CSV to variables

I'm trying to parse a csv to variables to use it in "update all wordpress/nextcloud/..." noscripts

The CSV looks like this:

nicename,application,directory
blog1,wordpress,/var/www/wordpress1
blog2,wordpress,/var/www/wordpress2
cloud,nextcloud,/var/www/nextcloud

How do i parse these into variables like $blog1.directory (using the nicename)?

Made a noscript manager for non-savvy users

Hey there,

​

I work with a lot of field techs, skill levels on computers vary. We have a bunch of various noscripts that we need the techs to run, but some have a hard time staying organized.


I made this so that there is a single folder, where all the noscripts reside. You only have to open this single "app" if you call it that. From there, they can run multiple noscripts with an interface.

​

I couldn't really find anything like this, so I made it.

​

Thoughts on improving? Also feel free to use it.

Question about calls with relative paths

The following is a call with an absolute path specification that works for me. This call, opens the file samplefile with the editor xed:

xed /a/b/c/d/e/f/g/samplefile.txt

Suppose I open a terminal and type the following:

cd /a/b/c/d

How would I then have to open the text file with the editor xed from this position with a relative specification. For example the following call I tried seems to be wrong here:

./e/f/g/samplefile.txt

Issue with sorting grep results in bash noscript

I do not know how to get my bash noscript to produce the right output, but it's very close. I need it to sort from highest frequency codon to lowest like this for an example correct output:

aac 20

aag 9

cgg 2

It's a dead-simple noscript that only installs some packages and generates proper locale and sets the time and date, but I guess it could still help new users.

N00b question

This is the noscript I'm using.

Now, I'm supposed to replace every instance of RAW_FILE with the actual path to my file. I'm having trouble with this. I've tried single quotes, double quotes, a space between the parentheses, and none of them work. Let's say the file in question is called file.xyz for example, how would I reference it? Note that the file is in the same directory as the noscript.

using grep in noscript

I am trying to write a noscript that will list a directory's contents and use grep to filter for only certain match sub directories and files. While the grep command works in command line fine when I put it in a noscript it no longer gives a return just holds up the noscript causing me to have to Ctrl-C out of it. I'm now a brand new noscripting guy but definitely a novice. I am on a Linux Machine attempting this. Any assistance would be greatly appreciated.

Need assistance for bash noscript

I have a noscript i am writing which lists directories or files in a location and displays them as selections to choose from. Once Chosen I would like to copy the "file" or "directory" to a new locations keeping all the contents. The copy part is goofing me up I cant seem to figure out how as when I am listing the choices its saving the full directory path PLUS a ":" sign. All I need is the full path call out and then a way to copy to a new given location. This noscript is being written on a linux machine.

Following is what I have thus far.. its proving challenging but ive been working on this for 4 hours just to get this far... I know the final line does not work.

#!/bin/bash

echo "Please select the item from the list"

files=$(ls /home/mib2/WorkTest/20230331*)
i=1

for j in $files
do
echo "$i.$j"
file[i]=$j
i=$(( i + 1 ))
done

echo "Enter number to select"
read input
echo "You selected: ${file[$input]}"

cp -R "${file[$input]}" /home/mib2/WorkTest/WWW/NEW1/

Writing a noscript that adds numbers to the end of a text file full of words

I am trying to write a noscript that adds numbers to the end of a list of words. Here's what I've tried:

#!/bin/bash
# add_numbers.sh

while read w; do
echo ${w}{0..9}
done

Then I run it with `$ ./add_numbers.sh < words.txt`

This runs, but it adds the numbers on the next line down, I think:

9 ZOOS
9 ZORN
9 ZOROASTER
9 ZOROASTRIAN

&#x200B;

So I tried to strip the carriage return (right?) at the end of the line when `read` gets the line:

#!/bin/bash
# add_numbers.sh

while read w; do
stripped=echo ${w} | tr -d "\r"
echo ${stripped}{0..9}
done

But the output just gives errors:

./add_numbers.sh: line 4: $'AGGLUTINATE\r': command not found
0 1 2 3 4 5 6 7 8 9
./add_numbers.sh: line 4: $'AGGLUTINATED\r': command not found

&#x200B;

What am I doing wrong?

&#x200B;

EDIT: For the heck of it I asked GPT3.5 to do this and here's what I got:


#!/bin/bash

while read line; do
for i in {0..9}; do
echo "$line$i"
done
done < "${1:-/dev/stdin}"

I left out the stdin redirect at the bottom, but what it outputs replaces the first character with a number in each word:

9ULU
0ULUS
1ULUS

Those lines would be ZULU and ZULUS.

Noobie BASH help

Hi -

New to BASH noscripting and need some direction.
I have this noscript below, but it's not creating the file i'm after. I think its related to path name for the new file location.

The error i'm getting is:
Start time: Sun, 02 Apr 2023 15:05:17 GMT
Stop time: Sun, 02 Apr 2023 15:05:18 GMT
Current status: 0 (Normal)
Standard output/error:
/bin/bash: line 15: Scripts/test/20230402-150518.txt: No such file or directory
Text file created at: Scripts/test/20230402-150518.txt

But no file created. I think i have the path name wrong, but not sure how to format it?

I think this is wrong.... folder_path="/Scripts/test"
but i'm not sure "why" its wrong.

&#x200B;

Any help appreciated-

What constitutes a "debugger enabled version of bash"

Hello.

Just for the hell of it for now, but it may be useful in the future, to have a gdb-alike front end for debugging bash noscripts, I think it is more pleasant than just a DEBUG trap.

Right now, I'm getting feedback indicating that `bashdb` isn't installed, but I also get the message:

warning: cannot start debugger; debugging mode disabled

So, I'm in doubt whether it is:

* A special version of bash, built for supporting [bashdb](https://sourceforge.net/projects/bashdb/files/bashdb/).

* Having a properly installed version of bashdb.

* One of the above in combination with `shopt -s extdebug`.

And I won't take further action, before I understand what that means.

I haven't installed `bashdb` yet. I can't find a debugger enabled version of bash in the `apt` repository, so, I wonder if I ultimately have to build a debug-enabled bash version myself. :)


Thanks!

How to differentiate between output and information in bash noscript

Sorry for the terrible noscript but I really couldn't think of anything better.

I have a bash noscript that uses echo to print some information about the execution context and then execute a command with said context.

I want to take the output of that command and save it into a variable or pipe it into another program.

The problem is that the contextual information is also considered as part of the output.

In PowerShell I can use Write-Host and Write-Output to differentiate the two.

Is there something similar in bash?

Example:

$ ./terraform.sh env output -raw some_value
Environment 'env' running on '<AWS region>'
a_very_useful_information

Obviously I want to save the output in a variable and be able to use it somewhere else without the information line printed before.

bash behavior with nested parentheses?

Is there a (documented) reason why I can use for i in sd[abc]; do … , done and get correct values of sda, sdb, sdc, but I can't use for i in {sd[abc],mmcblk0}; do … , done because I only get sdaabc and mmcblk0, not sda, sdb, sdc and mmcblk0?
