Added 'exit 0' To The Bottom Of .bashrc, Now What?

Hello all,
I am working on setting up a script to set certain things and install them on new installs of linux, however I am running into an issue with appending code onto the end of my .bashrc.

I am trying to append Code:

PS1='\033[1;32m[\A \u@\h \W]\033[0m$ '

into .bashrc and I have tried the following methods without success
Code:

echo PS1='\[\e[1;31m\][\A \u@\h \W]\$\[\e[0m\] ' >> /root/.bashrc
echo 'PS1='\[\e[1;31m\][\A \u@\h \W]\$\[\e[0m\] '' >> /root/.bashrc
echo 'PS1=\'\[\e[1;31m\][\A \u@\h \W]\$\[\e[0m\] \'' >> /root/.bashrc
echo "PS1='\[\e[1;31m\][\A \u@\h \W]\$\[\e[0m\] '" >> /root/.bashrc

as well as several others with not avail. the issue is that echo is interpreting the single quotes that I would like printed. I have tried escaping them with not luck. any ideas?

Hi all,

When i try to transfer some doc from one server to another, i met this problem.

[root@esjirp62 ~]# scp .bashrc esjirp62new:~/p62
root@esjirp62new's password:
bash: scp: command not found
lost connection
[root@esjirp62 ~]# which scp
/usr/bin/scp

Just in a few minutes ago, i was using scp and now it is not working any more.

Why is this happening?

Changing umask value for files and directories take effect after reload:
/etc/profile
/etc/bashrc
default permission for all users:
-rw-r--r--
above permission is edited to:
-rw-rw-r--
If a specific user in group having only read permission to a file/directory is created before reload,and Linux server reloads, that user gets rw permission to that file/directory. what is the alternative of securing:
/etc/profile
/etc/bashrc
apart from giving the two files access to root user only, and locking out all other users?

I made the mistake of adding an xterm invocation to my ".bashrc" file. My intent was to simply execute an xterm upon initial login to the KDE environment on Debian Wheezy (though the distro probably would have made no difference). What happened is that with each invocation of "xterm", the new xterm would again invoke an "xterm" via the ".bashrc" file. Duh, infinite recursion of xterms upon login. Is there a simple way to invoke an xterm at login that doesn't itself lookup the ".bashrc" file? By the time someone answers this, I will probably find and answer somewhere in the bash/xterm man pages, but thought I'd throw it out there. Really felt stupid after having realized my mistake. Had to login to recovery command line mode and replace the ".bashrc" file with "/etc/skel/.bashrc". Cheerio

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

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 2274 Apr 12 21:40 shadow-
root@slackwa /etc# ls -la | grep passwd
-rw-r--r-- 1 root root 2362 Apr 12 12:58 passwd
-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.

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?

I am in the process of migrating from a Centos 5 to Centos 6 server. I have duo two factor authentication working on my original server via the ForceCommand parameter in my sshd_config file. SSH login prompts for password and immediately pushed duo authentication to phone.

On my new server, it appears the .bashrc file is executed before ForceCommand, as I migrated my .bashrc from original server to new server. This was not the case previously.

How do I force the ForceCommand to run before any profile dependent .bashrc's?

Thank you.

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

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?
