Space Disk "used" In Df Is Nowhere To Be Found With Du

Hello, this is my first post
First i would like to thank you all for answering other people questions because I've been able to learn from the forum a lot.

I need your help with something.
I have standard output from 'ls -laR /etc' command which looks like this:
Code:

/etc/X11/xorg.conf.d:
total 4
drwxr-xr-x. 2 root root  29 Apr  1 00:46 .
drwxr-xr-x. 5 root root  54 Apr  1 00:43 ..
-rw-r--r--. 1 root root 232 Apr  1 00:46 00-keyboard.conf

/etc/xdg:
total 12
drwxr-xr-x.  4 root root   36 Apr  1 00:43 .
drwxr-xr-x. 87 root root 8192 Apr 12 13:53 ..
drwxr-xr-x.  2 root root    6 Jun 10  2014 autostart
drwxr-xr-x.  2 root root   17 Apr  7 01:25 systemd

by using sed command:
Code:

sed -e '/./!d' -e '/^total/d' -e '/\.$/d' -e 's/:$/\//' list.txt

I have transformed it to the following form:

Code:

/etc/X11/xorg.conf.d/
-rw-r--r--. 1 root root 232 Apr  1 00:46 00-keyboard.conf
/etc/xdg/
drwxr-xr-x.  2 root root    6 Jun 10  2014 autostart
drwxr-xr-x.  2 root root   17 Apr  7 01:25 systemd

and now I would like to achieve absolute paths at the end of each row

Code:

-rw-r--r--.  1 root root  232 Apr  1 00:46 /etc/X11/xorg.conf.d/00-keyboard.conf
drwxr-xr-x.  2 root root    6 Jun 10  2014 /etc/xdg/autostart
drwxr-xr-x.  2 root root   17 Apr  7 01:25 /etc/xdg/systemd

How do I join(merge) filenames with corresponding absolute path to their parent directory?



I know how to extract filenames using awk and get this:
Code:

00-keyboard.conf

autostart
systemd

but I don't know what to do next. Should I use some hitech sed option or go for loop or try with arrays? Help. Heeeelp

I'm trying to recreate a relative symlink, to link "asymlink" to "somedir/actualfile" in /root/test/ but its creating 2 symlinks instead.

Code:

[root]# ln -t /root/test/ -s somedir/actualfile asymlink
[root]# ll /root/test/
total 4
lrwxrwxrwx 1 root root   18 Feb 16 06:15 actualfile -> somedir/actualfile
lrwxrwxrwx 1 root root    8 Feb 16 06:15 asymlink -> asymlink
drwxr-xr-x 2 root root 4096 Feb 16 06:15 somedir

I can do it with
Code:

cd /root/test
ln -s somedir/actualfile asymlink

but I'm trying to avoid the cd, and also avoid using the full path.

Does anyone know why the -t flag isn't working as expected?

I ran into an interesting problem (on reddit) that I figured I could solve, but I have not been able to. Its simple,.. I added 'exit 0' to /root/.bashrc, and now I am trying to log in via ssh.

Everytime I do, it immediately exits when it runs the .bash_profile, which sources .bashrc, (which is immediate upon 'logging in')

I've tried:

Code:

ssh root@192.168.1.50 -t vim
vim scp://192.168.1.50/.bashrc
vim scp://192.168.1.50/root/.bashrc
ssh root@192.168.1.50 bash --norc
ssh root@192.168.1.50 /bin/bash --norc --noprofile
ssh -T root@192.168.1.50 "mv /root/.bashrc /root/.bashRC"
scp .bashrc root@192.168.1.50:/root/
ssh root@192.168.1.50 /bin/bash --norc --noprofile -vvvvvvvvvv
ssh -vvvvvv root@192.168.1.50 /bin/bash --norc --noprofile
ssh -vvvvvv root@192.168.1.50 /bin/mv /root/.bashrc /root/.bashRC
ssh -t -t root@192.168.1.50 << EOF
mv /root/.bashrc /root/.bashRC
EOF
ssh -t -t root@192.168.1.50 --norc << EOF
echo HELLO > /root/.bashrc
EOF
ssh -tv root@192.168.1.50 rm .bashrc

So,.. I am unable to get back into the system (as root, no other users exist) after adding 'exit 0' to .bashrc

Anyone feel like explaining why all of these failed (aside from saying SSH interactive logins run the .bash_profile/.bashrc files) or, offering a suggestion that works? Seems like if you have the root password, you should be allowed to modify the login process... since... you know... you are root.

Hi all,

I am slackware 14.0 user. Recently I face one problem. As a root i can change one of my normal user's (assuming Peter) password. However, when I login as Peter, and try to change the password, the system does not allow me to renew my password.


root@slackwa /etc# ls -la | grep shadow
-rw-r----- 1 root shadow 9 Nov 29 2013 gshadow
-rw------- 1 root root 0 Jun 20 2013 gshadow-
-rw-r----- 1 root shadow 2272 Apr 12 22:44 shadow

-rw------- 1 root root 2306 Jan 8 17:38 passwd-
-rw-r--r-- 1 root root 2305 Aug 11 2014 passwd~


peter@slackwa ~$ which passwd
/usr/bin/passwd
peter@slackwa ~$ ls -la /usr/bin/passwd
-rws--x--x 1 root root 68725 Sep 14 2012 /usr/bin/passwd*

peter@slackwa ~$ passwd
Changing password for peter
Old password:
Incorrect password for peter.
The password for peter is unchanged.

One thing I can assure is the password I input is correct. I have another slackware 14 running on Dell R410, but it does not has this problem.


Please kindly advice. Thank you.

Dear Members,

I have two raspberrys, one running OSMC and another running raspbian. The first one has two 1TB hard drives plugged in through a powered usb hub. I want to access to the osmc hard drives from the one running raspbian. They are both in the same local network, the osmc one has the ip 192.168.1.24 and the raspbian one has 192.168.1.28. Both are static ips.

These are the hard drives::
Code:

osmc@osmc:~$ ls /media/ -la
total 36
drwxr-xr-x  4 root root  4096 Mar 31 18:28 .
drwxr-xr-x 23 root root  4096 Mar 15 13:35 ..
drwx------  1 osmc osmc  8192 Mar 30 21:54 ELEMENTS
-rw-r--r--  1 root root   232 Mar  6 13:34 README
drwx------  1 osmc osmc 16384 Mar 30 15:22 TOURO

ELEMENTS and TOURO, two ntfs hard drives that work just fine.

I tried sharing the first one through nfs with the following config (i copied the parameters from a tutorial):
Code:

osmc@osmc:~$ cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
/media/ELEMENTS/Pelis/ 192.168.1.0/24(rw,subtree_check,insecure,no_root_squash)
/media/TOURO/Series/ 192.168.1.0/24(rw,subtree_check,insecure,no_root_squash)

and from the pi running raspbian I have confirmed that I can see the drives being shared:
Code:

 /media $ showmount -e 192.168.1.24
Export list for 192.168.1.24:
/media/TOURO/Series/   192.168.1.0/24
/media/ELEMENTS/Pelis/ 192.168.1.0/24

Now, when I try to mount them, all works fine, but when I ls the folders nothing cames back. This is my fstab:
Code:

1cat /etc/fstab
proc            /proc           proc    defaults          0       0

/dev/mmcblk0p2  /               ext4    defaults,noatime  0       1
# a swapfile is not a swap partition, so no using swapon|off from here on, use  dphys-swapfile swap[on|off]  for that

192.168.1.24:/media/ELEMENTS/Pelis /media/pelis nfs rsize=8192,wsize=8192,timeo=14,intr
192.168.1.24:/media/TOURO/Series /media/series nfs rsize=8192,wsize=8192,timeo=14,intr

Code:

apoc@raspbian ~ $ ls /media/pelis/
apoc@raspbian ~ $

The superweird thing is that they are mounted, as they show up if I run "df -h"

Code:

 df -h

Both users ("osmc" in the osmc pi and "apoc" in the raspbian one) have the same uid: 1000.

What am i doing wrong?

Hi Guys,
i have this Code:

uid=0(root) gid=0(root)

i would like to have the word "root" only from the first field, and later from the second field

i use the command
Code:

[root@v1-6 ~]# cat test-uid |cut -d"(" -f1
brms2
uid=0

[root@v1-6 ~]# cat test-uid |cut -d")" -f1
brms2
uid=0(root

it cut the word after the -d, how can i make it to cut the word BEFORE the -d

expected should be:
cut -d"(" -f1
root)

then i can proceed to eliminate the ) later on.
hope this is not confusing you guys

Thanks,

Hi All,

Not able to find TREE command in EL6, its working fine in EL5. Need help on this.

Below are the details.



[root@localhost ~]# mkdir -p /college/sports/performer/cricket

[root@localhost ~]# tree /college/
-bash: tree: command not found

[root@localhost ~]# tree college/
-bash: tree: command not found

[root@localhost ~]# which tree
/usr/bin/which: no tree in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin: /usr/bin:/root/bin)

[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

[root@localhost ~]# id
uid=0(root) gid=0(root) groups=0(root),1(bin),2(daemon),3(sys),4(adm),6(disk),10(wheel) context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

Does it make any difference where a simlink is performed? Will a simlink be global when done in root or /root? Will the simlink be recognized by all users when done in root or /root?

Thanks.

when a command is typed(i.e. /path/to/the/program), as a normal user, he should be able to run that command , execute that program as ROOT and log out root after the execution is completed.
Only one user should be able to do it.
Hence, I have created a new user vj and added the following command in visudo:
Code:

vj ALL=(ALL) NOPASSWD: /path/to/the/program

Now user vj will be able to typein the command.

What I need is that the program which is been called must run as if it is run by a root user,and when the program is completely executed, exit the root user.

How do I proceed?
