r_bash

Using output from command(s) not as input for the next command(s), but AS the next commands. (For DNS lookups.)

Scenario:

I want to be able to immediately run DNS lookups (`host`) on modified output from another command that generates a list of FQDNs.

I have multiple FQDNs that I'm querying against for the generation of a custom hosts file.

E.g.

~$ ./generatehosts
host1.com
host2.com
host3.com
[...]
host1000.com

What I want to do is from that output get a list of IPs (preferably just to the right of the FQDN) the IPs they're associated with.

I noticed I can use \`sed\` to create:

~$ ./generatehosts | sed s/^/host /
host host1.com
host host2.com
host host3.com
...
hosts host1000.com

But how do I turn the output into the commands I want to run?

I'm 100% sure there is a less hacky and awful way to do this, but it got me curious if this was even possible.

Prepend text to every line of multi-line output

Been a while since I've done this kind of thing in bash, and my google skills seem to be failing me at the moment.

I have a command that returns multiple lines of results. I'm writing a noscript using that command, and would like to prepend some text to each output line, then write it to a file.

The desired output should look like this:

pretext output1
pretext output2
pretext output3

what I'm currently doing that is wrong (or at least, not right enough) is:

echo 'pretext 'commandwithoutput >> outputfile.txt

which results in:

pretext output1 output2 output3

Is there a way to get the desired output in a one-liner without an intermediate step?

I feel like this is something I already know how to do and am having some end of the day brain fog.

Batch noscript conversion to BASH

Hello everyone,

I recently had to retire my windows server that I was using to run some batch noscripts. One of them was used to create nfo files for my media server. I am not confident using bash, but I am hoping someone here can. Would someone please convert this noscript for me? Any help is greatly appreciated, and noscript is posted below.

@echo off
setlocal
for /r %%a in (.mkv .avi .mp4 .mov .wav .mpeg .mpg) do (
(
echo ^<?xml version="1.0" encoding="UTF-8" standalone="yes"?^>
echo ^<episodedetails^>
for /f "tokens=1, delims=-" %%b in ("%%~na") do call :gennoscript "%%c"
echo ^</episodedetails^>
) > "%%~dpna.nfo"
echo %%~dpna.nfo

)
goto :eof

:gennoscript
set "n=%~1"
:gt
if "%n:~0,1%" == " " (
set "n=%n:~1%"
goto gt
)
echo ^<noscript^>%n:&=^&%^</noscript^>

comma between files in a ls

It's the first time I'm doing a noscript and the goal I'm aiming is to put a comma between every file name listed in the result message of the ls command. I'm a transferred student in a course where every other students have 1+ year experience in programming but that's not my case, the teacher won't help me since it's basic. He said me to make a condition, and if the argument (the file name) is not the last, then type a comma, if it's the last filename, type a point. But I don't know how to make a condition, how to write something, just how to type a command in a .sh.



To put everything in a nutshell the goal is to make a noscript that act like ls, by using the ls command bt after each filename there is a comma. I doubt there's a tutorial for that on the internet, I'm still looking for but that seems to be pretty difficult without help. Have a great day :)

Advanced if statements.

So this is a tough one.

Im trying to incorporate multiple if statements, Where only 1 if statement is executed.

But I need to be able to see wich parameter(if) it took. So i can better enhance it.

This is my code.

Currently it executes all ifstatements if they are true.

c=2
d=15
body=30



if (( c >= 0 && c<= 3 && d >= 13 && d <= 30 && body >= 13 && body <= 30)); then
bash -c "echo 'Parameter 1 were taken'"
fi;

if (( c >= 0 && c<= 3 && d >= 5 && d <= 7 && body >= 18 && body <= 24)); then
bash -c "echo 'Parameter 2 were taken'"
fi;

if (( c >= 0 && c<= 6 && d >= 4 && d <= 6 && body >= 25 && body <= 30)); then
bash -c "echo 'Parameter 3 were taken'"
fi;

Backticks

So based on this post i've read that you should use || \

Should i Remove the fi and then statements and make it only as ONE "then" and "fi"?

How would i accomplish that when i want to know what parameter it took?

Help is appreciated.

cron delete command help

Hi all,



I am running this manual command to delete a kubernetes pod

kubectl delete pod -n testing-namespace tunnel-displace-665121cf-8c71y
pod "tunnel-displace-665121cf-8c71y" deleted

I was wondering is there a way to set it up in a cron job noscript or one liner to delete it, bear in mind that the pods ending name '665121cf-8c71y' constantly changes when deleted and a new one is spun up.

Help with recovering files in vim

I was working on a file in vim and I press :wq, I closed, but when I opened it again, I loaded stuff form some swap file (from 6 hours ago) so I lost all of my data.

I tried vim recover, but still, its loading only from the swap file from 6 hours ago.

Is there any way I can recover my data?

(Anything will work, like when I scroll up on my terminal, I can see prev data, but I does not go up to the point where I was working on my file, is there any way I can see my data this way atleatst?)



Any help will be appreciated (I have to submit an assignment in 6hrs and all my data was on that file I lost)
