Tools
Up to now there are these tools:

reprec: Replace strings in text files. Can work recursive in a directory tree
setops: Set operations (union, intersection, …) for line based files.

reprec
The tool reprec replaces strings in text files:
===> reprec --help
Usage: reprec
[-p|--pattern] p
[-i|--insert] i
[-f|--filename regex]
[-n|--no-regex]
[-v|--verbose]
[-a|--ask]
[--print-lines]
[--dotall]
[--ignorecase]
[--no-std-exclude]
[--files-from file|-]
[--ignore regex]
[--print-std-exclude]

dirs

dirs: Directories or files for replacing. Use is '.' for current dir.

pattern: Regex pattern.

insert: Text which gets inserted

filename: Regex matching the filename. E.g. '.*\.py'

no-regex: Normal string replacement will be used.
This means you can use '.', '*', '[' without quoting

verbose: Print the number of changes for each file

print-lines: Print the old and the new line for each change.
Not available if --dotall is used.

dotall: In regular expressions '.' matches newlines, too.
Not supported with --ask and --print-lines.

ignorecase: ...

no-std-exclude: Don't exclude the directories called '.git' or '.tox'.
By default they get ignored.

ask: Aks before replacing (interactive).

files-from: Read filenames from file or stdin if '-'.
Skip directories.

ignore: Ignore lines that match a regular expression.
This options can be given several times.

print-std-exclude: print the directories which get ignored (use --no-std-exclude to
not ignore them)

Example:
reprec --pattern '(xml)' --insert '\1\1' .
-->This will replace all 'xml' with 'xmlxml'

Or, shorter:
reprec '(xml)' '\1\1'

Example2:
find -mtime -1 -name '*.py' | reprec --files-from=- foo bar

The Perl Compatible Regular Expresssions are explained here:
http://docs.python.org/lib/re-syntax.html

The files are created by moving (os.rename()) FILE_RANDOMINTEGER
to FILE. This way no half written files will be left, if the
process gets killed. If the process gets killed one FILE_RANDOMINTEGER
may be left in the filesystem.

setops
The tool setops provides set operations (union, intersection, …) for line based files:
usage: setops [-h] set1 operator set2

Operators:
union Aliases: | + or
intersection Aliases: & and
difference Aliases: - minus
symmetric_difference Aliases: ^

Examples

#Show all files in directory "a" which are not in directory "b":
setops <(cd a; find ) - <(cd b; find )

# Create some files for testing
echo foo > foo.txt
echo bar > bar.txt
echo foobar > foobar.txt

# All files minus files containing "foo"
user@host$ setops <(ls *.txt) - <(grep -l foo *.txt)

# All files containing "foo" or "bar" minus files which contain "foobar"
setops <(setops <(grep -l bar *.txt) + <(grep -l foo *.txt)) - <(grep -l foobar *.txt)

positional arguments:
set1
operator
set2

optional arguments:
-h, --help show this help message and exit
