Find and Remove Broken Symbolic Links

 find -L ${directory} -type l 
 # remove the broken links
 find -L ${directory} -type l -print0 | xargs -0 rm 

Bulk rename files

For example to change files with extension mkd to rst:

find . -name ".mkd" | sed "s/(.).mkd/mv \1.mkd \1.rst/g" | sh

s3cmd

a: 2010-06-17 t: s3cmd css

# does not seem to auto-detect file type w/o prompting
s3cmd put --guess-mime-type --acl-public *.css s3://your-bucket/your-dir/

Mercurial

Stash working copy changes

1. Use shelve extension

2. Use Mercurial Queues (MQ)

# -f needed as we have local changes
hg qnew -f patch
hg qpop

# later
hg import --no-commit .hg/patches/patch
hg qdelete patch

3. Or without MQ:

hg diff > patch
hg update -C .

then import the patch later ...
