Symlinks with spaces in folder name

The following works except for folders with spaces in the name.

#!/bin/bash
cd /var/packages || exit
while read -r link target; do
echo "link: $link" # debug
echo -e "target: $target \n" # debug
done < <(find . -maxdepth 2 -type l -ls | grep volume | grep target | cut -d'.' -f2- | sed 's/ ->//')

Like "Plex Media Server":

link: /Docker/target
target: /volume1/@appstore/Docker

link: /Plex\
target: Media\ Server/target /volume1/@appstore/Plex\ Media\ Server

Instead of:

link: /Plex\ Media\ Server/target
target: /volume1/@appstore/Plex\ Media\ Server

What am I doing wrong?

Assistance requested with a backup noscript for an Android tablet

BACKGROUND:

I have been endeavouring to update my Android tablet with different versions of this noscript and even before I set my mind on realising this noscript in particular and have been at it for quite some time, but I have so far not been completely successful. It is almost there.

My Termux Linux userland environment is a bit of a legacy ecosystem. I have tried to set up my system well, but there are anomalies and inconsistencies. I have just been teaching myself and learning on the fly.

In executing earlier versions of this noscript, it kept on maxing out the memory of my microSD, but there should have been more than ample space. The backup directories would be hundreds of times larger than the size of the original source directories. I realised it was infinite loops caused by nested symbolic links and probably other reasons that I have not yet identified. This is the reason for the structure of the noscript and the excessive logging.

The problems are few (I hope):

1. A virulent unbounded variable in the backup_files array. I just haven't been able to fix it and I don't know why.
2. I had a lot of problems with terminating all the spawned processes. Some of them were really sneaky. Hence, the KILLSWITCH. But I just can't get it to work and I don't know why.

How to make a symbolic link to file with exclamation point '!' in directory?

The file is located in:
/media/hdd2/video/Title 1!/noscript 1!.mp4

ln -sn "/media/hdd2/video/Title 1!/noscript 1!.mp4" "noscript 1!".mp4 results in:

bash: !/Title: event not found

Same output results when placing a single quotation around first exclamation point.

I add quote around the first exclamation point plus one backslash before:
/media/hdd2/video/Title 1'\!'/noscript 1!.mp4

ls -lh displays:
noscript 1!.mp4 -> '/media/hdd2/video/Title 1'\''\!'\''/noscript 1!.mp4'

When I instead just do a backslash:
/media/hdd2/video/Title 1\!/noscript 1!.mp4

ls -lh displays:
noscript 1!.mp4 -> /media/hdd2/video/Title 1\!/noscript 1!.mp4

Suitable projects to make using bash/linux POSIX commands?

https://en.wikipedia.org/wiki/List_of_POSIX_commands


I've created about 5 short noscripts. They're related to :



- SSL certificate expiry monitor and alert system

- Hangman trivia game

- Weather api redirection and check today's weather


and so on.


I want to indulge into something interesting now. I am a beginner (only 1 yoe with linux sysadmin and slowly starting noscripting)..

Someone suggested that I should write my own netcat? nmap? However, my interests doesn't lie there. I like to make games, guis, and and do data analysis using awk etc.

I like something that is practically applicable and suitable for bash as well. Something, I can use for real applications. SSL certificate expiry checker was one of them I really loved.

Changing color theme codes

Hello everybody. Sorry for bad format, just started to learn this stuff.

My google-fu has failed me, so i am asking for advice here.

I know how to set color scheme in tty, by adding something like

if [ "$TERM" = "linux" ]; then

\printf %b '\\e\]P0282a36' # redefine 'black'``

\printf %b '\\e\]P86272a4' # redefine 'bright-black'``

...

fi

or with echo

echo -en "\e]P0222222" #black

echo -en "\e]P8666666" #darkgrey

....

and i have added this to my .bashrc

But this method does not work for terminal emulators.

Closest i got was with

echo -ne '\e]11;#808080\e\\' # change background

echo -ne '\e]10;#000000\e\\' # change foreground

but i can not change color codes for other 0-15 colors.

I have also tried googh, but that just downloads theme profiles, and i cant save that in bashrc for portability.

Anyway. Any help is welcome.

How to style text with code?

How to style text with code? I've been using tput like this:

echo "$(tput setaf 1)some text$(tput sgr0)"

but I don't want litter the noscript with lots of call to the tput external command it seems excessive to fork/exec for such trivial things. Would like something more efficient and human-readable. Interested in solutions that are bash-specific as well as something that's more posix-compliant.

P.S. Is a small library of util functions worth using? Should you develop your own over time and work out kinks yourself or is there a public repo of well-written util functions that is "good enough"?

How do I pass multiple arguments to pandoc

I would like to pass multiple file paths to my pandoc noscript.

This is what I came up with:

TLDR: It looks for all files matching `01 manunoscripts/*/*` and puts them in a file separated by a new line. It then reads the file and adds each line to args. Then it gives the args to pandoc.

#!/bin/bash

# Create an output directory if it doesn't exist
mkdir -p .output

# Create an empty file to hold the list of ordered files
> ordered_files.txt

# List all unique file names inside the "manunoscript" folder, handling spaces in filenames
find 01\ manunoscripts/*/* -type f -exec basename {} \; | sort -u | while IFS= read -r file; do
# Find all instances of the file in subdirectories, handling spaces
find 01\ manunoscripts/*/* -type f -name "$file" -print0 | sort -z | while IFS= read -r -d '' filepath; do
echo "$filepath" >> ordered_files.txt
done
done

# Initialize an empty variable to hold all the arguments
args=""

# Read each line from the file a.txt
while IFS= read -r line
do
# Append each argument with proper quoting
args+="\"$line\" "
done < ordered_files.txt

echo $args

# Run pandoc on the ordered list of files
pandoc --top-level-division=chapter --toc -o .output/output.pdf noscript.md $args

# Open the generated PDF
open .output/output.pdf

# Clean up the temporary file

The problem is that pandoc is not recognizing the quotes around my argument, and treating the space between the quotes as separate args.

pandoc: "01: withBinaryFile: does not exist (No such file or directory)

The 01 that its refering to is the start of the path, 01 manunoscripts/blah/blah.md
^~~~~~~~~~~~~~~~~~~~~~~~~~
How could I pass dynamic amount of args into pandoc?

Avoid passing arguments to function until all items have been looped through ?

Hi,

I have the below part of a noscript which gets information from a system which the user inputs.

function rrupreparation ()
{
kubeworker=$1
charu=2024
timez=3

if -z $(ssh -q $kubeworker ssh -q $rruaddr cat /etc/benetel-rootfs-version)
currver=$(ssh -q $kubeworker ssh -q $rruaddr cat /etc/benetel-rootfs-version)
then
if [ $currver == $upgradever ]
then
echo "$rruaddr UPGRADED"
else
echo "$rruaddr NOT UPGRADED"
fi
fi
}

function rruchecks ()
{
kubeworker=$1
rruaddr=$2

if -z $(ssh -q $kubeworker ssh -q $rruaddr cat /etc/benetel-rootfs-version)
currver=$(ssh -q $kubeworker ssh -q $rruaddr cat /etc/benetel-rootfs-version)
then
if [ $currver == $upgradever ]
then
stat="(U)"
tval=TXMeanPower
else
stat="(NU)"
tval=tssi
fi
fi
echo "$stat | $currver | $kubeworker | $rruaddr
rrupreparation $kubeworker
}

function findnodes ()
{
findnodes1=1
for kubeworkers in $allkubes;
do
kubeworker=$( echo $kubeworkers | cut -c 6- )
echo $kubeworker
done
read -p "Find RRU in Worker : " kubeworker
for rruaddr in $(ssh -q $kubeworker arp -n | grep 10.42.8 | grep ether | awk '{print $1}')
do
rruchecks $kubeworker $rruaddr
done
}

findnodes

Script output once run

bai-ran-cluster-worker0
bai-ran-cluster-worker1
bai-ran-cluster-worker2
bai-ran-cluster-worker3
bai-ran-cluster-worker4
bai-ran-cluster-worker5
bai-ran-cluster-worker6

Find RRU in Worker : bai-ran-cluster-worker3 <--- User inputs any name from the above list

So in this case the user input is passed as arguments from findnodes function to rruchecks function which then checks the system, and gives the below result.

(NU) | RAN650-3V0.8.2patch2 |
NOT UPGRADED
(NU) | RAN650-3V0.8.2patch2 |
NOT UPGRADED
(NU) | RAN650-3V0.8.2patch2 |
NOT UPGRADED10.42.8.3510.42.8.3510.42.8.3610.42.8.3610.42.8.3710.42.8.37

In the above result the 1st line is the expected, the 2nd line is a result of the argument received in rruchecks being passed on to rrupreparation function.

How can I not pass the user input from rruchecks to rrupreparation until all systems have been checked in rruchecks ?

How to remove all directories that don't contain specific filetypes?

I've made a bit of mess of my music library and am sorting things with beets.io.

It's leaving behind a lot of cruft.

Is there a command I can run recuresibly that will delete all directories and files do not contain *.flac, *.mp3, *.ogg?

I've got hundreds of folders and subfolders much of which is just extra album art or *.m3u kinda stuff I would love to avoid manually going through them.

"sudo <command>" doesn't use system wide bash config.

I have created a system wide configuration for bash at /etc/bash.bashrc to format the prompt and source pywal colors so that I don't need to manage a separate config file for root and my user account. However, the colors are only applied when I run a command without elevated privileges. So, it works fine for my user account, and if I actually sign in as root before issuing the command; but if I were to type "sudo ls" while being signed in as my user, the text output remains completely white instead of using my color palette. Can anyone in here explain this behavior and would you be willing to tell me what I need to do to get it working correctly? Here are the contents of my /etc/bash.bashrc:

/etc
$ cat bash.bashrc
# If not running interactively, don't do anything
[ $- != *i* ] && return

# Grab colors from pywal
(cat /home/ego/.cache/wal/sequences &)
source /home/ego/.cache/wal/colors-tty.sh

# Prompt
PS1='\n\w\n\$ '

# Enable color output

Super simple question - How can I keep Neovim from opening if fzf is closed with <C-c>?

I have a simple alias which uses fzf to search for and open a file in neovim:

alias nv='nvim$(find . -maxdepth 1 -not -type d | fzf --preveiw="cat {}" --tmux)'

This works pretty much exactly as I want it to (although if it could be better I'd love to know how), but if I close the fzf using ctrl+c neovim will still open a new file.

This noscript is designed to be run in .bashrc so I get relevant info when I first sit down and open a terminal. After the first time it shows, new terminals will get a much more terse version so that it doesn't become annoying. That resets after an hour.

The noscript contains a way to make a header with figlet and run just about anything to the right of it. That was tricky to work out.
