Remove folder with special character on it - linux

I accidentally created some folders with special characters. I already read the other posts in stackoverflow, but don't work. When I type the ls -la command I see
root#mycomputer:/myfolder# ls -la
drwxr-xr-x 3 root root 4096 feb 6 17:53 ,

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.

Jenkinsfile ,by using sh, says No such file or directory, but it exists

I'm studying jenkins, trying to package a maven project to a war, then move it to a previously started tomcat webapps directory(/opt/tomcat/latest/webpass), but it reports 'No such file or directory'.
Already find out what causes this, but don't know why. Jenkins don't use the same filesystem as original?
Here is my troubleshooting:
1、I create a directory in my linux server under / as temp20190808.
2、then in jenkins file add sh 'ls / -l', there is no temp20190808,also the description of each file in ls form show differenly compare with original(there are details under).
3、using jenkins file, i create a file under / as jenkinstmp2019, then ls / -l, it's there, but after rm the code of creating jenkinstmp2019, then rebuild, ls / -l, jenkinstmp2019 no longer there, so the jenkins file system is a onetime job?
Here are code elaboration on point 1,2:
in my linux server, using ls / -l, there is a tmp20190808 i just created.

As you can see, it's like two totally different linux server, but it's the same one.
So i'm wondering whether jenkins create a temp virtual file server to execute it's job, so can't access to original file except it's own directory.

Find out the reason by myself.
The real cause is agent, i before used agent { docker { image 'XXX' } }, which makes jenkins run its job on docker image.Then i change it to agent any, so job will run on the server jenkins is deployed on.

`cd` to a folder in bash script not working: No such folder [duplicate]

This question already has answers here:
Why can't I change directories using "cd" in a script?
(33 answers)
'\r': command not found [duplicate]

Closed 4 years ago.
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:
mendel#DESKTOP-LIKG5E5:/mnt/c/Projects/chaverim-update$ 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.

OSX Homebrew /usr/local permisions for node

I have installed homebrew without any problems.
The problem was to install node.. I got permission errors about /usr/local directory and symlinks.
So I did
sudo chown -R myuser /usr/local
then I istalled node without problems and then I did
sudo chown -R root /usr/local
I don't remember how was the owners in first place. I just followed some suggestions from stackoverflow to change the owner of /usr/local (a voice inside me says I did bad).
So when I run
brew doctor
I got some warnings and suggestions to chown some folders in /usr/local directory, so I did them. Then when I run
brew doctor
brew update
I get no warnings or errors anymore and looks fine (there was no updates to do after all).
My directories now looks like below. Can anyone confirm if is secure like that? How should be the owners in /usr/local ? Tt's okay to have it owned by my user as they say at github? Thanks.

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
