I made a terminal based password manager

Hey everyone!

I’m excited to share Vaulty, a lightweight, terminal-based password manager I’ve been working on. It’s open-source, secure, and super easy to use right from your terminal.

https://preview.redd.it/o08870yq265d1.png?width=2048&format=png&auto=webp&s=b346c3b8116d18357ef05fdcfcacc5c8eb3b1c18

**Why Vaulty?**

* **Simple & Secure:** Uses AES-256 encryption and a master password for protection.
* **Local Storage:** Keeps your passwords on your machine.
* **Password Generation:** Create or generate strong passwords.
* **Idle Timeout:** Auto-exits after 2 minutes of inactivity.

**How It Works:**

1. **Setup:** Create a master password on first run.
2. **Add:** Save new passwords with a website name and username.
3. **Retrieve:** Look up saved passwords by website name.
4. **Update:** Change usernames or passwords.
5. **Delete:** Remove old entries.

**Tech Stack:**

* **Bash Script**
* **OpenSSL for AES-256 Encryption**
* **Clipboard Support** (requires `pbcopy` on macOS)

**GitHub:** [Vaulty on GitHub](https://github.com/arturfriedrich/Vaulty)

I’d love to hear your feedback and suggestions. Feel free to contribute!

Thanks for checking out Vaulty!

Writing auto-update noscript for my VMs. Need advice

So recently, I've been trying to noscript more and get my github filled out for better job opportunities. I currently run a proxmox 8 hypervisor with several VMs. I've been working on a simple noscript to ssh in and run updates then reboot. My issue is that when I set up these VMs, I disabled the root account so that isn't an option right now. OS being used is Proxmox 8 and for the VMs it's Ubuntu server 22. I got my rsa key to login automatically on my VMs but I haven't been able to find a way to translate that into a password-less update command.

#!/bin/bash

#List of Servers
# 1:Network 2:Plex
srvlist=( "255.255.255.255" "255.255.255.255" )

#Admin login credentials
uname=<USERNAME>
pass=<PASSWORD>

#Update each server in order in srvlist
for server in ${srvlist@}; do
echo "Working on $server"
echo $pass | ssh -tt $uname@$server "sudo apt-get update && sudo unattended-upgrade && sudo reboot --now" 1> /dev/null
done

This is what I currently have written. It works, but I don't like that I have to keep login credentials in plain text. Sure, it'll be located in a read protected location only root has access to, but it still makes me feel weird to implement. My question is, how do I do this better?

sed -- change line only immediately after string match?

[foo]
value=horse

[bar]
value=horse

[baz]
value=hearse

Can I use sed (or another command-line tool?) to change only the second (the one in section [bar]) value?

need help with a grep noscript please

Hello everyone,

I am working on a weather project, and I have a .json file containing 5-day forecast information that I am trying to get specific information for 3 days from. I have 3 bash noscripts (bad noscripts) for tomorrow, the day after, and the day following. Each is meant to search the .json file and extract the weather icon code for that day. The .json file contains information in this format:

"dt_txt":"2024-06-08 06:00:00"},{"dt":1717837200,"main":{"temp":92.1,"feels_like":87.94,"temp_min":81.09,"temp_max":92.1,"pressure":1015,"sea_level":1015,"grnd_level":922,"humidity":16,"temp_kf":6.12},"weather":[{"id":800,"main":"Clear","denoscription":"clear sky","icon":"01n"}\]



there are 6 or 7 different entries for each date. All I want from the noscript is to read the first instance of any given date, and get the icon code from there. In the above case, "01n" is what I am looking for.

I cannot noscript and have spent many hours now with code generators that cannot successfully code this. What they produce keeps going deeper into the file and grabbing info from I don't know where.

Can anyone provide a working noscript that gets the information I am looking for?


Thank you for reading,

Logan

Bash history across different terminal sessions.

I use tillix for having multiple terminal windows open. After using different commands in different terminal windows, I checked bash history and it shows only some commands.

I thought bash history is tied to the user and not to the terminal session. What’s the probable explanation as to why not all the commands from all terminal sessions show in in bash history? I am using popOS!

Script stops when a command is run

I'm trying to run a bash noscript during which I move to a directory to run the “npm audit” command. This command seems to stop the execution of the current noscript.



The command :

npm audit --json > “$OUTPUT_FILE”

I had the same problem on Windows. The solution I found was to run the command in another instance of cmd using the command :

cmd /c npm audit --json > “%OUTPUT_FILE%”



The bash equivalent seems to be :

bash -c “ npm audit --json > ‘%OUTPUT_FILE%’

But that didn't change anything. Does anyone have any idea what's wrong?

Select output by line similar to previous commands

Just like you can use the arrow keys to scroll through previous commands, is there a way to do the same for each line of output? So I don’t have to copy or type a certain value from a list of values every time I want to use it in my next command.

mkdir with variables

I'm backing up my movie collection to my Plex server, which is running on Ubuntu Server LTS 22.04

I'm trying to write a bash noscript to create the directory and move the files over.

This is my code so far:
```
#!/bin/bash

movie="[Movie name] ([Year]) - [resolution] {imdb-[IMDb code]}"
file=$movie.mp4
path="\"/mnt/usb1/Movies/$movie\""
mkdir $path
```

But I get an error whenever trying to run it because it tries splits the directory up to a new one whenever it encounters a space, despite including double quotation marks in the "path" variable.

*The text in square brackets is only like that for the purpose of this example

Where am I going wrong?

Cannot kill process 684 even with -9 option as sudo. Why is this the case?

ubuntu@ip:~$ ps aux | grep configurable-http-proxy

When I ran the command, nothing happens. I ran the ps command again and I still see the process as active. Not sure how to kill it.

Weird exit status behaviour.

I thought by default, when bash's exit builtin fails, it will not alter the current exit status. Confirmed by these cases:

$ bash -c 'exit 14'
$ exit 1 1
$ echo $?
14
$ :|exit 99
$ exit 2 2
$ echo $?
99

However, the behaviour is different when there was no previous command, in other words, in a newly spawned shell (where the initial exit status is 0).

$ exit 42 42
$ echo $?
1

Why does that happen? And more importantly, what could be the rationale behind this?

Also, somewhat related, exit's argument handling is weird. It only fails (and doesn't quit the current shell) when the first argument is a valid 64 bit number (up to leading&trailing whitespace) and there's at least one other argument (any string) after it. However, when the first argument is not numeric according to the aforementioned rules, it doesn't matter how many arguments you put, it will print an error and exit. It also doesn't quit the shell on --help as the 1st arg, however, this does set the exit status to 2.

bash noscript `sed` help

Hello, I am a college student working on a summer project, but I feel like I have been stuck for too long on this one thing.

**TLDR:** I am working on a bash noscript and am having issues with \`sed\` not putting markdown for an indented bullet point in front of the line for any ports it finds.

So I am trying to work on a bash noscript and I have been stuck on part using \`sed\` for two weeks, so I come to you all for help. So I am trying to search through an nmap scan that I have happening earlier in the noscript, and add the markdown for an indented bullet point to the port lines. If I understand correctly I should be able to use regex as the searching pattern in \`sed\`, but I have been able to get every other thing I need working except for this one.

I will put a bunch of lines I have tried at the bottom so maybe you can see my thinking/attempts, but I have 2 different theories as to why what I am trying isn't working. Oh, and with the fun 3rd theory of me missing something simple and obvious.

1: I believe \`sed\` looks at \`\*\` as whatever character is right before it? So maybe because I am using that as my bullet point markdown it's thinking its a space? But things still don't seem to work when I replace it with a \`-\` instead?

2: I am missing something about what's needed to add regex into sed. Nothing too fancy here, I think I have tried the right (~~various~~) arguments. On its own I am pretty sure that my regex is right as I can verify that on its own.

Here are a number of the commands that I have tried so far

\`sed -e '/\[0-9\]+\\/\[A-Za-z\]\[A-Za-z\]\[A-Za-z\]\[\[:space:\]\]+open/gm/$\\t \* \\/'\`

\`sed 's/\[0-9\]+\\/\[A-Za-z\]\[A-Za-z\]\[A-Za-z\]\[\[:space:\]\]/\\t \* &/'\`

\`sed -e .....; /\^\[0-9\]\\{1,5\\}\\/\[a-z\]{3}$/s/\^/\\t \* /;\`

\`awk '/\[a-z\]\[a-z\]\[a-z\] open|\[a-z\]\[a-z\]\[a-z\] open/ {print " \* " $0}' /home/$ownerAccount/Desktop/$projectName/AaFinalDoc.txt >> /home/$ownerAccount/Desktop/$projectName/BbFinalDoc.md\`

This project is larger than anything I have tried before and because its fun I just keep adding to it after I finish the previous goal. I have historically been really bad in my programming classes but this feels fun so I don't want to give up!

I appreciate any help that any of you can give me, thank you!

EDIT: warrior0x7 pointed out I dont actually show my start and end goals, so here is an example that hopefully might help.
