Bash script for recursive file convertion windows-1251 --> utf-8

convert.sh

#!/bin/bash

# Recursive file convertion windows-1251 --> utf-8
# Place this file in the root of your site, add execute permission and run
# Converts *.php, *.html, *.css, *.js files.
# To add file type by extension, e.g. *.cgi, add '-o -name "*.cgi"' to the find command

find ./ -name "*.php" -o -name "*.html" -o -name "*.css" -o -name "*.js"  -type f |
while read file
do
  echo " $file"
  mv $file $file.icv
  iconv -f WINDOWS-1251 -t UTF-8 $file.icv > $file
  rm -f $file.icv
done

That script is bad. since iconv doesn't detect if file is already UTF-8.

Yes. I too often see something like
Какое унижение для противника!
It's utf8 text converted to utf8 text assuming it was cp1251.

find ./ -name "*.php" -o -name "*.html" -o -name "*.css" -o -name "*.js" -o -name "*.txt"  -type f |
while read file
do
  if ! file -bi $file | grep -q 'utf-8'
  then 
    echo " $file"
    mv "$file" "$file".icv
    iconv -f WINDOWS-1251 -t UTF-8 "$file".icv > "$file"
    rm -f "$file".icv
  fi
done

For many Russian filenames with spaces and etc, and autodetect for codepage, (macos) best for me:
find ./ -name "*.sql" -type f | while read file; do enca -L russian -x UTF-8 "$file"; done;

just a quick note that that would require enca installed (brew install enca) and might fail if, say, a CP-1251 file was incorrectly saved as UTF-8
