FIXED Re: script to find files owned by particular user and replace with another uid

[Craig White]

Following up on this weeks question, I ended up using JT's script,
modifying it for the fact that I am using LDAP and therefore, no usable
values in /etc/passwd for me and yes, there was a debug issue, and
finally hoping that it handled some typical filename/folder name issues
- borrowing from Darrin's suggestion. Below is my final script for
anyone who wants to track this...

(btw - getent passwd | grep is universal whereas grep /etc/passwd is
useful for only 1 particular situation)

Thanks JT, Darrin, JD, Kurt (I love this list)

#!/bin/sh

USER1=$1
USER2=$2
MYPATH=$3

usage()
{
  echo "Script to change ownership of files from user X to user Y"
  echo "$0 <user1> <user2> [path to search]"
  echo
}

echo "Changing files owned by "$USER1
echo "to user "$USER2
echo "In directory "$MYPATH
echo ""

if [ -z "$USER1" ] ; then echo "Invalid user 1"; usage ; exit 1; fi
if [ -z "$USER2" ] ; then echo "Invalid user 2"; usage ; exit 1; fi
if [ -z "$MYPATH" ] ; then echo "Invalid path" ; usage ; exit 1; fi

UID1=`getent passwd |grep $USER1 | awk -F: '{print $3;}' `
UID2=`getent passwd |grep $USER2 | awk -F: '{print $3;}' `

if [ -z "$UID1" ] ; then echo "Invalid user 1"; usage ; exit 1; fi
if [ -z "$UID2" ] ; then echo "Invalid user 2"; usage ; exit 1; fi

find $MYPATH -user $UID1 -exec chown $USER2 {} \;
