=1
    local new_name
    local ext

    for f in $files; do
        if [[ -f $f ]]; then
            ext=${f:e}
            [[ $ext ]] && ext=.$ext
            new_name=$number$ext
            if [[ -f $new_name ]]; then
                files+=($f)
            else
                mv $f $new_name
            fi
