How to: add directory to path

I've got no idea...  One difference I can think of is the search PATH used for commands might be different. (Causing the shell to traverse different directories when looking for the commands to run)

 

 

My cache_dirs lives in /boot/custom/bin.  I invoke it like this in my "go" script.  my drives spin down just fine.  I add /boot/custom/bin to the execution path in the "go" script.

(This is my whole "go" script.)

#!/bin/bash

# Start the Management Utility

/usr/local/sbin/emhttp &

PATH=$PATH:/boot/custom/bin

cache_dirs -w -e Pictures -e data -d 3

fromdos < /boot/custom/bin/powerdown > /sbin/powerdown

chmod u+x /sbin/powerdown

fromdos < /boot/custom/etc/rc.d/S30-inittab-powerdown | sh

fromdos < /boot/custom/etc/rc.d/rc.local_startup | sh

echo "/boot/unmenu/uu" | at now + 1 minute

I'm tring to figure out how to add a directory to the path but am having no luck.  I found this example from Joe L. which is the exact directory I want added to my path but when I copy this line into my go script it does not seem to work.  After rebooting /boot/custom/bin is not in my path.  What do I needto do in order to get this working?

The reason it does not work for you is that you do not run the "go" script when you log in.

A login shell gets its path from two places in linux.  a system wide file

/etc/profile

and a user-specific file located in the user's home directory

.profile

The system wide file is evaluated first, then the user-specific one.

The user-specific one does not currently exist in unRAID. If it did, it would exist as /root/.profile  ( .profile in the home directory of the user logging in)

To create the ".profile" file, we can add a line in the "go" script.  Then, when we next log in, ".profile" will be evaluated and your PATH set.

The line you need to add to the "go" file is:

echo "PATH=$PATH:/boot/custom/bin" >/root/.profile

Thank you, I would have NEVER figured that out on my own.

If I also wanted to use the next line, cache_dirs, shown in the go script would I need something like this then?

/usr/local/sbin/emhttp &

PATH=$PATH:/boot/custom/bin

echo $PATH >/root/.profile

cache_dirs -w -i Videos

/usr/local/sbin/emhttp &

PATH=$PATH:/boot/custom/bin

echo $PATH >/root/.profile

cache_dirs -w -i Videos

 

The second line needs to be

echo "PATH=$PATH" >/root/.profile

Otherwise, what ends up in .profile is a line looking like this

/usr/local/sbin:/usr/sbin:/sbin:./:/usr/local/bin:/usr/bin:/bin

instead of this

PATH=/usr/local/sbin:/usr/sbin:/sbin:./:/usr/local/bin:/usr/bin:/bin

No... close, but not quite

The second line needs to be

echo "PATH=$PATH" >/root/.profile

 

Otherwise, what ends up in .profile is a line looking like this

/usr/local/sbin:/usr/sbin:/sbin:./:/usr/local/bin:/usr/bin:/bin

instead of this

PATH=/usr/local/sbin:/usr/sbin:/sbin:./:/usr/local/bin:/usr/bin:/bin

 

AH!

Once again - THANK YOU

Hey sorry to dig this up from the graveyard, but I'm having trouble getting this to work. I have this in my go script:

PATH=$PATH:/usr/lib64/jre1.8.0_45/bin

echo "PATH=$PATH" > /root/.profile

And when I login, my .profile shows the correct path, but if I actually check $PATH, it doesn't contain the directory I added.

Am I missing some simple step?
