General :: PATH Variable - Command Not Found On New Terminal
Aug 3, 2011
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 tried to install JRE to my remote Suse 11 SP1 linux.After i finished with files i typed like
export PATH=<my jre path>
now i have no bash commands - typing ls causes
-bash: ls: command not found
i think that i should re-export my PATH to the right value but i don't know what it should be. I tried differend values
/etc/profile
/usr/bin

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?

I logged into my Red Hat Enterprise Linux machine at work (use it for software development) and the primary GUI does not load. Instead, widgets appeared for xclock, xterm, and Firefox. In the terminal, I start typing in commands to try to figure out what's going on, but all commands are not found except pwd and echo. I 'echo $PATH' and that returns just an empty, blank line. 'echo $SHELL' lets me know I'm using cash.
The likely cause was my attempt to install Adobe Reader Firefox plugin yesterday. After it downloaded, I ran the binary but Firefox didn't seem to recognize that I had installed it, so I went into my .cshrc file and added the adobe folder to the path. That didn't seem to work, so I gave up, deleted the binary and the folder I installed to, and removed that directory from the path in the .cshrc file. This last thing (the export PATH line in that file) I'm certain is back exactly as it was before.
I have successfully added the /bin and /usr/bin back to the path from command line via
setenv PATH /usr/bin:/bin
but of course it doesn't stick after reboot nor does it magically load the primary GUI. I'd rather not go through the effort of creating a ticket for our company's Global Service Desk cuz there's no telling how long that could take to resolve. In the meantime, I can't do any programming.

As you can see, /usr/local/bin is in the path. However, bash does not look for nasm in /usr/local/bin.

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.

What steps have to be followed for having customized contents of PATH environment variable whenever new users are created? I require this in order to include a special directory into PATH variable; and this has to be a default one for all the newly created users.

I have downloaded java and installed it with chmod +x and then ./bin package.
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 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.

As soon as I launch terminal I get the following:
[...]: command not found
[...]: command not found
And it then goes to a $~ prompt as usual. How do I make it so the two commands it is trying to launch don't run upon launching terminal?

I'm using lucid on both my laptop and my desktop, both fully up to date. When I ssh from my laptop to my desktop, I get "PATH: command not found", and then a shell with no working path. I don't know enough about how bash starts up, or how ssh works, to figure it out.
Update - I've found .bash_profile, and commented out the first line, and now it works. I'd still like to sort this, though, so I don't have to keep commenting it in and out. The line is: export PATH=$(PATH):/usr/share/android-sdk/tools

Usually in Gnome, under Ubuntu, the terminal command I use is:
Code:
gnome-open (path)
In most cases, I won't know the path and I'd rather not search for it with:
Code:
locate (file name)
