Cannot match character limit with regex

I have a bit of regex I'm struggling with and cannot seem to get it to only allow up to 20 characters.

I want it to match either with max of 20 characters in length:

test
test-123


I do not want it to match:

test-
-test
test-123-


This is what I have:

^([A-Za-z0-9]+)([-A-Za-z0-9]*)([A-Za-z0-9]+).{1,20}$'

What's wrong with this?

bash noscript to send disk usage telegram alert

Hello, I have found this interesting noscript googling but it gives me error on line 12 ans 18 percent not found and let not found. Can someone help me fixing it ?

#!/bin/bash

USERID="XXX" #Chat to u/getidbot
KEY="XXX" #Telegram Secret Code
URL="https://api.telegram.org/bot$KEY/sendMessage"
TIMEOUT="10"
threshold="90" #Set Custom Threshold
i=2
result=df -kh /dev/sda1 |grep -v "Filesystem" | awk '{ print $5 }' | sed 's/%//g'

for percent in $result; do
if ((percent > threshold))
then
partition=df -kh | head -$i | tail -1| awk '{print $1}'
TEXT="$partition at $(hostname -f) is ${percent}% full"
curl -s --max-time $TIMEOUT -d "chatid=$USERID&disablewebpagepreview=1&text=$TEXT" $URL > /dev/null
fi
let i=$i+1
done

My manager told me to execute this without any explenation on what it does. Anyone here has a clue?

Edit: Sorry, i know it's long, but I'm kinda worried on the nature of this noscript.

Also, noscript has typos, sorry.

While (loop) with if-statement and timeout after 300 seconds

Hi,


I want to create a while (loop) with an if-statement which timesout after 300 seconds, when the neccessary value isnt provided from the service.


My attempt:

# API Request (GET) - Status
API_STATUS=`curl .....` 

# Set timeout value
TIMEOUT=0

while [[ "$API_STATUS" != "1.0" ]];
do
 # Increase timeout value by 1
 TIMEOUT=$((TIMEOUT+1))
 
 if [[ TIMEOUT != "60" ]]
  then
   # Wait 5 seconds
   sleep 5
   API_STATUS=`curl .....`
 
 elif [[ TIMEOUT == "60" ]]
  then 
   echo "$TIMESTAMP Not reachable." >> $LOG
   exit
 fi
done

Note:
Im executing a curl command to get a value from the backend service. If "1.0" then stop while-loop, if the service isnt reachable for example "120 seconds" wait and then proceed.

Code golf: highly minified function for injecting ANSI color in bash noscripts

I've been putting together a function for inserting ANSI color sequences in bash noscripts and trying to keep the character count down.

Here's a picture to give you an idea what I'm going for: https://i.imgur.com/6CnnGtN.png

The idea is to replace all those ubiquitous color definition blocks in the noscripts I inherit that leave the first page looking like this (clipped from a recent submission here):

#Regular Color Variables
coff='\033[0m' #No Color
black='\033[0;30m' #Black
red='\033[1;91m' #Red
green='\033[1;92m' #Green
yellow='\033[0;93m' #Yellow
blue='\033[0;94m' #Blue
purple='\033[0;95m' #Purple
cyan='\033[0;96m' #Cyan
white='\033[0;97m' #White
#BackGround Colors Variables
bblack='\03340m'
b_red='\033[41m'
b_green='\033[42m'
b_yellow='\033[43m'
b_blue='\033[44m'
b_purple='\033[95m'
b_cyan='\033[46m'
b_white='\033[47m'

I've got something that supports all 16 colors on all 16 background colors in the standard 4-bit ANSI palette, as well as bold, underline, and "terminal default" codes (`\e[39m`, `\e[49m`).

clr() {
local in="$*" fgb=30 bgb=40 colors="krgybmcw =" fg bg cs
[[ "$in" ] || { printf "%b" "\e0m"; return; } # reset
[[ "$in" == *-* ] && cs=";22;24"; # normal
[ "$in" == *+* ] && cs=";1"; # bold
[ "$in" == *_* ] && cs+=";4"; # underline
in=${in//-_+ /}
[ "${in,,}" =~ ^[.=rgbcmykw{0,2}$ ]] || return 1
fg=${in:0:1}; [ "$fg" ] || fg=.; bg=${in:1:1}; bg=${bg#.}
[ "$fg" =~ [A-Z ]] && fgb=90
[ "$bg" =~ [A-Z ]] && bgb=100
[ "$fg" == "." ] || { i=${colors%%"${fg,,}"}; cs+=";$((${#i}+fgb))"; }
[[ "$bg" ]] && { i=${colors%%"${bg,,}"}; cs+=";$((${#i}+bgb))"; }
printf "%b" "\e${cs#;}m"
}

I'm trying to keep it mostly minified so it's a tricky read. The less obvious abbreviations are `in`: input arguments, `cs`: control sequence, `fgb`/`bgb`: foreground/background brightness.

`shellcheck --shell=bash clr.sh` surprisingly had no complaints when I fed it this snippet, I was expecting to be flooded with complaints (so many unquoted expansions and assignments!) so I'm not even sure I'm using it right.

The parameters it accepts:

Parameter | Result
---|---
no arguments | Reset to default formatting
r,g,b,c,m,y,k,w | Red, green, blue, cyan, magenta, yellow, black, white
R,G,B,C,M,Y,K,W | Bright versions of same colors
+ | bold
_ | underline
- | strip formatting (bold/underline)
= | terminal default background/foreground
. | placeholder to separate foreground from background when changing background only

It doesn't care about the order of parameters or the spacing, except that the background color must be preceded by a foreground color (hence the no-op `.` placeholder for leaving foreground alone).

I'm trying to make it so that it outputs the minimal escape sequence for the desired formatting: e.g. no `0;` or `1;` when changing only the color. What I most dissatisfied with so far is having to use `22;24` to strip the bold/underline formatting, but `0;` strips the colors along with the formatting (breaking the "Blue bold not bold" example in the screenshot) and I don't want to make the function have to track any state to know whether it's underlining or bold that needs to be cancelled out.

Any tips? Especially ones that reduce the character count!

aliases to save current dir in one terminal and move to it in a different terminal

I often open a new terminal windows to work in the same directory as my current terminal window and I find it annoying to have to manually cd to it, specially if current directory path is long. There is probably a better way but here is what I came up with:

alias sf='pwd > ~/.folder'

alias lf='cd "$(cat ~/.folder)"'

sf is for save folder, lf for load folder.

I literally just came up with that so I haven't really used it for real beyond testing.

Read contents of file and run a command

My scenario:

cat filesystems.txt
#path;major;minor;average
/var;10;10;10
/opt;10;10;10

Then, my bash must read this file (filesystems.txt) and for each line of this file (except first line), do "df -h" for each item.

My goal is to have this:

df -h /var
df -h /opt

having trouble checking if a drive is mounted!

Greetings everyone,

&#x200B;

I'm making a little wrapper for pmount to automate the mounting/dismounting of hotplugged LUKS USB devices. I'll post the noscript below.

https://pastebin.com/Tr9ZUEJe

I'm having trouble in particular with the "scan" function. I'm trying to get it to display eligable devices ONLY if they are not already currently mounted. I'm not sure how to do this. Currently, it displays (correctly) all devices which 1.) have a UUID and 2.) have an associated .key file in the $SECRETSDIR/luks folder. I'd like this output to exclude whatever is included in the "currentlymounted" array.

&#x200B;

I'd really value any input about how to accomplish this, thanks in advance!

Emulate "Copy Link To Clipboard" By Copying Text Wrapper - How To?

Is it possible to do the copying in bash by emulating "copy link to clipboard" when the text wrapper is highlighted? Projecting this onto Markdown format of URL it would look like highlighting the [reddit!] segment of [reddit](https://reddit.com) with (https://reddit.com) going to the clipboard. Refer to the linked image for the visual example.

My VOIP phone service provides an API to send SMS .. is this how its done using curl

API is

https://www.thevoipcompany.com/send-sms?username=username&password=password&to=destination&subnoscriptionId=subnoscription ID&text=message

My understanding curl could do this with something like this ... correct?

>curl -X POST -d 'username=username&password=password&to=destination&subnoscriptionId=subnoscription id&text=message' https://www.mynetfone.com.au/send-sms

If correct it would be simple to put it into a bash wrapper.

Bash continuous parallelization

I work with academic research, specifically with simulations. The important feature of these simulations in the context of the problem is that some of them take longer than others.

I want to run let's say 1000 simulations, each in a single thread of the processador. If my machine has 6 threads i can do several batches of 6 + one batch of the remaining.

Using something like:

./run.out 1 & ./run.out 2 & ./run.out 3 & ./run.out 4 & ./run.out 5 & ./run.out 6 & wait
./run.out 7 & ./run.out 8 & ./run.out 9 & ./run.out 9 & ./run.out 10 & ./run.out 11 & wait

And that's definetly runs faster than doing one by one, sequentially. But if i have at least process that takes a lot longer than the others, i'm losing precious time.

The final question is: Is there a simple way that can i set a fixed number of processes to be running at the same time, and as soon as one is finishes another one takes it place, that way i'm not bottlenecked by a single slower program.

I will greatly apreciate the help, since solving this would greatly improve my reseach.
