Facing a Problem with "ls" command.

vasulogin · 11-27-2008, 12:46 AM

Hi..

can some tell me how to come out with "ls" command problem. the Problems is as shown bellow.

[root@vasant ~]# ls -h
ls: invalid option -- h
Try `ls --help' for more information.
[root@vasant ~]# ll -h
ls: invalid option -- h
Try `ls --help' for more information.

here with ls -h option is not working and when I checked with version it was changed to older.

i.e.,

[root@vasant ~]# ls --version
ls - GNU fileutils-3.13
[root@vasant ~]#

When the OS (I'm using CentOS 5 before this i was RHEL 5. due to same problem i went with reinstall option and i change over to CentOS 5) was installed it was working fine. after some days i started with above problem.

So please help me to come out with this problem. or else i need to keep re-installing the OS, which i cant do it as my system is a small server with nfs configured.

Thanks in advance.

Interesting. On my F8 I get

>ls --version
ls (GNU coreutils) 6.9

I wouldn't have expected that large a diff in version nums.

Try

which ls

Also, try re-installing fileutils from the DVD and then immediately check the -h flag and the version.
There's a small possibility someone has put a different (rogue ? ) version on your system.

Also see if you have ls (or anything else for that matter) aliased. Use the "alias" command to find out whether ls is aliased.

FC10 "ls (GNU coreutils) 6.12", ls -h works fine.

As already suggested check if ls is aliased to something else and/or points to an older installed package. Try:

Code:

type ls
which ls
whereis ls

The GNU fileutils package has been dismissed long time ago. Here it is the explanation from the GNU website:

Quote:

Fileutils, Shellutils, and Textutils have been combined into the GNU Coreutils package.
All further development and discussion is now taking place as Coreutils. The last separate
versions were fileutils-4.1.11, textutils-2.1, and sh-utils-2.0.15. The first major release
of coreutils-5.0 was announced on Fri, 4 April 2003.

Run rootkit hunter to check if your system has been hacked. ls -h should work on any system

I had a similar issue.
based on a reply by Matir to a post of a similar issue, I found that I had a file named -2016... whatever.
The issue was the - (hyphen) an ls -Option switch.. Never had issue before, but after renaming -2016..file to, well just minus the hyphen, all was well again.
Weird thing is I've always used hyphens and root didn't have the issue.

On CentOS 7 in a VM, I get this in my ~/Downloads directory.

Code:

$ ls -h
keepassx-0.4.4-1.el6.x86_64.rpm

It also seems to work properly in the Slackware --Current host.

Not every thing is a "rootkit".
Terrible Advice IMO.
check for aliases, and exports?

Code:

bash --norc && ls -h

or

Code:

\ls -h

or

rootkit?
Yeah b/c hackers can be outed by ls ?

Check integrity with

Code:

rpm --verify rpm && echo ok
rpm --verify bash && echo ok
rpm --verify coreutils && echo ok

BW-userx · 12-21-2016, 12:43 PM

did you

Code:

ls --help

to see what is available to you, and how to use them with your ls command?

$ \ls --help

As previously mentioned, the \ before the command overrides any existing aliasing.

$ ls -l $(which ls)
-rwx-r-xr-x 1 root noob 118280 Mar 14 2015 /bin/ls -> /home/noob/hacked_you_bro

Just curious if the that is the ls you were looking for.

You might check the man page for ls, it might have just been different back then (doubt it). Although -h is the old notation, the --help is a fairly new "standard". Otherwise libc6 / binutils might have gotten corrupted. Check the partition for corruption and the device for any ailments (failings).
