A little script for my mom's new cell -- explaining just didn't work :) "suoneria" is the italian word for "ringtone"

suoneria

#! /bin/sh
# Original msgs edited or stripped (they were in italian);
# iirc knoppix localizes sell scripts, I don't care.


zdie() {
    zenity --error --text="$*" --no-markup
    exit 123
}

set -e  # 99% of all shell scripts just **assume** things work...
song="$(zenity --file-selection)"
test -s "$song" || zdie "$song???"
start="$(zenity --text "from" --entry-text 0    --entry)"
end="$(zenity   --text "to"   --entry-text 1:23 --entry)"
i=0
BASE="${song##*/}"  # basename
while [ $i -lt 12345 ] ; do
    # - 'z' to line up cleanly separated from other files;
    # - force mp3, my mom's cellphone doesn't grok .ogg;
    # This breaks on windows because of ':' in filenames.
    output="z$i $BASE $start $end".mp3
    i=$(($i + 1))
    if [ -e "$output" ] ; then
        continue
    fi
    sox "$song" "$output" trim "$start" "$end" && exit
done
