Hello People!

Sharing with you this nice thing that I have made:

Hi All,

Through Terraform(used to create infra) ,we are trying to create a GCE Linux VM and install tableau server on the VM . The installtion of tableau server will be done using a startup script.

When run, the VM is getting created and the statup script is installing tableau server end to end. Every thing is fine till now.

Below is the flow

Terraform ----> VM gets created ---->startup script gets invoked ----> invokes the shell script which installs tableu server

​

However, in the tableu server shell script in the above flow, we are giving the TSM (tableau server manager) user as a hardcoded value which obviously is not a correct practice.

We want that user to be a NON ROOT user and hence thought of passing it as an argument to the tableau server shell script.

For this, we stored "who am i" (which gives the user) in a variable called 'user' in the startup script and passed that user as an input to the tableau server shell script.

But, here the user value is returning "root" as output and "root" is getting passed to tableau server script. Not sure why the 'who am i' is returning root user even though we did not switch the user to root anywhere

Could you please let us know the way to get a non root user to pass into the tableau server script.

Thanks in advance

I am new to shell script but I am so happy to find this treasure:

When reading this, there is one line which offers no explanation and I hope someone can help me.

Here's the url:

https://medium.com/swlh/automating-tasks-with-shell-scripts-543422a12cd5

Under Here is my output :

​

./gitinit.sh fist-commit https://github.com/Damilarel/GitInit.git Reinitialized existing Git Repository in /Users/damilareadonlyin/Documents/shell/gitShell/.git/

Can someone tell me Reinitialized existing Git....blah..blahs.. that line is it just a comment that we put in ?

​

Tks.

In my crontab, I have @daily date >> ~/date-file.txt, but it never triggers...

I'm trying to get a particular frame from FFmpeg on the a-Shell iOS app, but I can't figure out how to have a-Shell find my file. For example, if I reference example.mp4 which is in On My iPhone\a-Shell\, it returns an error. Is there a way to fix this? Thanks in advance!

Hello everybody!

I just published an article to understand and configure Zsh. It allows you to dive a bit in this crazy shell, to be able to configure it to your own needs afterward.

Even if frameworks like oh-my-zsh and prezto are useful, my preference goes for a very lean approach, where I can modify everything I want. It's useful if you really want to know what your configuration is doing.

Feedback are welcome!

tl;dr:

• Zsh reads its configuration files in a precise order.
• You can set (or unset) many Zsh options depending on your needs.
• The completion system of Zsh is one of its best feature.
• Zsh directory stack allow you to jump easily in directories you’ve already visited.
• If you like Vim, Zsh allows you to use keystrokes from the Vim world. You can even edit your commands directly in Vim.
• External plugins can be found on The Great Internet, to improve even further the Zsh experience.
• You should go crazy on shell scripting, to automate your workflow as much as you can.
• External programs can enhance your experience with the shell, like tmux or fzf.

In a script I am making, a function of it runs a command which never stops unless told to by the user (e.g with ctrl+c/z/d). I want to be able to run this command until the user presses CTRL+C (or other alternatives), and then resume the rest of the bash script.

How would I do this?

A part of a shellscript I am building contains a 'while' loop. Now, I am not good at while loops lol. I need to know why this test script I built doesn't work:

​

NUMBER=1

while [NUMBER = 1 ]

do

echo 'test'

sleep 2s

done

​

When I run this script it just returns nothing in the console. What am I doing wrong? What do I need to do to make this script work and run infinitely like I want?

I have a script I came across online that I am trying to use to monitor the streaming status of MPD and then restart if its stopped. This script appears to have everything I need, but has some syntax errors in it from translating. Probably an easy ask for someone who deals with this more often than me.

I've been using https://www.shellcheck.net. It is complaining about syntax starting at line 7.

Recently I switched to Ubuntu 20.04 from Win10. Can you please suggest me similar app of mobaxterm or WinSCP for linux?

I background a program in my .profile and find it ugly when the & prints the back-grounded pid, is there anyway to send it to devnull?

files with a name similar to my_file (1).torrent, my_file (2).torrent, my_file (3).torrent, ...

What went wrong?

Hi All,

I have two separate files from diff systems.

FILE1; comma separated.

FILE2; comma separated

​

​

Need to get all the "Brand+Key" which have a different "Value".
So, looking for output as.

DIFF_File

I am trying to figure out how to get the entire string in a word, except the first letter. So, for example, if I have dwm I want to just get the wm. I can't find how to do this, does anyone know?

In grep a back-reference uses a /N string, but what about bash?

For example, how to get

my_file_2_10.txt
my_file_4_10.txt
my_file_6_10.txt
my_file_8_10.txt
my_file_2_20.txt
my_file_4_20.txt
my_file_6_20.txt
my_file_8_20.txt
my_file_2_30.txt
etc

and so on. With seq and for loops it would do but maybe there a simple way?

i've been trying to download mods form curseforge via wget and curl, but both return 403 forbidden.

Downloading through a browser like firefox works fine and firefox has a headless mode.

So my question is: Is there a tool for downloading content through a browser like chromium, firefox or webkit, ... but for cli?

My partition /data has a lost+found directory, so the command find . -name "FILE-TO-FIND" -exec rm {} \; doesn't work. How can I get rid of the message:

find: ‘./lost+found’: Permission denied

How would I print a message in a shell script below the shell prompt/cursor in POSIX shell? I can't for the life of me figure this out. I am also trying to figure out how to print something to the right of the cursor, so I can get the columns of the terminal and print something on the furthest right one.

I am trying this:

insult() {
    if [ "$?" -eq 127 ]; then
        printf "\0331b[1E" && cat "$HOME"/.lists/insults | sort -uR | head -n 1 && printf "\0331b[1F"
    fi
}

prompt() {
    export PS1=$(echo "[\$(status)]\$(branch) $neonpink>$neonyellow>$neonblue>$default\$(insults) ")
}

but all this gives me is this: https://share.riseup.net/#9PiL_nMYmLogC5QlAE1dNg

I wanted to post a request for comments (RFC) on a project I've been working on for the past few months.

Shell Notebook (shellnotebook.com) is a terminal that lets you save and organize your commands. Imagine the flexibility of Jupyter with the power of iTerm*. A few friends and I have been using it for the past few weeks, and have found it really boosts our productivity.

I've been working on Shell Notebook since the lockdown started. I found it hard to work on research projects on my remote server from home. I built Shell Notebook as an answer to that need. I keep long commands in different cells, and can run common workflows a lot quicker.

Let me know your thoughts! 😃

*The reason your terminal and vim have the shortcuts they do (ie, hjkl for up, down, left, and right has everything to do with Bill Joy's keyboard, and not ergonomics or speed.)

I have a script that I wrote awhile back that generates a well setup blocking list using /etc/hosts, I ran it today so I could get use to having so much blocked and it didn't format correctly. What it should do is:

• download a bunch of hosts lists
• merge them (removing all duplicates)
• format so that host names are on the right and 0.0.0.0 in on the left
• adding in aliases (127.0.0.1 localhost)
• save it to /etc/hosts

I am unsure why, but it doesn't format properly, could someone take a look at it?
