Bash script

Hello,
I need help with bash script. This script must browse directory tree and every file include directories rename from UPPER to lower case.

#! /bin/sh
find $1 -print | while read x ;
do
mv $x $(echo $x | tr 'A-Z' 'a-z')
done

I use this script, but it rename files and directories only in actual directory.

Thank You.

find

find - search a folder hierarchy for files that meet a desired criteria

SYNTAX
find [path...] [expression]

DESCRIPTION
find searches the directory tree rooted at each given file name
by evaluating the given expression from left to right,
according to the rules of precedence (see section OPERA_
TORS), until the outcome is known (the left hand side is
false for and operations, true for or), at which point
find moves on to the next file name.

The first argument that begins with
- ( ) , or !
is taken to be the beginning of the expression; any
arguments before it are paths to search, and any arguments
after it are the rest of the expression. If no paths are
given, the current directory is used. If no expression is
given, the expression `-print' is used.

find exits with status 0 if all files are processed suc_
cessfully, greater than 0 if errors occur.

you did not specify a particular $PATH to use as explained in RED........so it only stays in the current directory

What are you supplying as an argument to the script? Which are you doing:
./scriptname
./scriptname /path/to/directory

If you're doing the first one then $1 in your script is null.

This thread is somewhat similar:
http://www.linuxquestions.org/questions/history/212607

You could use this:

Code:

#!/bin/bash
IFS=$'\n'
find $* -depth | while read x; do
        base=`basename "$x"`
        new=`echo $base | tr A-Z a-z`
        [ "$new" != "$base" ] && mv "$x" "$(dirname "$x")/$new"
done

If you don't give it arguments, it uses the current directory. Have fun!
