Question: I want to grep for today's date from zip file. How can do this?

I have a zip file called sen2616.z
I want to get all the data for today's date 09.02.2014

Answer: 
Please use `zipgrep`.

`zgrep` is for gz files, not for zip files.
You can use `zgrep` to get what you want, with:

```
zgrep '09.02.2014' myfile.zip

```

See `man zgrep` for more info.
