Installing and using p7zip?

spider99 · 05-17-2010, 10:44 AM

I'm new to Linux and have a CentOS system, i downloaded p7zip (a file that extracts rar, 7z etc) but don't know how to install it or use it, would someone help me out here?

Hi,

Firstly I assume you've downloaded the binary install from SourceForge?

In that case...this is what you do:

1. Download the tarball to your machine.

2. Move the tarball to the location of your choice:

Code:

# mv /apps/p7zip_9.04_x86_linux_bin.tar.bz2 /your/location/

3. Unpack the tarball:

Code:

# tar -xjf /apps/p7zip_9.04_x86_linux_bin.tar.bz2

4. Run the executable:

Code:

# ./7za

7-Zip (A) 9.04 beta  Copyright (c) 1999-2009 Igor Pavlov  2009-05-30
p7zip Version 9.04 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,2 CPUs)

Hope this helps,

Cheers,
Yas

Ty but when i try

Quote:

# ./7za file.7z

Quote:

No such file or directory

And i'm using the terminal in the directory of the file i want to extract

First cd to the directory created by the untar command.
Why don't you use rpm?

I already installed the p7zip-4.58-1.el5.rf.i386.rpm for centos but still when i excute the command it still says the same thing

repo · 05-17-2010, 11:46 AM

What is the output from

Code:

whereis 7za

If you installed the rpm the commands are

Code:

7z   7za  7zr

spider99 · 05-17-2010, 11:56 AM

The rpm is already installed, the command i'm using is

Quote:

# ./7za /Desktop/file.7z

Quote:

# ./7za file.7z

but it returns with the error [No such file or directory]. The file i wanna extract is located at ./Desktop/file.7z.

repo · 05-17-2010, 11:59 AM

If the rpm is installed, no need to install the tar file.
try

Code:

7za /Desktop/file.7z

Code:

./7za

means the file you want to execute is in the current directory.

7za /Desktop/file.7z

It errors- Incorrect command line.

repo · 05-17-2010, 12:29 PM

what is the output from

Code:

whereis 7za

Did you read the manfiles?

Code:

man 7za
man 7z
man 7zr

spider99 · 05-17-2010, 12:41 PM

The output from 7za is at /usr/bin/7za however the output from 7z and 7zr is blank.

I'm unsure of the way the command should be, would anyone provide an example on how to extract a file using p7zip?

repo · 05-17-2010, 01:02 PM

From the manpage and 7za -h

Code:

  a: Add files to archive
  b: Benchmark
  d: Delete files from archive
  e: Extract files from archive (without using directory names)
  l: List contents of archive
  t: Test integrity of archive
  u: Update files to archive
  x: eXtract files with full paths

spider99 · 05-17-2010, 01:05 PM

I read the manual but it says incorrect command line or no such archive thus me needing an example :P

repo · 05-17-2010, 01:13 PM

If you read the manpage:

Code:

7za e path_to_whatever_file_you_want_to_extract.7z
