I have a link for the repository file
https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/cloudera-manager.repo?_ga=1.139114810.807939978.1489498435
How can I download it? Which command should I use?

You can create server.repo file in following location.
cd /etc/yum.repos.d/
You can copy contains from above URL and save the file. After, you can install a package via yum command.

wget https://archive.cloudera.com/cm5/redhat/6/x86_64/cm/cloudera-manager.repo?_ga=1.118167936.807939978.1489498435
This is the way to download repo file. Now it seems very easy.

I have a project that is deployed by a previous dev on a linux server. The environment variables are stored in /etc/systemd/system/gunicorn.service. The file doesn't seem to be present anywhere in the server but still the code runs fine. There are multiple steps to get this file set up but none to read it. I need the information to get it running on my local machine. Any cli commands to read the same?
The directory is in format:
app.py
requirements.txt
README.md
The app.py is the main function and the rest 2 also don't have anything to do woth gunicorn.
Did you try:
sudo cat /etc/systemd/system/gunicorn.service

I am trying to add https://github.com/RubinLab/aimconvert to my /bin so I can run it like a linux command. How can I do this?
From the README, you can first execute it locally within your local cloned repository
git clone https://github.com/RubinLab/aimconvert
cd aimconvert/bin
./aimconvert xml2json inputDirPath outputDirPath
will convert every xml in inputDirPath to json and puts in outputDirPath.
Creates outputDirPath if it doesn't exist
I recommend testing it that way first, because the bin/aimconvert is based on a relative path:
#!/usr/bin/env node
require('../')();
So adding directly bin/aimconvert to your /bin might not work.

I made a directory in my ubunto desktop and copied some file inside it.
I tried to go inside the directory by using the terminal.
the issue I have is when I want to back to the parent directory which is "Desktop" by using "cd.." command I got an error says cd..: command not found
I'm a newbie and want to know the reason.
would you explain it for me.
thank you
You need space, after command cd
cd ..
You missed the space in between cd and ..:
cd ..
You are missing a space, should be cd ..

I downloaded tbb40_233oss_lin.tgz file from http://threadingbuildingblocks.org/ver.php?fid=174
I set "TBBROOT" variable to the directory in my bash_proflie and I unzipped the tar file and navigated to the bin folder and run tbbvars.sh file
I typed
sh tbbvars.sh intel64
I was trying to run examples but it complains as shown bleow
count_strings.cpp:38:37: fatal error: tbb/concurrent_hash_map.h: No such file or directory
I tried to set up the library path manually and I typed
g++ file.cpp -o output -L/path/to/the/lib/-ltbb
but it still complains.
How do I compile the sample code on Ubuntu?
Thanks in advance.
I installed it from the Ubuntu repository, and it works without any problems.
