.zip files

I have been doing some log managment on a site i manage. While doing so i have come across .zip files but when i type zip as root this command is not recognised and there seems to be no man page for zip either. I am used to using gzip so when i found these i was wondering what command might have created them?
I want to conserve space on the filesystem these logs reside and want to compare the compresion ratios of the program that created these .zip files and gzip which i am familiar with already. Any ideas or thoughts would be apprecieated.

Re: .zip files

Zip software doesn't come with the OS.

You need to install Open-Source zip software.

Re: .zip files

The fact that you have .zip files on the server already suggests that you **may** already have the software installed. However, it may not be in your PATH.

Check /usr/local/bin/ for zip programs, likely just zip and unzip. If there is nothing there you should search through /opt as well.

Re: .zip files

Hi Benjanmin,
If you don't have access to an unzipping utility, you can use the jar command, included in the "bin" directory of the Java, as long as it is reachable from your executable path:
jar xvf

It should run also for zip the file.
Take care that the files cannot be larged than 2GB (if I well remmeber).

Re: .zip files


IN line with what Steven has to say , just to add the following thigs if u need to install the unzip on ur system , mind that the unzip is different for different versions of HP-UX and also that u r running that on IA or PA Platform...

What u need is to download the unzip utility from the following site,

The file for the HP-UX 11.23 on an Itanium Platform is

FTP that to the server in the /tmp folder and do an swinstall for that depot file.
#cd /tmp
#gunzip unzip-5.52-ia64-11.23.depot.gz

#swinstall â  s /tmp/unzip-5.52-ia64-11.23.depot

After the installation do
#whereis unzip
get the path
#cp -p /usr/sbin
#cp -p /usr/bin

then get running unzip <.zip_file_that_u_want_to_unzip>
