Regular expressions is a pretty big topic. It's not super easy like
globing (like the * you've been using in bash) which you can get the
idea from the 544 page book (
<a class="moz-txt-link-freetext" href="http://www.amazon.com/Mastering-Regular-Expressions-Jeffrey-Friedl/dp/0596528124/">http://www.amazon.com/Mastering-Regular-Expressions-Jeffrey-Friedl/dp/0596528124/</a>
) that can be bought on regular expressions. The equivalent book on
globing would be a pamphlet. <br>
<br>
That being said, the basics aren't too hard to learn, but you have
to keep in mind that they are fairly different, and don't always act
like what you would think.<br>
<br>
There are a ton of howtos out there and they take a lot of different
approaches to explaining thing, I would just search google for them
until you find one that speaks to you.<br>

<div text="#000000" bgcolor="#FFFFFF"> You can't rename
files that way. The * on the command line gets turned
into real file names by bash before they are ever given to
the mv command so you are tell the command line to consist
of any files with a : followed by any files with an = or
-.<br>
At best your command will error out, at worst it will
overwrite an existing file.<br>
What you are needing is a program that can take a pattern
and rename files with a different pattern. There are 2
that I've used, mmv and rename. Of the 2, you probably
have rename on your system already since it gets pulled in
with PERL. If not, just install the rename package.<br>
<br>
With rename all you have to do is:<br>
rename 's/:/-/' *<br>
<br>
That will use a regular expression to change all the files
in the current directory that contain a : in their name to
the same name with a - replacing the :.<br>
<br>
Be very very careful with the rename command, it can and
will clobber every file that it touches before you know it
just because you got a single character out of place.<br>
When in doubt add the -n option so that it will tell you
what it's going to do without actually doing it. Then if
everything looks good, run the command again without the
-n to actually make the changes.<span class="HOEnZb"><font

<br>
It is not possible to have a ':' character in
a filename on a FAT-based filesystem. This is
because that character was used to denote
which disk drive a file was on back in the DOS
days... "C:\junk\stuff.txt" and so forth.<br>
<br>
I am not sure what these hidden files contain,
or whether they're actually important. You
can pass the "--exclude *\:*" option to rsync
to tell it to not try to transfer files that
contain ':' characters, which may help.<span><font
