Thread: How can I set Path in bash shell

hi,

I've installed JDK in Linux. As I'm a beginner to Linux, I need to how can I set path in bash shell so that all users can run java.

Use export command as follows at command prompt:

Code:

export PATH=$PATH:/usr/lib/j2sdk1.4-sun/bin

You need to add command to /etc/profile or /home/you/.bash_profile so that PATH get set automatically after each reboot.

You can also add variable JAVA_HOME

Code:

export JAVA_HOME=/usr/lib/j2sdk1.4-sun

I made this little script file that will change your path. it will add or remove a directory from your path. it is pathchanger. Here is a link

Hi. I'm a very very new linux user.

I am having the same problem of not being able to permanently adding a path to my bash profile.

I have already added the path to my .bashrc file, but don't seem to be able to restore the path after logging off from terminal.

This is how my .bashrc file looks like:

source ~/.bash_profile

export PATH=$PATH:/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

export PATH=/Documents/Camino/camino/bin:$PATH

export MANPATH=//Documents/Camino/camino/man:$MANPATH

Where the program i want to run is stored in folder called Camino.

Please help! =)

Thanks

Hello,
first, this is my first post at nixCraft, but long time 'viewer'. Thanks.

OK, I edited my .bashrc file adding

Code:

PATH=/home/landis/programs/Java/:$PATH
export PATH

to the end of the file. Everything else seems to be rem'd in the file.

Now, when I logout of KDE, logout of shell, login at prompt and type echo $PATH my 'new' path addition is echoed twice at the beginning of $PATH.. .
Why?
I did not add it anywhere else, nor was even One instance in path before I added it, that's why I added it.. : )

Спасибо,
Landis.
p.s., I also tried it without the line 'export'... same thing...

Hi,
can you once check PATH of Java in /etc/bashrc and .bashrc
you can use following command to check the same

PHP Code:

awk '/PATH/&&/Java/' /etc/bashrc .bashrc 


What OS are you using? Will all the users be using BASH? There are small differences between different distros.

ok, first try output:

Code:

landis@linux-amd:~> awk '/PATH/&&/Java/' /etc/bashrc .bashrc
awk: cmd. line:1: fatal: cannot open file `/etc/bashrc' for reading (No such file or directory)
landis@linux-amd:~>

hmm, same error as root (su).. Question.. do i need the ' (apostrophe) before and after /PATH/&&/Java/?
I used them. should I Not?

Landis.

I am using, on all systems a version of openSuSE from 11.2 to 12.1 and a bash shell.

Landis.
p.s., the system I'm on right now is openSuSE 11.2, but I think I was on a openSuSE 12.1 when I first asked the question.. but, again all my systems are openSuSE, bash. Thanks.

additionally, in bash, is it required to declare Every directory? I mean, is 'path' Not recursive?
if I have /etc/bin that does Not cover directories Below it (sub directories)?

Спасибо,
Landis
