Hi to all;

Most of the commands are not found in my OS .
what's the permanent solution ?

IS there any package to get all basic commands ?

PHP Code:



[root@localhost ~]# fstab
-bash: fstab: command not found
[root@localhost ~]# whatis fstab
fstab                (5)  - static information about the filesystems
fstab-sync           (8)  - Update the /etc/fstab file in response to HAL event

fstab is not a command but a file. Usually located in /etc

Which OS is it about ?

? May be this command will tell : $ cat /etc/redhat-release

Hi knudfl;

Thanks to both;
I know this is very old. I am looking to install OEK only.
So i didn't change my OS. Most of the commands are really not found

PHP Code:



[root@localhost oracle]# cat /etc/redhat-release 
Enterprise Linux Enterprise Linux AS release 4 (October Update 4)

OK, Redhat EL.

Commands :
As unprivileged user, you have access to the "2500" commands in /usr/bin/.
And 100 in /bin/.

As root, when you do 'su -' ( su <space> <hyphen> ),
you can use the commands in /sbin/ and /usr/sbin/ . ( About 640 commands.)
With 'su' only : No access, i.e. /sbin/ and /usr/sbin/ are not in your PATH.

When you press TAB twice in your prompt, bash tells you something like
"Display all 4567 possibilities? (y or n)"
Well, what are those 4567 choices exactly? Let's find out...

Code:

compgen -c | sort -u > commands && less commands

1. that is extremely old. I believe the last version of RHEL4 was 4.9

2. RHEL 4 went out of support in February this year http://www.redhat.com/security/updates/errata/

3. as above, all the cmds are there, so long as you use cmds not files.
You'll have to give us some examples of cmds you think are not there

4. post the result of

Code:

echo $PATH

The most common commands (about 100 of them) are supplied by the coreutils package. It is always installed when you install the system.

One way of looking at which are basic commands is that they are universally available. There are some commands that aren't universally available and a few that are different between different Linux distros (eg, networking commands).

Which commands are you actually missing (and not fstab, which isn't a command and isn't missing)?

Apart from what all other senior members have said if you looking for a package for a missing command then you can use

Code:

# yum whatprovides "command name"

this will show you the package name which provides what particular command (again the command may vary as per different distributions, this one is for RHEl and similar distros like CentOS and OEL)
