Unpack zip archive and convert filenames to utf-8 (e.g. if you got zip archive from Windows)

unzip-conv.sh

#! /bin/bash

from=
to=

if [ -z "$1" ]
then
  echo "Error: no arguments"
  exit 0
else
  from="$1"
fi

if [ -z "$2" ]
then
  to=${from%[.]zip}
else
  to="$2"
fi

unzip "$from" -d "$to"
cd "$to"
convmv -r -f cp1252 -t cp850 * --notest && convmv -r -f cp866 -t utf-8 * --notest
cd ..
