Accidentally typed "ps -ux]"

Darth Cow · 09-27-2003, 06:12 PM

I accidentally typed "ps -ux]" instead of "ps -ux". Now I'm getting this error message when I attempt to use the command ps:

Code:

[root@www /]# ps -ux


Signal 17 caught by ps (procps version 2.0.6).
Please send bug reports to <procps-bugs@redhat.com>

I'm accessing the server via SSH - I don't have direct access. I not especially familiar with shell commands.

Thanks for your help!

Does this persist over a logout?

I've seen this if /proc isn't mounted. Do mount and past the results here

I'm sorry, but I know what doing "mount" is.

Can you give me a command to do?

Thanks

the command is mount, hence do mount

Boy, that's helpful. Please, in the future, if you have nothing better to do than to make fun of people, don't bother posting.

I think what jvds means is this: the /proc partition is a sort of artificial "disk" that contains information about your hardware, along with what processes are running. Presumably that is where 'ps' gets its information. I suppose you could just look to see if it's already mounted:

ls /proc

If you see a list of a bunch of files, then it's mounted. (By the way, "mounting" is just a way of making a disk available for use. Type 'man mount' for information about how to use it.) If /proc is not mounted, you may need to modify your /etc/fstab file to add a line something like this:

none /proc proc defaults 0 0

Another thing to try, if you haven't already, is just plain 'ps' without the '-ux'. Maybe that option is causing some kind of problems. That is about all I know. Good luck!

Code:

[root@www /]# mount
/dev/sda6 on / type ext2 (rw,grpquota,usrquota)
none on /proc type proc (rw)
/dev/sda1 on /boot type ext2 (rw)
none on /dev/pts type devpts (rw,gid=5,mode=620)

"ls /proc" gets me a long list of files.

Just "ps" on its own gets the same results as with any argument.

Looks like not being mounted isn't the issue.

whoa r u crazy waccaplet. that was a sincere reply. mount tells u everything that is mounted. all u have to do is type mount. i don't c how i was being unhelpful. he asked wut do mount was and i told him do mount means type mount and hit enter. how else would i answer the question.

if proc is mounted it'll tell u so....... don't kno wut your problem is.

anyway, did u do ps ax without the switch, ps doesn't do the '-' c if that works

eltongeoff · 10-05-2003, 12:17 AM

whoa just noticed it says none on /proc. is it suppose to say that? mine says proc on proc.......

My apologies. I guess I misinterpreted your reply.
