I made a CLI to use saved curl requests

I'm slowly going from using GUI apps to just CLI/TUI and while doing that I wanted to ditch Postman as the app I use to test my apis. Looked through a couple of them but none was what I wanted so I made this one.

I'ts called Curlier and it runs .sh files with the curl request inside of it. It's handy cause I can do whatever I want to the curl response inside my .sh file allowing me to just do curly <request_name> and getting the reponse parsed as I want (or whatever I want to do with it tbh).

Idk, felt like sharing it here for people to try it out, contribute and tell me what they think about it.

Kinda new to shell noscripting so be kind.

What's a Bash command or concept that took you way too long to learn, but now you can't live without?

For me, it was using xargs properly, once it clicked, it completely changed how I write noscripts. Would love to hear your “Aha!” moments and what finally made things click!

Is it possible that RSYNC lists all the directories to say that it passes for all of them?

Hello! (thanks to ~~goog~~... translator)
Is it possible that RSYNC lists all the directories to say that it passes for all of them to see if there was something inside them that has changed?
I clarify that I am using RSYNC with origin = Linux and destination (a pendrive) with Fat32.
and finally verbose say that the copy will be small weight something like equiv. to about 1 common.jpg (little transfer little copy).
See this screenshot for see the list o dirs with and without files into them...
of course I understand that dirs below are listed because they have newer files to copy, but upper them, the list is only of dirs.
https://imgbox.com/WoKhKR20
I am testing an SD formatted with Ext4 to try how RSYNC works with Linux origin and destination in both cases.
And in this case of a modest test with few test directories, when I do RSYNC, RSYNc does not list the directories, that is, it does not warn me that I pass through the directories of this small Linux Test Origin Destination (Ext4).
Thanks and greetings!

Script works locally not when curl is used

I have a noscript that requires a y/n response that works when run locally, but when I curl it it seems as if a random character is passed:

Script `test.sh`:

#!/bin/bash

while true; do

read -p "Do you want to proceed? (Yn) " yn

case $yn in
[Y] ) echo ok, we will proceed;
break;;
[n] ) echo exiting...;
exit;;
* ) echo invalid response;;
esac

done

echo doing stuff...
df -hT

Whenever I use curl like this:

`curl -sSL https://url.com/test.sh | bash -x`

Then I get:

+ true
+ read -p 'Do you want to proceed? (Yn) ' yn
+ case $yn in
+ echo invalid response
invalid response
+ true
+ read -p 'Do you want to proceed? (Yn) ' yn
+ case $yn in
+ echo invalid response
invalid response
+ true
+ read -p 'Do you want to proceed? (Yn) ' yn
+ case $yn in
+ echo invalid response
invalid response
+ true
+ read -p 'Do you want to proceed? (Yn) ' yn
+ case $yn in
+ echo invalid response
invalid response
+ true
+ read -p 'Do you want to proceed? (Yn) ' yn
+ case $yn in
+ echo invalid response
invalid response

It seems as a character is passed continually. What is going wrong here? I really have no idea. Same noscript locally and curl.

Need help running automatic command on terminal

As noscript says, first of all I am new to this. I need help (not sure which MacOS terminal I should even begin with- the basic one that it comes with, iTerm2, or Tabby)

I am trying to run a sha512 hash command that will generate a seed. But I need to do it automated- way faster than manually typing. I need to run the command about 100,000 times.

The command I need to use: echo -n "1710084026-4b0f5fc279ba41b3e6d6b73fb26b8b333a1c3b7963a4c5b03f412538596b440c-UYwqnEx6DT9L-Number: 50796" |sha512sum

Which generates the seed: 312e1a1f5e194adfa429fefc001d2d01ea41d96591ae9fbbd59ab7f04a541f4d658440163142908d97a6c083b37482ab6565d9d212a95c58fab9a19589244a41

Now, I need to also change the "Number" value each time I run the command, so the seed generated changes obviously. For example, listed above is "50796", and I would need to change each time, lets say the second number I would test next would be "40048".

That would give the generated seed of:
885120a467d71ec6e14964e9898eb2ac1c49060945665d74665564bf075bbf6919ef886f37d3843993452092bcbcd39945e4774f252edd3dbfc2c6f7823af890

I need to do this for about 100,000 different numbers, until I get the seed match I am looking for. I have 120 characters for the hash seed im looking for, but missing the last 8.

I don't even know if I'm In the right place to post this, or what subreddit to do. But I desperately need help with this.


So far, I have this:

\#!/bin/bash

start_number=0

end_number=100000

target_seed="30b842d3b1c1fcf6eb24bc06f64b7d9733106633bbd98c66bda1365466a044580d0a452500397252ff4d129d17404a5ee244e0c42bab5624e86a423a"



echo "Searching for target seed pattern in range $start_number to $end_number..."

echo "Target pattern: $target_seed"

echo ""



found=false



for ((num=start_number; num<=end_number; num++)); do

\# Generate the seed

seed=$(echo -n "1710084026-4b0f5fc279ba41b3e6d6b73fb26b8b333a1c3b7963a4c5b03f412538596b440c-UYwqnEx6DT9L-Number: $num" | sha512sum | awk '{print $1}')



\# Display progress every 1000 iterations

if (( num % 1000 == 0 )); then

echo -ne "Checked: $num | Current seed: $seed\\r"

fi



\# Check for match

if [[ "$seed" == "$target_seed" \]\]; then

echo -e "\\n\\nMATCH FOUND!"

echo "Number: $num"

echo "Seed: $seed"

found=true

break

fi

done



if [[ "$found" == false \]\]; then

echo -e "\\n\\nNo match found in the specified range."

fi


But I haven't had matches, or I am doing something improperly. Does anyone have any help they could show me or point me to the right direction? Thank you so much!

Efficiently delete a block of text containing a line matching regex pattern

File in the format:

General

StartWithLastProfile=1

Profile0
Name=default
IsRelative=1
Path=Profiles/default.cta

Profile1
Name=alicew
IsRelative=0
Path=D:\Mozilla\Firefox\Profiles\alicew
Default=1

Profile2
Name=sheldon
IsRelative=0
Path=D:\Mozilla\Firefox\Profiles\sheldon

How to delete entire block of text (delimited by an empty line) if line matches Name=alicew? It can be assumed there's only one unique match. So the file should be overwritten as:


General

StartWithLastProfile=1

Profile0
Name=default
IsRelative=1
Path=Profiles/default.cta

Profile2
Name=sheldon
IsRelative=0
Path=D:\Mozilla\Firefox\Profiles\sheldon

Preferably efficiently (i.e. requires only reading the file once) and in something relatively easy to understand and extend like awk or bash.

inotify use cases, generic app reloader responding to config changes

I'm looking for a way to automatically/efficiently do things when certain files change. For example, reload the status bar or notification application when their config changes. `inotify` seems appropriate for that, checking for changes as events instead of constantly polling with e.g. `sleep 1` in an indefinite loop (if the info you're looking to update changes rarely, the former would be much more efficient).

* Is the following suitable for a generic app reloader on config change and can it be improved? `app_reloader` is the most app-specific part of the implementation--some apps take a signal to reload the config without restarting the process, but the "generic" way would be to simply restart the process.

# This specific example is hardcoded for `waybar`, can/should it work for any
apps in general?

app_config="$HOME/.config/waybar" # App's dir to check for changes
app_cmd() { exec waybar & } # Command to start app

# Reload app. Usually means kill process and start new instance, but in this
example with waybar, signal can be sent to simply reload the config without
restarting the process
app_reload() {

killall -u "$USER" -SIGUSR2 waybar

# Wait until the processes have been shut down
# while pgrep -u "$UID" -x waybar > /dev/null; do sleep 1; done

}

while true; do
pgrep -u "$UID" -x waybar &>/dev/null || app_cmd

# Exclude hidden files sometimes created by text editors as part of
# periodic autosaves which could trigger an unintended reload
inotifywait -e create,modify -r "$app_config" --exclude "$app_config/\."

app_reload

done


* Is it a good idea to make heavy use of inotify throughout the filesystem? For example, checking `~/downloads` for when files complete their downloads (e.g if a `.part*`,`aria2`, etc. file no longer exists) and updating that count on the on the status bar (or similarly, do a `du -sh` only when a file is finished downloading, as opposed to status bars typically polling every 3-30 seconds).

* Also interested in any other ideas to take advantage of `inotify`--it seems heavily underutilized for some reason.

comparing 2 sets of variables?

My code is unfortunately not working. It appears that it is only looking at the last 2 variables:

for reference a matches b and x matches y. I am attempting to compare the first 2 (I want a and b to match each other) and match the last 2 (I want x and y to match) if either set does not match, I want it to echo "no match".

if [[ "$a" == "$b" && "$x" == "$y" \]\];

then

echo "match"

else

echo "no match"

orgsync - Keep your org files in sync across computers!

# orgsync

Hello everyone, after just 2 days of learning Bash I decided to get my hands dirty and start work on a project, one that would actually benefit me, and so I settled on orgsync. orgsync is a Bash CLI tool that makes it easier to keep my Emacs org files synced across devices, regardless of the OS type.

Initially, it started out from a need to facilitate syncing changes across my personal & work computers, both of which have different operating systems (MacOS & Windows), additionally, I recently had my work computer switched to a newer one, so I figured having an automated noscript that pulled my org repository and placed it in a previously defined location would be useful for future such cases.

Note that currently, on the Windows side of things, it only supports WSL, although msys support through Git Bash is something I want to implement.

The link to the repo is here: https://github.com/MiEdCaLe/orgsync

# Why?

Learning purposes, which is why it's in a very rough state and even though I realized halfway through that it might not be all that useful compared to just doing it manually, I learned a lot, and wanted to share it here!

Mass renaming and moving of files according to file structure?

Hi,

I have a bunch of videos organised like this:

Videos
> Friends
> Season 1
> ep1.mp4
> ep2.mp4
> ep3.mp4
> Season 2
> ep1.mp4
> ep2.mp4
> ep3.mp4
> Season 3
> ep1.mp4
> ep2.mp4
> ep3.mp4

Now I want all files renamed according to file structure and moved to parent directory, like this:

Videos
> Friends_Season_1_ep1.mp4
Friends_Season_1_ep2.mp4
Friends_Season_1_ep3.mp4
Friends_Season_2_ep1.mp4
Friends_Season_2_ep2.mp4
Friends_Season_2_ep3.mp4
Friends_Season_3_ep1.mp4
Friends_Season_3_ep2.mp4
Friends_Season_3_ep3.mp4

How can I do that?

text variable manipulation without external commands

I wish to do the following within bash, no external programs.

I have a shell variable which FYI contains a snooker frame score. It looks like the 20 samples below. Let's call the shell variable score. It's a scalar variable.

13-67(63) 7-68(68) 80-1 10-89(85) 0-73(73) 3-99(63) 97(52)-22 113(113)-24 59(59)-60(60) 0-67(57) 1-97(97) 120(52,56)-27 108(54)-0 130(129)-4 128(87)-0 44-71(70) 87(81)-44 72(72)-0 0-130(52,56) 90(66)-12

So we have the 2 players score separated by a "-". On each side of the - is possibly 1 or 2 numbers (separated by comma) in brackets "()". None of the numbers are more than 3 digits. (snooker fans will know anything over 147 would be unusual).

From that scalar score, I want six numbers, which are:


1: player1 score

2: player2 score

3: first number is brackets for p1

4: second number in brackets for p1

5: first number is brackets for p2

6: second number in brackets for p2

If the number does not exist, set it to -1.


So to pick some samples from above:

"13-67(63)" --> 13,67,-1,-1,63,-1

"120(52,56)-27" --> 120,27,52,56,-1,-1

"80-1" --> 80,1,-1,-1,-1,-1

"59(59)-60(60)" --> 59,60,59,-1,60,-1

...


I can do this with combination of echo, cut, grep -o "some-regexes", .. but as I need do it for 000s of values, thats too slow, would prefer just to do in bash if possible.
