How can i zip a file
 

Hai,

I have written a script in perl which writes some data to a file. As the data written in that file is more, and the size of that file is more, I want to zip the file after the data being written to it.

Please help me to do this.

Thanks,
Prakash.

use: zip -r [new.zip] [path]
example. zip -r var.zip var/*

Hi,

Thanks for your reply.

I tried
zip -r new.zip /tmp/new.csv

and also
zip -r /tmp/new.zip /tmp/new.csv

but in both instances its saying that there is a syntax error.

Can you please post me the complete syntax.


Thanks,
Prakash.

Bzip and bzip are more often used to compress files in Linux and Unix.

Hi,
I am not trying to add any thing to an existing zip file. I just want to decrease the size of the file(compress) by converting it to a zip file.

Please help me in doing so.


Thanks,
Prakash.

Why don't you just bzip or gzip it then, as jschiwal suggested? Read the man pages for bzip2 and gzip for more info on how to use those.

Hai,

Thanks for your reply.
I just converted a tar file for that file which decreases its size for almost 10%.

My problem is solved.

Thanks,
Prakash.

Tar has an option (-z) for gzip and (-j) for bzip. If you only have a single file, you can use gzip & bzip2 on there own. For a single file, you can also expand them using zcat (gzip files) and bzcat (bzip2). This would allow you to do things like grep for a pattern inside a compressed file:
example:
zcat /proc/config.gz | grep NLS

Thanks for your reply. I will have a look at it.

in general if you add -z to tar you get a .tar.gz file that is quite quick to compress and has a reasonable compression,

if you use -j you get .tar.bz2 that is slower to compress but is a better compression level

There are literally dozens (if not hundreds) of perl modules to deal with compressed files on any imaginable format. Since your script is written in perl, I think that it would make more sense to use one of these modules.
