Unix genius - remove "." from a bunch of filenames?

I have an amount of files, somewhat inexplicably, but due to extenuating circumstances, receive a ". " (period AND space) appended to the front of the filename.

I would like to write a bash script to remove this, but I don't really know where to start.

I ca开发者_开发问答n retrieve a list of all the affected files by

find dir -name ".*"

But that's about all I know. Can anyone help me out?

find dir -type f -regex ".*/[.] .*" -exec rename ". " "" {} \;

Find everything within dir where the name matches the regular expression ".*/[.] .*" - "Anything, slash, dot, space, anything"

For each found file, execute: rename ". " "" filename which changes ". " to "" in the file called filename

If you have the Perl script version of rename:

find dir -name '. *' -exec rename 's/^. //' {} \;

for fn in \.\ *; do mv -T "$fn" "${fn:2}"; done

The -T is for safety, i.e., treat "${fn:2}" as file instead of directory.

(Tested in bash)
