Need some help with bash to combine two lists

I have two lists (List-1 and List-2) as shown below.

How would I combine them two by corresponding volume id (see my desired output)

​

echo $LIST1
/dev/nvme0n1:vol020dae210a89ec02f
/dev/nvme1n1:vol04a2ddeb86823787a
/dev/nvme2n1:vol0e87fd7996e425e4c
/dev/nvme3n1:vol00835963bde10321b

echo $LIST2
/dev/sda1:vol020dae210a89ec02f
/dev/sdb:vol0e87fd7996e425e4c
/dev/sdf:vol04a2ddeb86823787a
/dev/sdg:vol00835963bde10321b

​

Desired output:

echo $OUTPUT
/dev/nvme0n1:/dev/sda1
/dev/nvme1n1:/dev/sdf
/dev/nvme2n1:/dev/sdb
/dev/nvme3n1:/dev/sdg

Appreciate your help ! Cheers !

Odd behavior with reading from stdin and then trying to read user input in a while loop

I successfully made a bash noscript that would make a centered list of files (images) then let you select an image interactively and it would display whatever image you would currently have selected, in the terminal using an image viewer.

It works well if I assign the array from within the bash noscript with

names=(fd . /home/sweet/Pictures/icons --extension jpg)
and then I would read the user input in a while loop that would let me move through the array in increments to select different files/images using 'j' or 'k'.

the problem Im having is that I want to be able to use any command and pipe it into my bash noscript but no matter which method I try, it blocks the user keys/input from being read. I've spent 5 hours trying every suggestion online that I could find and reading man pages but to no avail. Most of them would "work" to assign the piped in files to the array but then everytime I hit j or k it would just show up on the screen literally as an ascii character instead of catching the case statement and triggering the function to move up/down through the array, display the image and return to drawing the screen.

I tried simple things like names=$(cat) or

names=()
while read -r line; do
 names+=( "$line" )
done < "${1:-/dev/stdin}"

and "readarray -t names"

I also tried to take stdin, write it to a file and then read that file into the array. Below is the full code with some things commented out that I tried

Im trying to achieve a fzf like behavior where I can pipe images into the noscript, display them and then pick on option. Any suggestions as to how I can prevent read/stdin from blocking the ability to read user input would be amazing.

\#!/bin/bash

# move selection up
up() {
  if [ ${current} -gt 0 ]; then
current=$((current-1))
  fi
  tui
}

# move selection down
down () {
if [ ${current} -lt $((length-1)) ]; then
current=$((current+1))
fi
tui
}


# kitty
o() {
  kitty +kitten icat --scale-up --place 50x50@0x0 "${names[$current]}"
}

get_term_size() {
  read -r LINES COLUMNS < <(stty size)
}

indent() {
  for i in $(seq 1 $1); do printf ' '; done
}

# note this didnt work
# read from stdin by default unless there is an argument in pos 1
# names=()
# while read -r line; do
  # assign each item from stdin to the array
  # names+=( "$line" )
# done < "${1:-/dev/stdin}"

# This works by itself
# names=($(fd . /home/sweet/Pictures/anime-icons --extension jpg))

# length=${#names[@]}

tui() {
clear
for (( n=0; n < ${#names[*]}; n++ )); do
# n is the iterator, get word length and subtract by column size to center
wordlength=${#names[n]}
move_to=$(( $(( COLUMNS / 2)) - $(( wordlength / 2 )) ))
indent $move_to
if [ ${n} -eq ${current} ]; then
for i in $(seq 1 $wordlength); do printf '─'; done
printf '\n'
indent $move\_to
printf "\\033\[1m${names\[n\]}\\033\[0m\\n"
indent $move\_to
for i in $(seq $wordlength); do printf '─'; done
printf '\n'
else
printf "${names\[n\]}\\n"
fi
done
}

  quit='true'

  printf '\e[?25h'

}

&#x200B;

  printf '\e[?25h'
  exit
}

# get terminal size

Getting file path from an android device

I'm looking for a way to get the internal android path of an SD card from a device and assign it to a variable in bash.

For instance, when I browse my device connected to my pc, the entire working path is something like:

/run/user/1000/gvfs/mtp:host=motorola_Z38948/SanDisk SD card/Tunes

When browsing the same directory from the phone, it appears as

/storage/9028-e980-z73899-987/Tunes

As far as I can figure out (which probably isn't very far), there doesn't seem to be a way to list the latter path from the pc. So far I've been manually typing it into my noscript, but that's a terribly inefficient way to go about things, especially since the number (some sort of UID?) changes whenever the device is power cycled or the media is removed.

Any suggestions on how to retrieve the internal path for such detachable media via bash?

Where can I learn to use NNN as a noob?

What's a good tutorial on nnn for Mac. I'm a terminal noob, and installed the program. It's really fast and I love it for zipping around my folders and doing basic tasks. I've not managed to get previews however. I've spent quite some hours now with ChatGTP to get help but I mostly get inadequate, conflicting, or plainly wrong instructions. The learning curve is steep here as I'm looking at the instructions for installing preview-tui, and I can't quite get my head around it.

This is probably not the right forum for asking, but perhaps someone on here can point me in the right direction? Where can I get help with this stuff? Any advice would be appreciated.

Thanks.

Trying to use inotify + cp to move file upon creation.. cp can't reach source

Script:

#!/bin/sh
source='/var/lib/awx/projects/_*/files/'
dest='/var/lib/awx/proj_dep_files'
inotifywait -m --event create,modify,delete /var/lib/awx/projects/_*/files/ --format %w%f | while read path file; do
cp -f $path /var/lib/awx/proj_dep_files/
done

Error:

Setting up watches.
Watches established.
cp: cannot stat '/var/lib/awx/projects/_33__aap_repo/files/RPM-GPG-Key-cisco-amp': No such file or directory
cp: cannot stat '/var/lib/awx/projects/_33__aap_repo/files/debsig_policy': No such file or directory

cp: cannot stat '/var/lib/awx/projects/_33__aap_repo/files/snmpd.conf': No such file or directory

Now source and dest have been verified a few times.. perms on source and dest = are 777.I did try just an 'echo $path $file' earlier and the value of $path is the full /dir/path/to/file.name

​

And I can run the inotify and cp parts manually and they work so I'm totally struggle bussing it on this.

​

EDIT: I realize the source and dest variables arent doing anything.. with them I get the same error. This was one iteration of testing.

Creating a bash noscript to match multiline patterns in log files

Hi,


I'm trying to automate some time consuming tasks/log checking, building a system that I will replicate to other uses.


I have a logfile for example:


...multiline ACTION Text where all is good...
ERR-101 Something is wrong
ERR-201 Something is wrong with QASDASDASD
INFO-524 Something was wrong
WARN-484 Check line 23

...multiline ACTION Text where all is good...
ERR-101 Something is wrong
ERR-201 Something is wrong with PPOYOYOY
INFO-524 Something was wrong
WARN-484 Check line 23
INFO-524 This is it


I'm creating a check-error.template file:


# This is the template file
ERR-101 Something is wrong
ERR-201 Something is wrong with <TEXT_VAR>
INFO-524 Something was wrong
WARN-484 Check line <NUMBER_VAR>
<?>INFO-524 This is it</?>

Starting with # is a comment, surrounded by <?> are optional (e.g. exist only in the last line).
Text and number will be regexp checked.

If the error matches the template, I know it's ignorable.
I'm not using something advanced (perl, other regexp helpers), as it will be an issue to make sure it exists on every environment.


The following function gets a file and converts the template to regexp pattern

function template2variable {
local file=$1
local var_name=$2
local template=$(sed '/^#/d' "$file")
local pattern="${template//\\/\\\\}" # replace \ with \\
pattern="${pattern//\"/\\\"}" # escape "
pattern="${pattern//<TEXT_VALUE>/([[:alnum:]_]+)}"
pattern="${pattern//<NUMBER_VALUE>/([[:digit:]]+)}"
pattern="${pattern//$'\n'/\\n}"
pattern="${pattern//<?>/(}"
pattern="${pattern//<\/?>/)?}"
printf -v "$var_name" '%s' "$pattern"
}

template2variable "check-error.template" $error_template

Matching template with:

grep -Pzo "${error_template}" $logfile

Doing so, I get back all the template lines I wished.


However, when trying to work with the grep data
using -n lists every iteration with 1
using -c I get line count of 1
using -v results in an empty output


It seems like the match has returned as one giant result instead of several I can iterate over.


What am I doing wrong?
Suggestions for improvement?


Thank you

It seems one can't use FFMpeg sub-folder syntax, './', when specifying list of video/audio files to concatenate in a text file.

I'm in the folder, present working directory, /home/user/Documents/, and have 2 main folders:

File List Text Files
/Split Files/Subfolder/

The first folder contains a text file, FileList.txt, with a list of video I'd like to concatenate/merge into one sequence:

file '/home/user/Documents/Split Files/Subfolder/004.webm'
file '/home/user/Documents/Split Files/Subfolder/005.webm'

Alternatively they can be specified as:

file './Split Files/Subfolder/004.webm'
file './Split Files/Subfolder/005.webm'

The following statement is executed, to join 004.webm and 005.webm into the output file 004005.web:

ffmpeg -f concat -safe 0 -i "./File List Text Files/Filenames.txt" -c copy "./Split Files/Subfolder/004005.webm"

In Windows CMD, I could use, ./Split Files/Subfolder/004.webm, in FileList.txt, but on Ubuntu Linux, FFMpeg displays the following error:

Impossible to open './File List Text Files/./Split Files/Subfolder/004.webm'
./File List Text Files/Filenames.txt: No such file or directory

It's trying to combing the two directories into one, which wasn't the case with Windows 7 CMD.

How to hack LD_LIBRARY_PATH to use a recent bash from a Debian sid chroot

I try to get a more up to date version of `bash` from `LinuxMint`.

I have a `chroot` with `Debian Sid` in my box.

What I try to do in a `bash` wrapper noscript, early in my `PATH`

#!/bin/bash

From the chroot:

% ldd /bin/bash

Is it feasible?
