Directory given in a variable gets never reached - gitlab

There are two variables in my .gitlab-ci.yml file, both of them are used in the same script line:
variables:
TEST_SERVER: 10.11.12.13
BUILD_DIR: "/var/www/distrib"
[...]
script:
- ssh skipper#$TEST_SERVER 'ls -la $BUILD_DIR'
The server IP gets picked up correctly, but the directory gets never reached (and it exists, of course). The directory contents listed below are obviously user's home dir contents:
$ ssh skipper#$TEST_SERVER 'ls -la $BUILD_DIR'
Warning: Permanently added '10.11.12.13' (ECDSA) to the list of known hosts.

I tried defining the directory variable with or without quotation marks, then calling it with double dollar sign ($$BUILD_DIR), but none of these attempts worked.
Any ideas what is wrong here?

I think the single quotes might be messing with the script section somewhat, as everything inside the single quotes is preserved literally.
Using double quotes round the ls should resolve the issue.
ssh skipper#$TEST_SERVER "ls -la $BUILD_DIR"

This is my entire script. it is simply to avoid having to type it again and again
cd api
rails s -p 3001 -b 0.0.0.0
cd ..
When I am in the directory of the script and run cd api it works just fine. However when I run the script via ./start_server It does not work. Here is the output of ls -al:

As you can see there is a folder called api at the top and the start_server script is set to have execution permissions.

Touch command. permission denied

I was able to connect to my school server via SSH. I had an assignment in which I was supposed to use the touch command to create a new file. Yet it keeps returning permission denied. Others were able to do the same thing. Though why do I keep getting this error?
Below is what was the input from the terminal.

EDIT:
Here is what I see after trying touch today in /home
So to try and create a new document in the root directory you need to be recognised as root. That means using the sudo command.
However for that you would need a password that you may not have. If you do perfect. But in any case I would not recommend adding files to the root directory.
Instead try the following:
cd home
touch today
This should work just fine and answer your question.
Still if you need/want to create today in your root directory try the following
sudo touch today
You will then be prompted for the root password that you can type (if you have it obviously)
In any case I suggest reading this which may be very helpful for you.
I wonder if this was ever truly answered.
If I was looking at it, I would try to see what the system thinks is the home directory of djaneka1, since it may have been setup partway and not completed, leaving stuff owned by root that should have been owned by djaneka1.
If you use the pwd command, and get back the "/" (root) directory there is something wrong with your setup.
The message: Could not chdir to home directory /u/d/j/djaneka1: No such file or directory
tells you it can't find your home directory.
-bash-3.2$ pwd
/
the command "pwd" revealing "/" is just an artifact of the system not being able to find your home directory.
To find what the system thinks is one's home directory,
one can search the file named '/etc/passwd' for one's login name.
I expect this is a possible result if you do that:
$ fgrep 'djaneka1' /etc/passwd
djaneka1:x:1505:1506::/u/d/j/djaneka1:/bin/bash
since it complained that it couldn't find that directory.
This needs to be fixed by someone who has more rights to the system, like root.
there is nothing djaneka1 can do a

I can't do anything with the ones pointed as question marks
I tried to type the command mv and then press tab and this is what I get
root#mycomputer:/myfolder# mv
,/ ▒/ 7/ h/
(/ ▒/ 8/ i/
[/ ▒/ 9/ j/
$/ ▒/
\/ ▒/
So apparently I can't rename them in order to delete them.
Any ideas?
What finally worked for me was one of the answers I found in this question:
rm all files except some
rm !(textfile.txt|backup.tar.gz|script.php|database.sql|info.txt)
If you don't need the other directories, you can just
rmdir ?
Or, use character class (supported e.g. in bash):
rmdir [^789hij] # removes all one-character directories except for 7, 9, etc.
You can also try mc or some other file manager.

CHROOT : Allowing outside access to chrooted users with mount bind

I have a chrooted user(username: clientdev) which I have jailed inside their home directory. This chroot directory is /home/clientdev/ which is owned by root.
Now I need this clientdev user to be able access the tomcat web application folder which is residing under /mnt/datadrive/tomcat/webapps.
What I have done is :
chroot the user with a public key of their own to the home
directory.
Create a folder under /home/clientdev called tomcat_ROOT and gave
the ownership to clientdev.
Now when I run the command :
mount -bind /mnn/datadrive/tomcat/webapps /home/clientdev/tomcat_ROOT
The folder disappears from the directory listing inside /home/clientdev if I login with clientdev. My root user can see it but now the desired user.
Any help would be greatly appreciated
Thanks in advance,
Peter

rotation of file in shell script

I need to write rotation of files shell script. I have following format data in a target directory(/backup/store_id/dates_folders)
Like :
cd /backup/
drwxr-xr-x 5 root root 4096 Mar 25 12:30 44
drwxr-xr-x 3 root root 4096 Mar 25 12:30 45
drwxr-xr-x 4 root root 4096 Mar 25 12:30 48
drwxr-xr-x 3 root root 4096 Mar 25 12:30 49
cd /backup/44/
drwxr-xr-x 2 root root 4096 Mar 25 12:30 22032014
drwxr-xr-x 2 root root 4096 Mar 25 12:30 23032014
drwxr-xr-x 2 root root 4096 Mar 25 12:30 24032014
drwxr-xr-x 2 root root 4096 Mar 25 12:30 25032014
now 44 (store_id) contain four dates folders. I want each store_id( like 44 folder) contain only three recent dates folder like 23,24,25 & 22 should be deleted. Please help me how to write in shell script. Please give me some hint
This should work:
cd /backup && ls -d */ | while read storeId; do rm -r `ls -r $storeId | tail -3`; done
I assume here that directory names are more important than their timestamps...
If that is not the case, you should use ls -tr instead of ls -r, to let ls command sort on timestamps...
