unable to unzip to opt directory

Question

I'm trying to install jstock to the /opt directory. I'm getting the below error.

1. jstock is in the ~/Downloads directory.
2. The file name is correct.

Kindly guide.

navjeet@navjeet-Lenovo-G50-80:~/Downloads$ sudo unzip jstock-1.0.7.17 bin.zip -C /opt 
[sudo] password for navjeet:  
Archive: jstock-1.0.7.17-bin.zip  
caution: filename not matched:  -C 
caution:filename not matched:  /opt 
navjeet@navjeet-Lenovo-G50-80:~/Downloads$

Note: bin.zip and -C are separated by space, though it looks otherwise.

Solution

Took me a few minutes to see what you were doing wrong. You are using tar syntax for unzip and they aren't compatible. You want to run this:

sudo unzip -d /opt/ jstock-1.0.7.17-bin.zip 

For tar the syntax is tar xf file.tar -C dir whereas for unzip it's unzip -d dir file.zip

It worked wonders! kudos to you and thanks a lot.. Meanwhile i would like to know more about the differences of tar and unzip.

@Krishtopher can i use tar to unzip (or untar , if that sounds correct) a .zip file ?

Nope I just tested tar doesn't support .zip files, it does support .tar.gz and .tar.bz2 files though.
