Perhaps a dos2unix or something similiar in Mac.

For your original script
Code:
#!/bin/bash

# Set the video directory here
VIDEO_ROOT_DIRECTORY="/Users/astrid/NFS/scripts/img2iso/";

# Check if the directory exist or not
if [ -d "$VIDEO_ROOT_DIRECTORY" ]; then
  cd $VIDEO_ROOT_DIRECTORY
else
  print "ERROR: Unable to reach directory - or it does not exist!";
  exit 1
fi

for imgfile in $(find . -type f -iname "*.img")
do
  if [ ! -f ${imgfile%.img}.iso ] ; then
    mv ${imgfile} "${imgfile%.img}.iso"
    print "[${imgfile} -> ${imgfile%.img}.iso]"
  else
    mv ${imgfile} "${imgfile%.img}-1.iso"
    print "[${imgfile} -> ${imgfile%.img}-1.iso]"
done

exit 0

Not tested tho'.

Considering the initial requirement (recursively mv .img to .iso),
with zsh:

Code:
cd /Users/astrid/NFS/scripts/img2iso/
autoload -U zmv # put it in your .zshrc
zmv -n '(**/)(*).img' '$1$2.iso'

If the result is correct
remove the n flag:

Code:
zmv '(**/)(*).img' '$1$2.iso'

Otherwise:

Code:
find /Users/astrid/NFS/scripts/img2iso -name '*.img' -exec sh -c 'f="${1%.img}.iso"
[ ! -f "$f" ]&&mv "$1" "$f"' - {} \;

With all this help I know I will get it going!
Thank you so much for your attention, it gives a lot of inspiration. I havn't come around to finish the script yet (it's that other life with kids, laundry, office work etc.) but I'll check back when I'm finished, real soon I hope.


By the way, bash seems to be living here:

Code:
$ ls -l /bin/bash
-rwxr-xr-x   1 root  wheel  1068844 Dec 12  2006 /bin/bash


(and the same goes for zsh, nice!)

A bit optimized (without the useless sed), parametric and verbose version:

Code:
test ~ $ cat img2iso.sh
#!/bin/bash

#VIDEO_ROOT_DIRECTORY="/Users/astrid/NFS/scripts/img2iso"
VIDEO_ROOT_DIRECTORY="/home/test/video"

IN_EXT=".img"
OUT_EXT=".iso"

for infile in $(find "$VIDEO_ROOT_DIRECTORY" -name "*${IN_EXT}" -type f)
do
   echo "----------"
   echo "Processing INFILE <$infile>"
   n=0
   exit=""
   suffix=""

   while [ ! "$exit" ]
   do
      newname="${infile%${IN_EXT}}${suffix}${OUT_EXT}"
      if [ ! -f "$newname" ]
      then
         echo "NEW NAME OK! Renaming to <$newname>"
         mv "$infile" "$newname"
         exit="y"
      else
         echo "NEW NAME <$newname> already exists! Incrementing suffix"
         n=$((n+1))
         suffix="-$n"
      fi
   done
done


And the output before and after execution:

Code:
