can not unrar the files - linux

The following is my machine, its VM
Linux localhost.localdomain 2.6.32-220.el6.x86_64 #1 SMP Tue Dec 6 19:48:22 GMT 2011 x86_64 x86_64 x86_64 GNU/Linux
I downloaded and untar the rar packages like following
drwxr-xr-x 2 cloudera cloudera 4096 Dec 12 2009 rar
-rw-rw-r-- 1 cloudera cloudera 831871 Dec 12 2009 rarlinux-3.9.1.tar.gz
went to RAR folder
[cloudera#localhost rar]$ ls -ltr rar unrar
-rwxr-xr-x 1 cloudera cloudera 205328 Dec 12 2009 unrar
-rwxr-xr-x 1 cloudera cloudera 364580 Dec 12 2009
[cloudera#localhost rar]$ ./unrar
bash: ./unrar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
but If I try with sudo , error suppress but no output
[cloudera#localhost rar]$ sudo ./unrar e /home/cloudera/Downloads/xyz.rar
[cloudera#localhost rar]$ <<<Nothing happens>>>>
[cloudera#localhost rar]$ ls /home/cloudera/Downloads/
xyz.rar ----<<< same one file remains the unrar does not work>>>>

Ewww! Cloudera - My Pet hate! ;-)
Looks like you are missing a dependancy I did this with a Fedora box and got your error and resolved it with:
yum install glibc.i686
May need to adapt depending on your Linux Distro
HTH's Thanks //P

Only some binaries are visible in pycharm python venv

I check for the existence of installed tools via shutil.which()
Both tools are installed via apt get install ffmpeg mediainfo and their binaries are located in /usr/bin with the same file flags and ownership in the host system:
lala#lala:/usr/bin$ ls -la ff*
-rwxr-xr-x 1 root root 301544 May 19 2022 ffmpeg
-rwxr-xr-x 1 root root 22920 Feb 14 2022 ffmpegthumbnailer
-rwxr-xr-x 1 root root 149984 May 19 2022 ffplay
-rwxr-xr-x 1 root root 178832 May 19 2022 ffprobe
lala#lala:/usr/bin$ ls -la media*
-rwxr-xr-x 1 root root 47352 Apr 3 2022 mediainfo
-rwxr-xr-x 1 root root 374000 Apr 3 2022 mediainfo-gui
BUT within the virtual environment only one of them is available. The other one simply doe not exist
sh-5.1$ /usr/bin/ffmpeg
ffmpeg version 5.0.2 Copyright (c) 2000-2022 the FFmpeg developers
[... more ...]
sh-5.1$ /usr/bin/mediainfo
sh: /usr/bin/mediainfo: No such file or directory
So what could be the reason, why one binary is available and the other one is not.
Edit: this happens only in the termial / execution environment within pycharm
It turns out that Pycharm installed by flatpak has its own "environment" where one of the binaries was installed - the other one was not.

What's the difference between libjpeg.so.8 and libjpeg.so.62

There are always jpeg decoder libraries pre-installed on Linux like:
/usr/lib/x86_64-linux-gnu/libjpeg.so
/usr/lib/x86_64-linux-gnu/libjpeg.so.62
/usr/lib/x86_64-linux-gnu/libjpeg.so.62.0.0
/usr/lib/x86_64-linux-gnu/libjpeg.so.8
/usr/lib/x86_64-linux-gnu/libjpeg.so.8.0.2
What is the difference between the so library? Does libjpeg.so.62 build from libjpeg-turbo?
Firstly, if you run:
ls -l /usr/lib/x86_64-linux-gnu/*jpeg*
you will see that most of the files are just symlinks to the one with the full version, so programs can link against the latest one by specifying an unversioned library in the knowledge that it will point to the latest version:
lrwxrwxrwx 1 root root 17 Oct 20 2016 libjpeg.so -> libjpeg.so.62.2.0
lrwxrwxrwx 1 root root 17 Oct 20 2016 libjpeg.so.62 -> libjpeg.so.62.2.0
-rw-r--r-- 1 root root 436224 Oct 20 2016 libjpeg.so.62.2.0
Secondly, unfortunately I don't have the same files as you else I would help further, but in general, you can find which package a given file comes from like this:
dpkg -S someFile
So, on my system, I can see that libjpeg.a for example, comes from package libjpeg62-turbo-dev
dpkg -S libjpeg.a
libjpeg62-turbo-dev:amd64: /usr/lib/x86_64-linux-gnu/libjpeg.a

Install oracle imp / exp in Ubuntu

I have this Ubuntu version:
Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS
Release: 14.04
Codename: trusty
I just download oracle-instantclient12.2-basiclite-12.2.0.1.0-1.x86_64.rpm and install the tools using
alien -i oracle-instantclient12.2-basiclite-12.2.0.1.0-1.x86_64.rpm
But I can't find the exp anywhere, just these 2 files
root#localhost:/usr/lib/oracle/12.2/client64/bin# ls -la
total 108
drwxr-xr-x 2 root root 4096 Nov 8 14:47 .
drwxr-xr-x 4 root root 4096 Nov 8 14:47 ..
-rwxr-xr-x 1 root root 43797 Mar 16 2017 adrci
-rwxr-xr-x 1 root root 56984 Mar 16 2017 genezi
The utilities are not part of the basic (or basiclite) package. The instant client download page lists the packages and what they contain. You need to get the tools package, oracle-instantclient12.2-tools-12.2.0.1.0-1.x86_64.rpm, in addition to the basic package, to be able to use exp and imp (and their datapump equivalents; and SQL*Loader).
You may find the SQL*Plus package useful as well.

How to install upgrade to new version of awstats Linux / UNIX *.tar.gz tarball files

I currently have awstats 7.0 which is from 2010. I would like to update to current stable relase, which is awstats 7.3
I tried
tar zxf awstats-7.3.tar.gz
cd awstats-7.3
ls -al
drwxr-xr-x 5 puter puter 4096 Jan 29 2014 .

make install

???
please, advise. Thank you.
I also followed this link
http://www.awstats.org/docs/awstats_upgrade.html
however, I dont really know where to distribute the files on the system.
lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 7.5 (wheezy)
Release: 7.5
Codename: wheezy
If the first command you try to run (./configure) fails (No such file or directory), then probably you should stop right there. The rest of the commands won't work any better.
Did you read the README.TXT file?
Awstats doesn't seem to be a program that needs to be compiled, and it doesn't have a configure script (obviously since you showed the list of files and there isn't one there). I googled for "awstats install" and found this page where it says:
After downloading and extracting the AWStats package, you should run the awstats_configure.pl script to do several setup actions. You will find it in the AWStats tools directory
and you clearly have a tools directory, so I would start with that.

dpkg --list not showing installed kernel version

I am running ubuntu 14.04 with kernel 3.13
I was following eudyptula challenge which asked me to download kernel source from linus's git and build,install, which I did and now I have two kernels, 3.13 and 3.15.
I wanted to verify the installation and read on some website that dpkg --list | grep linux-image would give me list of all installed kernels but I get only 3.13.
I currently booted 3.15
terminal outputs below:
ashish#ashish-PC:~$ uname -r
3.15.0-07913-g64b2d1f
ashish#ashish-PC:~$ dpkg --list | grep linux-image
ii linux-image-3.13.0-24-generic 3.13.0-24.46 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP
ii linux-image-extra-3.13.0-24-generic 3.13.0-24.46 amd64 Linux kernel extra modules for version 3.13.0 on 64 bit x86 SMP
ii linux-image-generic 3.13.0.24.28 amd64 Generic Linux kernel image
If you installed from source not creating a .deb package dpkg --list won't show you because it didn't install it and knows nothing about it.
check your /boot directory:
$ ll /boot/
