Hi,
I am using centOS which is identical to RH Enterprise linux but when type
lsdev or lsscsi, the system tells me that command not found. Why don't i have these utilities?

Moreover, when i login as normal user and even su (just "su", not "su -"), i cant invoke lspci, lsmod... However, when i use "su -", i can invoke those comamnd. As far as i know, when a user type a command, the system look for the command in the PATH associated with the user profile so the PATH must be the same as long as i am root ("su" or "su -"). The different between su and su - is just the directory i am in, so why can't i invoke lspci and some other command when i am in a non-root directory?

Thanks in advance

Because they are not part of the Red Hat Enterprise Linux release.


When you use 'su' you inherit the users pathing, using 'su -' provides root's pathing. This does not matter which directory you are in. As an experiment use $PATH, look at your user path by typing this. Next use 'su' and try $PATH again exit the do the same after using 'su -', see the diiference.

And you can modify your user pathing to add /sbin and other wanted directories to your user pathing (look at the user's .bash_profile file). Or simply do something like for example;

$ locate lspci
/sbin/lspci
/usr/share/man/man8/lspci.8.gz

$ /sbin/lspci

Thanks for the instruction. You said that lsdev is not part of RH Enterprise, so where i can get these utilities? What package i should install to have lsdev and lsscsi?
Thanks

I'm not 100% sure for either utility, but google should be helpful. You do not need either one, try using as replacements (maybe make alias's for them)

cat /proc/scsi/scsi

lspci -v

Hi, you do have lsscsi in Linux Centos 5.X. You just need to install the package.

yum install lsscsi

and there you are !

try "yum install procinfo"
this provides the lsdev utility.

My employer hobbles yum by hacking out many repository names. So, could you supply the repository info and instructions on how to add it to the repositories list?

A good tool for finding packages is
http://pkgs.org/
This shows lsscsi in CentOS, but procinfo is only in CentOS 5 and Fedora. You can follow their links to a download page, get the rpm, and install locally.
