Unix tar file with colons in archived file names

[gmoney3138]

All--

I'm trying to get a clear answer on this one. I have a gzipped tar file
from a customer that was originated on Unix. Inside the tar.gz are a series
of files that look something like this:

systemlog_071607_09:25.log
systemlog_071607_10:07.log

etc...

Basically, as per their log file naming method, they used a colon to
separate hours from minutes--terrible, I know, but it's what I have to work
with.

When the cygwin tar recognizes this, due to Windows restrictions, the output
file is not properly extracted. I Googled around and found options for
--force-file and http://cygwin.com/ml/cygwin/2001-01/msg01536.html this
link , but I still can't get this to work properly.

I am able to get the files extracted if I use WinRAR (it converts : to _ on
extract), but I'd prefer to do this from the shell since I can automate this
more readily. Any ideas how I can do this?

~~Thanks much~~

If you only need to access the results with Cygwin tools, you can use
managed mounts. See the email archives for more discussion/details.

just use "--transform='s/:/_/g'", you can turn the colons into whatever
you want.

Use a managed mount or "--transform s,:,_,g".

I'm not sure what this --force-file you mention is but it's not a valid
tar option. --force-local might have been what you were looking for,
however the purpose of that is for overriding the meaning of colon when
specifying the name of the input file to read, not for dealing with
filenames inside a tarball that contain a colon, so it's irrelevant to
this case.

Thanks to all, that just might be what I'm looking for.

Also, I made a typo in my original message. My mistake :). I meant to type
"force-local" instead of "force-file". According to the tar help pages:

--force-local archive file is local even if it has a colon

I couldn't get this to work, though.

That only means the tar-file-name
so if the archive is named hi:ho.tar you have to use it ( for platforms
where : is allowed in a filename).

Have U tried untarring it through a pipe? U could get a listing (tar
-ztvf ...) and store it in an array, then loop on the array and pipe
each file through a pipe and a filter (tar -zOxvf arch.tar.gz
[ArrayElement] > [modifiedArrayElement]). I don't recall bash array
handling off-hand (I prefer gawk), but U should be able to get it
working without much trouble. As U note, the names are clunky, but
it's better than nothing.
