Avoid unwanted path in Zip file

I'm making a shell script to package some files. I'm zipping a directory like this:

zip -r /Users/me/development/something/out.zip /Users/me/development/something/folder/

The problem is that the resultant out.zip archive has the entire file path in it. That is, when unzipped, it will have the whole "/Users/me/development/anotherthing/" path in it. Is it possible to avoid these deep paths when putting a directory into an archive?

When I run zip from inside the target directory, I don't have this problem.

zip -r out.zip ./folder/

In this case, I don't get all the junk. However, the script in question will be called from wherever.

FWIW, I'm using bash on Mac OS X 10.6.

Solution 1:

Your script should use cd or pushd and popd to move into the directory that will be the root of the archive before issuing the zip command. How you do this exactly will depend on how the script knows what to zip up. But, if you want /Users/me/development/something/folder zipped with internal paths of just ./folder, you'd need to do this:

pushd /Users/me/development/something
zip -r /path/to/out.zip ./folder/
popd

That will result in your out.zip containing the relative paths you want.

If you need assistance with scripting that, you'll need to show us your script.

Yes. Use the -j option with zip. -j is "junk the path". According to the man page on zip:

Store just the name of a saved file (junk the path), and do not store directory names. By default, zip will store the full path (relative to the current directory).

Using -j means the following command:

zip -j myarchive.zip file1.txt dir1/file2.txt dir2/dir3/file3.txt ../file4.txt

Will create an archive that looks like:

myarchive.zip
    |
    +-- file1.txt
    +-- file2.txt
    +-- file3.txt
    +-- file4.txt

Solution 3:

There is pushd and popd and $OLDPWD. Assuming the $PWD is /Users/me/development do:

pushd something/folder
zip -r $OLDPWD/something/out.zip *
popd

Now the $PWD is back to /Users/me/development
