Change encoding of all files in folder on Unix, Linux or MacOS

Here is some simple bash script to bulk change encoding of all files in directory. It uses iconv for change of encoding.

#!/bin/bash

if [ $# -ne 3 ]; then
echo “usage: “$0″ dest_directory original_encoding destination_encoding”
exit
fi;

dir=$1
from=$2
to=$3

if [ ! -d $dir ]; then
mkdir $dir
fi

for f in $( ls . ); do
if [ -f $f ]; then
iconv -f $from -t $to $f > $dir$f
fi
done

To run it, create a file recode.sh and paste above code into it. Then in terminal run

chmod +x recode.sh

adn then just

./recode.sh encoded_dir/ ISO-8859-13 UTF-8

Command mentioned above recodes all files in current directory from  ISO-8859-13 encoding to UTF-8 and copies new files to encoded_dir/ directory.
