    Simple question for someone who knows anything about zip

    I'm writing a script that unzips an archive, edits it, and zips it back up.

    That being said, I've got it all figured out except for the zipping it back up.

    Code:
    unzip file.zip -d /tmp/foobar
    ##regexes###

    Now when i get to zipping the files back up, I don't want to include the /tmp/foobar directory I created. I want it to have the same tree as before.

    I've gotten two commands to come close, but not what I want.

    Code:
    zip -r /tmp/file.zip /tmp/foobar/*
    - this zips up the folders and files within /tmp/foobar/ however, it includes the /tmp/foobar tree.
    Code:
    zip -rj /tmp/file/zip /tmp/foobar/*
    - this gets rid of the directories, however, it gets rid of ALL the directories, and doesn't preserve any within /tmp/foobar.

    Now, by default zip will ignore /tmp/foobar if you're in that directory and running zip from there. But since this is a script I don't want to be limited to where I can run the script, or lower my standards to including changedirectory lines in my script. It seems to me like I should be able to 1-liner it, and it's frustrating me.

    Anyone use zip enough to be able to help me?

    Bumping after 30 minutes is a bit excessive there ...

    Your command "zip -r /tmp/file.zip /tmp/foobar/*"
    tells to zip everything in the /tmp/foobar/ directory into /tmp/file.zip.

    You want to *exclude* that folder, so you must specify it with the -x (see man pages).

    It would thus look like :
    zip -r /tmp/file.zip /what-you/want-to-zip/* -x /tmp/foobar/*

    If there are many directories you wish to exclude, you could create a file named "exclude.lst", include all the directories to be excluded, and write :
    zip -r /tmp/file.zip /what-you/want-to-zip/* -x@exclude.lst

    I did look at the man page, several times. However after trying every combination using -x I looked at the man page again looking for examples, and -x only excludes files, not directories.

    Any other ideas?

    Code:
    zip -r /tmp/file.zip /tmp/foobar/*
    - this zips up the folders and files within /tmp/foobar/ however, it includes the /tmp/foobar tree.

    Have you tried running the command from the /tmp/foobar directory?

    For example:
    Code:
    cd /tmp/foobar
    zip -r /tmp/file.zip *
    I would think that should fix your problem.

    By including the path in your zip command it will include the path in the zip file.

    Sry, didn't see first post. My answer was stupid. How do you delete a post?

    Linux isn't necessarily the most efficient home Operating System. Quite the contrary.

    this seems like the best solution. set your path as a variable then you can use it when you unzip, and then again to change directory before zipping back up. if its always gonna be in /tmp/ then you dont even need to do that.

    The above posters are correct; you need to change directory first.

    I don't know how changing a directory would "lower standards". You may find the commands pushd and popd useful, as they let you remember where you were before changing directory.
    Always make regular backups of your data (and test them).

    Re: Simple question for someone who knows anything about zip

    I guess cd-ing isn't "lowering my standards", it just seems like I should be able to just say in one command "zip this directory and everything underneath it, and nothing above it". That doesn't seem like it's asking too much does it?

    More than anything it's become personal between me, my coworkers and zip....
