POSIX (works in any compliant Unix shell)

Code:
i=1
for f in *.gif; do 
  echo mv "$f" file$i.gif
  i=$((i+1)) 
done

If you like the result, remove "echo" in the example above to perform the actual renames. The quotes around $f are necessary in case there are difficult file names (for instance with spaces)..

If you want leading zeroes you can replace the mv statement with something like this (4 positions):
Code:
mv "$f" file$(printf "%04d" $i).gif

Thanks for your help.
Code:
# for i in `ls file0*.gif` ; do mv -v $i ${i}_new ; done
`file01.gif' -> `file01.gif_new'
`file02.gif' -> `file02.gif_new'
`file03.gif' -> `file03.gif_new'
