rm all except zip files
Eric Gorely
directory except those that end with zip?
I have tried the following:
rm *.!(zip) #will not get files with no extension or with multiple dots in
them
rm *!(zip) #deletes all files, including zip files
rm *.[!zip] #appears to not get files ending with .z, more than one dot,
and no extensions
rm *[!zip] #same as above, except will get files with no extension
rm *![zip] #rm: *![zip]: No such file or directory
Am I close? Is there even a way? I think I understand the behavior of all of
the above except for the second one. Can someone explain? Thanks for your
time. System info:

rm `find * -type d -prune -o -type f ! -name '*.zip'`
If you don't have any subdirectories you can leave out the '-type d -prune
-o' part of the command.

Since you want to do this in CURRENT directory, you can simply use grep,
something like:
rm `ls | grep -v '.zip'`
(or rm `ls | grep -v '.zip$'`)

Yes.
rm !(*.zip)
or if you want to include dotfiles,
rm !(*.zip) .!(*.zip)

I have not tested the above, but I believe that this will not work
if there is no period or if there is a zero, one, two, or a 4+
character extension.
These filenames wouldn't get found:
myfile
myfile.
myfile.z
myfile.zi
myfile.zip1
myfile.more2
.
.
.
etc.
Others have posted good solutions using find.

It will also leave things like *.zig, *.zap, and *.pip.

for each in `ls -1 | grep -v "zip file extension eg .Z"`
do echo $each
done

if the above script lists all the file but your zipped files, replace the echo
with \rm -f.

Yes, you need to give ls the '-d' option to make it act on directories the same
as it does on files.

I got into this late and didn't see the original posting, but I would
like to respond to the above code specifically, without reference to the
original stuff other than to say, I assume we want to keep *zip files
and delete ALL other regular files, from the current directory down. We
will not remove any directories, even if they are empty.
First, simplify: rm has an option, -i that makes it interactive. It
will ask, for each file it is given, whether you want to remove it. An
answer beginning with y is required, anything else skips.
Second, understand find: -name '*' will limit to all names not
beginning with a dot. But we could also limit the find to reporting
about regular files only with '-type f', since we want to skip
directories.
There are possibly a lot of files to find doing this, so 'xargs' is
added to the needed tools:
find . -name '*' -type f -print | grep '\.zip$' | xargs rm -i
Coupla other notes: directory names dot and dot_slash are the same so
go with the simpler; the grep pattern without the dollar sign would save
files like 'the.zipper'.
Cheers,

Even better, because the '-name' parameter takes file patterns we can
drop the grep entirely:
find . -name '*.zip' -type f -print | xargs rm -i
Or interactively delete everything except "*.zip" files:
find . \! -name '*.zip' -type f -print | xargs rm -i
Because this includes ".*" files now, to avoid these we could add:
find . -name '*' \! -name '*.zip' -type f -print | xargs rm -i
or
find . \! -name '.*' \! -name '*.zip' -type f -print | xargs rm -i
(The first works, because "*" by default skips ".*" files, but
for the sake of clarity I'd prefer the second explicit version.)
Please note, that find's '-name' parameter takes file patterns
in contrast to grep's regular expressions!
Regards,
Martin

Has anyone bothered to try one of these suggestions that end with
"... | xargs rm -i"? They don't work! When rm prompts for confirmation
it reads the response from stdin - which is the pipe from "find". If
xargs has already read everything from the pipe, rm will get end-of-file.
If not, rm will read part of the list of filenames as if it was a y/n
response.

Well, it does on some systems, but only if they have a broken version
of find. The POSIX.2 standard says that -name "*" matches files
beginning with dot. This is also the historical behaviour, but
unfortunately some vendors misinterpreted the POSIX.2 spec.

would this not be easyer?
rm -i `find .|grep -v .zip`

Pff, I should have thought of that - and you're right: in this case I
didn't test the commands myself, but only did cut & paste, as my focus
only was on showing some of the possibilities of "find" ...
Sorry for the confusion I might have caused!
Kind regards,

Missed the start of this thread; but there is an easier way to delete
all but a certain name of file:
$ ksh
$ rm -i !(*.zip)
