[SOLVED] Some linux commands are not supported

markush · 11-18-2012, 03:36 AM

The output of the which tells us that the tree command is not installed. The output of

Code:

echo $PATH

tells us, that the pathes are already set correctly. tree will be installed into /usr/bin/ and this directory is in the path.
Therefore no need to change anything at the PATH variables.

yum install tree worked fine for me on Cent O/S.
I don't know your settings for yum,
and usually configuration files will be stored in /etc/yum.repos.d directory.

Code:

yum install tree-1.6.0.tgz

The above does not work, you have to use only yum install tree. Since tree-1.6.0.tgz is a tar.gzip file you have uncompress it first.
Anyway you already have the tree-1.6.0.tgz file or you can also download it from here.
I just tried on cent O/S by manually installing it and it worked nicely.
So just follow the below steps.

Code:

tar -xzvf tree-1.6.0.tgz
cd tree-1.6.0/
make
make install

Thats it!

Code:

tree

if you find any error, find the tree path using

Code:

whereis tree
or
which tree

You may find it in /usr/bin directory now use

Code:

/usr/bin/tree
/usr/bin/tree -a /tmp

yum install tree

or

yum install tree.i386

If still not works download tree rpm from below link

wget http://mirror.centos.org/centos/5/os...0-4.x86_64.rpm

rpm -ivh tree-1.5.0-4.x86_64.rpm --nodeps

Thanks

My Questions

1.What's was the exact problem to install this ?
when i googled , i was trying to execute some commands.
2.what is the specific reason some commands are not working?
for ex :

PHP Code:



[root@localhost ~]# cat   /etc/*-version 
cat: /etc/*-version: No such file or directory

3. How can i check my OS is good or not ?

4. IF u don't mind , can you provide good link to download OEL?
It's for my own practice ... atleast good version to support.

Thanks !!

,

@thiyagusham:
The 'yum' command only work if you OS is not end of lifed. Your version is TOO OLD, full of SECURITY VULNERABILITIES and is NOT RECOMMENDED. Linux is free, just install something newer. According to the informations you posted, your OS has received no updated in 6 years. Installing 'tree' on a modern system is simply 'yum install tree' and nothing else. Installing tree from source DAMAGE YOUR SYSTEM by populating /usr with untracked files.

As for the other questions, I already answered them in my previous post. Your OS is _NOT_ good, it is outdated not only by the time since its inception, but by the fact that security updates don't seem to have been applied at all since it was installed. This is not only dangerous for the integrity of the network this system reside in, but is also a very, very bad way of learning Linux because you _have_ to do thing wrong so it can work.

@ Elv13

Any good link to Download OEL ?

Elv13 · 11-18-2012, 03:28 PM

Oracle Linux is not free. It cost money and if you don't plan to pay this money, use CentOS. CentOS is 100% compatible with OEL and RHEL. They are all built in the same source code. While OEL have some extra features like ZFS and DTrace from Solaris and no-reboot kernel updates, that's about it. CentOS is free and provide free updates. It can be downloaded from their website and will be supported for the same period as OEL and RHEL. Of course, all you get is forum support instead of phone one, but you can buy real support from many companies, including Oracle (if they still offer that, I haven't checked in a while).

As for the images, I think there is a 30 day demo somewhere, but you need to pay for the real deal anyway. So if you want to download a OEL compatible image, get CentOS. Do not, for no reasons what so ever install OEL if you don't plan to pay for it for the lifetime of the OS.

EDIT:
Look:
http://lwn.net/Articles/525230/#Comments
Both OEL, RHEL, CentOS and SL all have the same updates the same day, this is because they are all based on RHEL source code. As soon as one get something, so the others. In fact, CentOS had that kernel update OEL had that day more than 30 hours earlier.

It is good that your problem has solved, but I would like to add:

Code:

root@localhost TREE]# unzip tree-1.6.0.tgz

It's a tar and zipped file. You should have tried opening it using:

Code:

root@localhost TREE]# tar -zxvf tree-1.6.0.tgz

Inside the extract you will find INSTALL and makefile, so you would have to run it to install tree.

chrism01 · 11-19-2012, 12:41 AM

As per Elv13, 'Enterprise Linux Enterprise Linux AS release 4 (October Update 4)' is dead and gone. RH (& therefore Centos, SL, OEL) only support versions 5 & 6.
If you want paid support, use RHEL or OEL. If you want free/do your own support, go Centos or SL.
