linux PATH not working - linux

I dont know why rbenv command do not work.. T^T
only work when 'cd /usr/local/.rbenv/bin && ./rbenv'

P.s: same steps work just fine on ubuntu 18.04
There are a lot of different ways to build libcurl with openssl support, and this may not be immediate to find out what is causing this issue.
But here is the procedure I am using on Ubuntu 20.04.1 - You may have to adjust the content of the CROSS_COMPILE variable, since you are using the arm-linux-gnueabi toolchain, and not the arm-none-linux-gnueabihf one: I am using the gcc toolchain for Cortex-A from ARM.
The versions of curl and openssl may have to be adjusted as well.

Thank you ..
I solve the issue ...
The problem is with zlib need to build it inside toolchain and add this in configure seetings
--with-zlib=$prefix/lib

[ec2-user#ip-172-31-38-218 opt]$ cd /opt/tomcatfolder/
-bash: cd: /opt/tomcatfolder/: Permission denied
Can you please help in resolving this above issue..?
I followed instructions of installing Tomcat from this link how-to-install-apache-tomcat-8-on-centos-7
It seems you are the ec2-user, but the directory is owned by tomcatuser and the permissions on the directory do now allow other users or groups to read it.
Try sudo chmod 755 /opt/tomcatfolder/ and then cd into it.
That will add read and execute permissions to the directory.

Strange file permission in docker container (question marks on permission bit and user bit)

I write a Dockerfile and docker-compose.yml to build a custom image which combines beakerx and cling, which contents are below.

ERROR: Service 'beakerx-cling-prebuild' failed to build: The command '/bin/sh -c ls -la /home/beakerx/.local' returned a non-zero code: 1

This problem is related to the storage-driver bug, see https://github.com/moby/moby/issues/28391, https://github.com/moby/moby/issues/20240. Currently I can only change storage-driver to overlay, use the default aufs or recommended overlay2 will break.
If you came here after you copied a file or folder with "docker cp" using docker-ce 17.x, you can simply resolve the issue by restarting the docker service (make sure it really was stopped) or rebooting the whole system.
I have had that issue a few times and usually the file was back to normal after a reboot. I read in this thread that:
If you improperly mount a filesystem, the mount point of that
filesystem may show up with question marks.
. 'you' means docker in that case and restarting the service "remounts" the storage layer.

Executing Karma giving permission denied error

I installed karma locally using
npm install karma --save-dev
and then i tried
$ ./node_modules/karma/bin/karma start
Then i get this error
vagrant#development:$ ./node_modules/karma/bin/karma start
-bash: ./node_modules/karma/bin/karma: Permission denied
vagrant#development:$ ls -liah ./node_modules/karma/bin/

54697 -rw-rw-r-- 1 vagrant www-data 50 Nov 15 02:43 karma
What can be the reason

Your ./node_modules/karma/bin/karma executable does not have execution privileges for your user. You can chmod it to give you the right privileges with:
$ chmod +x ./node_modules/karma/bin/karma
To avoid this in the future, simply install it with npm install -g karma-cli (globally).

Can't run npm-installed packages as user

Earlier this afternoon I installed Node.js on Fedora 16.
user#$ sudo yum localinstall --nogpgcheck http://nodejs.tchol.org/repocfg/fedora/nodejs-stable-release.noarch.rpm
user#$ sudo yum install nodejs-compat-symlinks npm
Then I installed a package with npm. Every package I've installed with npm on Fedora (this isn't my first time) has involved something like the following process. Read it and weep. Clearly, this is hackish and wrong, but when I decide to install less or any other npm package, I have to go through the same procedure. Why? What is broken about my environment or approach?
user#$ sudo npm install -g jslint
[... this works ... kind of]
user#$ jslint
bash: jslint: command not found
user#$ sudo su
root#$ jslint
No files specified.
Usage: /bin/jslint ... [works]
root#$ which jslint
/bin/jslint
root#$ ls -l jslint
lrwxrwxrwx. 1 root root 38 Jul 15 14:58 /bin/jslint -> /lib/node_modules/jslint/bin/jslint.js
root#$ cd /lib/node_modules; ls -l
...
drwxr-xr-x. 2 root root 4096 Jul 15 14:22 inherits
drwxr-xr-x. 2 root root 4096 Jul 15 14:22 ini

...
root#$ su user
user#$ jslint
o files specified.
Usage: /bin/jslint [now it finally works]
Recent versions of npm switch to user "nobody" as a security measure if it's being run with sudo privileges. Try doing global installs while logged in as root, rather than using sudo.
