By mistake I have modified the PATH variable you know what a kind of mess it is.
Code:
echo $PATH
I just need to set the path variable again so I just need the format. Or can anybody come up with how to set the path variable.
I was changing my sudoers file to give permission of using "sudo" command to all root commands, asking for the password. It works, it's fine. The problem I'm having is with the variable PATH to my user, I think.
In terminal:
normal user:
Code:
ataias@ataias-notebook:~/Downloads$ echo $PATH
/usr/local/bin:/bin:/usr/bin
super user:
Code:
root@ataias-notebook:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin
As many commands are in /sbin/, root can use them without writing "/sbin/" but I can't do the same cause it's not in my path.
while root do this:
Code:
shutdown -h now
I should do:
Code:
sudo /sbin/shutdown -h now
and I want to use only
Code:
sudo shutdown -h now
I want to change my user's path variable to make it equal to root's path. how to change it? I don't know many things of shell still.

Hereunder is an output from CLI (putty)
I understand that the system knows the java is in a wrong place but if I do java -version it finds it correctly. I don't know and I don't understand how do I need to tell the OS that the java is somewhere else, I just did that with export java home and java path but still dosen't work, it keep tells when I do whereis java "java: /usr/share/java"
Here is another output:
I'm having a strange issue with the PATH variable when running the command 'sudo su'. When executing this command the PATH variable changes. No problems there, but it changes to:
Code:
Looking at this, there are two weird entries (//sbin and //bin) which should both start '/usr' instead. I'm not sure how I've managed to change this, or how a piece of software I'm using has done it (more likely it was me I expect), but could anyone suggest which file to look in to correct it? If it makes a difference the machine is running CentOS 5.
I use this command:
Code:
find ./ -atime +360
to figure out the files that haven't been accessed since 360 days. The command above will return results like this:
Code:
/uploads/2010/02/some-file-name.ext
/uploads/2009/08/another-file-name.ext
... etc
I'm taking here about tins of directories, thousands of files. I'm looking to find a command that makes me able to move the results above to another path, and to create that path once it doesn't exist like below:
Code:
mv /uploads/2010/02/some-file-name.ext /old-files/uploads/2010/02/some-file-name.ext
But I want the executed command to create this path
Code:
/old-files/uploads/2010/02/
If it doesn't exist.
I am using CentOS5.5 & everytime it is showing command not found. If I export the path as below it will be working fine until a reboot. Again same error i.e command not found if I open new terminal. Every time I am exporting as below:
#export PATH=/sbin/:$PATH
#export PATH=/usr/sbin/:$PATH
#export PATH=/usr/bin/:$PATH
#export PATH=/bin/:$PATH
How can I set these permanently as that the paths should automatically be exported for everyone user whenever the system boots. And command completion also should happen for eg. #fdi (press tab), then it should show available options such as fdisk, etc.
I installed java in my pc by running the following on the shell
./jdk-6u24-linux-i586.
I need to set the path to the bin directory and also a new environmental variable JAVA_HOME.
I have bash. I installed Qt libs and want to set environmental variable PATH, I tried some stuff from qt tutorials..
Here is what i tried:
Code:
and it does nothing so i tried
Code:
then checked path

Now there are two issues
1) the make gives error that header not found( probably make don't have the path)
2) when i closed the terminal and opened it again the PATH I newly entered was not there !
I have a program that takes a relative path as input appends it to a some path string to get the actual path.
Now all I can input is the relative path. So if I want to go one level above my input will be ../mypath.
If I know the depth of the path used internally, I can use .. as many times to go to the root directory and then give the absolute path. But suppose I do not know the depth of the directory, can I construct a relative path string such that it considers it as a relative path. One way could be to have enough .. in the path string so that I can force an absolute path for some maximum depth of path.
Is there some path string syntax that I am not aware of but can achieve this?
I have a path c:windowsackup I need this string to be changed into /windows/back/up I used the command -bash-3.00$ echo windackup | sed 's/\//g' but the output is windbackup

I modified files in several directories, and need to run a diff on the backup I created before modifying the file.
I'm trying to compose a simple shell script to speed up the task, but getting a syntax error.
Here is what I have:
for i in DIR1 DIR2 DIR3 DIR4 DIR5 do;
diff /maindir/subdir/subdir/$i/filename.txt.old /maindir/subdir/subdir/$i/filename.txt;
done
I know the paths are valid, and if I run just the diff command with the actual DIR1 instead of $i it works.
I just set up an internal mail server for my office using Postfix, Dovecot and Squirrelmail. It works great except for one tiny problem. When I send mail, I address it to user@myoffice (no .com, .net, etc) and it works perfectly. However, somewhere in my work, I screwed up and for whatever dumb reason put myoffice.net somewhere in there and now the return-path always shows up as user@myoffice.net instead of just user@myoffice. Does anyone know how to fix the return-path so that when someone clicks reply it goes to user@myoffice? I've Googled and searched here without finding my answer, apologies if it's out there and I've just failed to see it. Rest assured I have done a couple hours of searching before finally asking for help.

I am trying to setup DNS domain name in my server (Fedora), which has static ip address.First, I put the DNS domain name in system-config-network->DNS->DNS search path. After restarting the network, it is deleted automatically.second, so I put the DNS domain name in /etc/resolv.conf as search mydomainname . After network restart, it is also deleted automatically.In both case domain name did not work (i.e, I can't connect to my server from outside using domain name, I can by ip address, internet is working fine).However, I found that the domain name is written in /etc/sysconfig/network-scripts/ifcfg-eth0 with search=mydominaname.

View 2 Replies View RelatedI have been trying to change my PATH environment variable to no avail. I am using Jessie i386 with MATE. Using my .bashrc file works but not well because with subshells the modifications get repeated. I want the change to occur on login.
I tried modifying ~/.profile ~/.bash_profile /etc/profile and /etc/environment and one or two others but in no case did my change get picked up even after logging out and in again and even after rebooting. I searched the Internet and found each of the above places to make the change but they don't seem to work with Jessie.
Where do I make the necessary change?
I want to add a path (/usr/sys) to the global $PATH. I will use this to test commands and scripts, which I don't want to be mixed up with regular commands. I've added the path to /etc/environment. When I start a terminal session under my user account, the path is included in the $PATH variable. However, when I start a root terminal, it is not. Is there a way to to change $PATH on one place where it will also affect the root terminal, or do I have to change it on 2 locations?
