Bash command not found

Legolas327 · 06-26-2007, 06:17 PM

Why do I get the "bash ????? command not found" for all of my lsmod, lsusb, lspci .etc commands?

distro: FC5 kernel-2.6.20-1.2312.fc5

Here is an example:

Code:

[mythtv@245 sbin]$ ls -l lsmod
-rwxr-xr-x 1 root root 6356 May 10  2006 lsmod
[mythtv@245 sbin]$ su
Password:
[root@245 sbin]# lsmod
bash: lsmod: command not found
[root@245 sbin]#

I know this is stupid like pathing or something but I am running these from within /sbin so not sure what I am doing wrong.

try /sbin/lsmod

SciYro is right - use the full path to the command, or if you are in /sbin directory, try ./lsmod. By default, the current directory is not included in the path. There's a discussion on the merits of this here at http://www.linuxquestions.org/questi...d.php?t=562410

/sbin is not in users path, su gives root rights without switching the environment. Try su -.

Use "su -" to use roots PATH variable.

Also make sure that the package with lsmod is installed.

You can also include the path with sudo:
sudo /sbin/lsmod

It's true that using su - will provide access to the root account which does have /sbin in its path. However, commands like the ones posted by the OP (lsmod, lsusb, lspci) don't require root privileges to run.

Quite true--there are several choices:
su - to get root's PATH
add the directories to the user's PATH
use the full pathname

Why does "su -" but not just "su" without the "-" ?

I added /sbin/ to my Path so now I should not face this again.

[mythtv@245 ~]$ export PATH=$PATH:/sbin/

Thank you very much

From the man page for su: The "-" character tells su to provide an environment similar to what the user would expect had the user logged in as root directly.

It gives you choices about how your environment is structured for different system tasks.
