Sedname - Batch rename files using sed

Question

Renaming files using sed is nothing new, but this script makes the process a little more friendly and adds a few features, including insertion of sequential numbers and a simulation mode.  The output of any find command can also be piped through sedname.
sedname version 1.0.0
Batch-renames files using a sed script
Usage: sedname [OPTIONS] SEDSCRIPT FILE ...
Usage: find [...] | sedname [OPTIONS] SEDSCRIPT
Example: sedname 's/\(.*\)\.jpg/\1.jpeg/' *.jpg
Example: find /mypics | sedname 's/\(.*\)\.jpg/\1.jpeg/'
OPTIONS:
--sim simulate only
--dir rename directories too
Use #D to insert a number with D digits forming a unique filename
Example: sedname 's/thisname.*/thatname#3/' *
( changes thisname* to thatname001, thatname002, ... )
Use #0 in replacement name to insert a number if needed
Example: sedname 's/thisname.*/thatname#0/' *
( changes thisname* to thatname, thatname1, thatname2, ... )

What does it have over zsh's zmv:
# Remove illegal characters in a fat32 file system. Illegal characters are
# / : ; * ? " < > |
# NOTE: ``-Q'' and (D) is to include hidden files.
$ unwanted='[:;*?\"<>|]'
$ zmv -Q "(**/)(*$~unwanted*)(D)" '$1${2//$~unwanted/}'
# Changing part of a filename (i. e. "file-hell.name" -> "file-heaven.name")
$ zmv '(*)hell(*)' '${1}heaven${2}'
# or
$ zmv '*' '$f:s/hell/heaven/'
# remove round bracket within filenames
# i. e. foo-(bar).avi -> foo-bar.avi
$ zmv '*' '${f//[()]/}'
# serially all files (foo.foo > 1.foo, fnord.foo > 2.foo, ..)
$ ls *
1.c asd.foo bla.foo fnord.foo foo.fnord foo.foo
$ c=1 zmv '*.foo' '$((c++)).foo'
$ ls *
1.c 1.foo 2.foo 3.foo 4.foo foo.fnord
# Rename "file.with.many.dots.txt" by substituting dots (exept for the last
# one!) with a space
$ touch {1..20}-file.with.many.dots.txt
$ zmv '(*.*)(.*)' '${1//./ }$2'
# Remove the first 4 chars from a filename
$ zmv -n '*' '$f[5,-1]' # NOTE: The "5" is NOT a mistake in writing!
# Rename names of all files under the current Dir to lower case, but keep
# dirnames as-is.
$ zmv -Qv '(**/)(*)(.D)' '$1${(L)2}'
# replace all 4th character, which is "1", with "2" and so on
$ zmv '(???)1(???[1-4].txt)' '${1}2${2}'
# Remove the first 15 characters from a string
$ touch 111111111111111{a-z}
$ zmv '*' '$f[16,-1]'
# Replace spaces (any number of them) with a single dash in file names
$ zmv -n '(**/)(* *)' '$1${2//( #-## #| ##)/-}'
# or - with Bash
$ find . -depth -name '* *' -exec bash -c '
> shopt -s extglob
> file=$1
> dir=${file%/*}
> name=${file##*/}
> newname=${name//*([ -]) *([ -])/-}
> mv -i -- "$file" "$Dir/$newname"' {} {} \;
# Clean up file names and remove special characters
$ zmv -n '(**/)(*)' '$1${2//[^A-Za-z0-9._]/_}'
# Add *.py to a bunch of python scripts in a directory (some of them end
# in *.py and give them all a proper extension
$ zmv -n '(**/)(con*)(#qe,file $REPLY | grep "python script",)' '$1$2.py'
# lowercase all extensions (i. e. *.JPG) incl. subfolders
$ zmv '(**/)(*).(#i)jpg' '$1$2.jpg'
# Or - without Zsh
$ find Dir -name '*.[jJ][pP][gG]' -print | while read f
> do
> case $f in

> *) mv "$f" "${f%.*}.jpg" ;
> esac
> done
# remove leading zeros from file extension
$ ls
filename.001 filename.003 filename.005 filename.007 filename.009
filename.002 filename.004 filename.006 filename.008 filename.010
$ zmv '(filename.)0##(?*)' '$1$2'
$ ls
filename.1 filename.10 filename.2 filename.3 filename.4 filename.5 ..
# renumber files.
$ ls *
foo_10.jpg foo_2.jpg foo_3.jpg foo_4.jpg foo_5.jpg foo_6.jpg ..
$ zmv -fQ 'foo_(<0->).jpg(.nOn)' 'foo_$(($1 + 1)).jpg'
$ ls *
foo_10.jpg foo_11.jpg foo_3.jpg foo_4.jpg foo_5.jpg ...
# adding leading zeros to a filename (1.jpg -> 001.jpg, ..
$ zmv '(<1->).jpg' '${(l:3::0:)1}.jpg'
# See above, but now only files with a filename >= 30 chars
$ c=1 zmv "${(l:30-4::?:)}*.foo" '$((c++)).foo'
# Replace spaces in filenames with a underline
$ zmv '* *' '$f:gs/ /_'
# Change the suffix from *.sh to *.pl
$ zmv -W '*.sh' '*.pl'
# Add a "".txt" extension to all the files within ${HOME}
# ``-.'' is to only rename regular files or symlinks to regular files,
# ``D'' is to also rename hidden files (dotfiles))
$ zmv -Q '/home/**/*(D-.)' '$f.txt'
# Or to only rename files that don't have an extension:
$ zmv -Q '/home/**/^?*.*(D-.)' '$f.txt'
# Recursively change filenames with characters ? [ ] / = + < > ; : " , - *
$ chars='[][?=+<>;",*-]'
$ zmv '(**/)(*)' '$1${2//$~chars/%}'
# Removing single quote from filenames (recursively)
$ zmv -Q "(**/)(*'*)(D)" "\$1\${2//'/}"
# When a new file arrives (named file.txt) rename all files in order to
# get (e. g. file119.txt becomes file120.txt, file118.txt becomes
# file119.txt and so on ending with file.txt becoming file1.txt
$ zmv -fQ 'file([0-9]##).txt(On)' 'file$(($1 + 1)).txt'
# lowercase/uppercase all files/directories
$ zmv '(*)' '${(L)1}' # lowercase
$ zmv '(*)' '${(U)1}' # uppercase
# Remove the suffix *.c from all C-Files
$ zmv '(*).c' '$1'
# Uppercase only the first letter of all *.mp3 - files
$ zmv '([a-z])(*).mp3' '${(C)1}$2.mp3'
# Copy the target `README' in same directory as each `Makefile'
$ zmv -C '(**/)Makefile' '${1}README'
# Removing single quote from filenames (recursively)
$ zmv -Q "(**/)(*'*)(D)" "\$1\${2//'/}"
# Rename pic1.jpg, pic2.jpg, .. to pic0001.jpg, pic0002.jpg, ..
$ zmv 'pic(*).jpg' 'pic${(l:4::0:)1}.jpg'
$ zmv '(**/)pic(*).jpg' '$1/pic${(l:4::0:)2}.jpg' # recursively
(from zsh-lovers)
Edit: tried it now, and had to remove this silly block to make it let me use alternate delimiters:
if [ "${sedscript:0:2}" != "s/" ]; then
echo "Invalid sed script: $sedscript" > /dev/stderr
exit 1
fi
