Command to zip a directory using a specific directory as the root

command, command-line, linux, zip

Solution

I don't think zip has a flag to do that. I think the only way is something like:

cd /var/www/oraviewer/rgn_download/download/ && \
   zip -r fcst_20100318_0319.zip fcst_20100318_0319

(The backslash is just for clarity, you can remove it and put everything on one line.)

Since PHP is executing the command in a subshell, it won't change your current directory.

Problem

I'm writing a PHP script that downloads a series of generated files (using `wget`) into a directory, and then zips then up, using the `zip` command. The downloads work perfectly, and the zipping mostly works. I run the command: ``` zip -r /var/www/oraviewer/rgn_download/download/fcst_20100318_0319.zip /var/www/oraviewer/rgn_download/download/fcst_20100318_0319 ``` which yields a zip file with all the downloaded files, but it contains the full `/var/www/oraviewer/rgn_download/download/` directories, before reaching the `fcst_20100318_0319/` directory. I'm probably just missing a flag, or something small, from the zip command, but how do I get it to use `fcst_20100318_0319/` as the root directory?
