Hello everyone!

I want to introduce my current project crazy-complete.

It is a tool that generates shell auto-completion files using a single configuration file.

Key Features

• Simple configuration: The tool uses an easy-to-use YAML format
• Multi shell support: The tool supports Bash, Fish and Zsh
• Option types: All common option types are supported: long-options (--option), short-options (-o) and old-style-options (-option)
• Argument types: Options with required arguments, with optional arguments and no arguments are supported
• Mutually exclusive options: You can define groups of options that can't be used together
• Repeatable options: You can control if an option may be repeated on commandline, or should appear only once
• Positional arguments: You can easily define arguments for your program
• Built-in completion types: The tool comes with these completions: file, directory, choices, value_list, range, signal, process, pid, command, user, group, service, variable, environment
• Custom completions: If the built-ins aren't sufficient, there is the exec command to complete stuff based of a command's output
• Conditional options/positionals: You can enable options and positionals based on conditions, like "is there an option present?" or "does an option have a specific value?"
• Subommands: You can specify arbitrary levels of subcommands
• Robust scripts: Unlike other generation tools, cracy-complete parses the whole commandline according to the specified options (instead of only looking at the last two args, for example)
• Efficient scripts: Scripts were made with efficiency in mind. You pay only for what you use.
• Well tested: There are over fifty tests per shell to ensure correct behaviour

Other Features

• argparse Support: If your program is written in Python and uses the arparse-module, there is a chance that you can generate scripts (or YAML files) from the argparse.ArgumentParsers's definitions
• Help text parser: If your program comes with a help text, there is a chance that you can generate YAML definition files by parsing it's output

If you're tired of maintaining completion scripts for different shells, crazy-complete may be for you.

Even if you decide against using generated scripts, the output of the tool may serve as an inspiration.

Let me know what you think. If you need support or have any questions or improvement-ideas, don't hesitate to ask!

And if you like the tool, please give it a star on GitHub

I dont understand why i cant change certain file permitions (i can change some but not all).
I tried running sudo but it cant find the command and i cant seem to instal sudo with "su -".
Im running "git bash" on a windows... I also have 2 users, one personal, one for coding. Might it be the user settings? If so what and how do I change it... No one in my cluster has any info, help 💀🙏

Hi, I'm just curious: what does this mean?

I know it's telling the machine to use bash, but like, why is it a "#!" for example? How/why was it decided that way?

On a road trip to Dallas, TX, we stopped at a Shell (the gas station) in Arkansas to hot to the bathroom. There was fucking BARNACLES on the SINK. BARNACLES! My hands felt dirtier after washing. Words cannot describe how infuriated I was, and still am, despite the encounter being a week ago. I needed to vent about this. This is not clickbait. This is REAL. Never going to a shell again.

Hi, new to coding just started studying shell.
Cant seem to change this files permitions, what am i doing wrong?
(i need to give g and o x permition, have already tried numeric and symbolic methods)

I need to know everything the pc is doing, for example I need to read it and be able to copy and paste the text to activate it, for example the if any app is open and anything I do on it I can see and still copy and paste to do the same, yes I know it's very weird, but if you smart guys or girls know I would love to know, sorry I didn't explain it well

shell script-1 :

#!/bin/bash

cd /(path)/DB/test

for line in $(cat ./test_list.txt); do
   ./../batch_download.sh -f ./${line} -p &
done

I closed the terminal, but the execution didn't stop. I checked, it is truly downloading files.

However,

shell script-2:

#!/bin/bash

cd /(path)/DB/test

./../batch_download.sh -f ./entry0.txt -p 

I cannot close the terminal.

Hi All

I have implemented a unit test for a Shell using shellspec. And I am always thrown the above error in 'before all' and 'after all' both. Even though the log contains exit code 0 which basically indicating there is no error none of my tests are executing.
I have added extra logs and also redirected the errors but still I am facing this error and am out of options. I am using the latest version of Shellspec as well.

I am mocking git commands in my test script. But it is quite necessary for my tests as well.

I even checked for the relevent OS type in the setup method

 # Determine OS type
    OS_TYPE=$(uname 2>/dev/null || echo "Unknown")

    case "$OS_TYPE" in
        Darwin|Linux)
            TMP_DIR="/tmp"
            ;;
        CYGWIN*|MINGW*|MSYS*)
            if command -v cygpath >/dev/null 2>&1; then
                TMP_DIR="$(cygpath -m "${TEMP:-/tmp}")"
            else
                echo "Error: cygpath not found" >&2
                exit 1
            fi
            ;;
        *)
            echo "Error: Unsupported OS: $OS_TYPE" >&2
            exit 1
            ;;
    esac

Any guidance is immensely appreciated.

I recently published a comment about my todo list on HN and a few people asked about it. I decided to do a quick write-up of the simple commands I put together to accomplish this in the shell (zsh in my case but it likely works in bash too).

Asking for a brother who is building tools to help other shell/Terminal layer programmers. Thank you.

No, something different than you think... xz performs up to 2% better on ARM64 than AMD64 with the same settings and I have double checked the version, it is the same! gzip on the other hand... no change at all. Also interesting, xz -1 and AMD64 is WAY faster and better than gzip except memory usage but even 100MByte are pretty tame nowadays. So basically gzip is now superfluous in ever aspect, even on my 1990 Amiga with bash and xz I can unpack those Archives, and faster than xz too. And no, I didn't benchmark the Amiga too. I only remember it from the last time I booted it up.

I think that is self-explanatory.

Hello, I am new to scripting and trying to make a script that will make it easier to use yuescript to code with the love2d framework. I am currently facing an issue with the zip command.

yue -t lua src
rm game.love
zip -r game.love lua
love game.love

The probem is that the root is lua directory and not main.lua, using lua/* doesn't seem to work, the rest works as intended

Here is how to customize your boring default terminal to boost your productivity. Discover useful terminal commands for navigation and shortcuts to enhance your terminal experience.

etcsh is an enhanced version of the original tcsh, which is a version of the original Berkeley C shell implementing file name completion and command line editing.

etcsh features the following enhancements and fixes over the original tcsh.

• Function declarations;

• variable assignment from pipes and redirections;

• comments on interactive sessions;

• tell whether stdin is empty or not;

• variable expansion on expressions corrected;

• piped built-ins are forked;

• missing test built-in implemented;

• read-write variable flag;

• exit shall cancel lists.

More is to come. Feedbacks and contributions are much appreciated.

I have written a shell that uses the Python language as the scripting language: it's a shell environment that combines the expressiveness of shell pipelines with the power of python iterators.

It can be used in two major ways:

• As an interactive shell replacing e.g. bash
• As an ordinary python module replacing e.g. subprocess.Popen

Obligatory example:

140:/home/redhog/Projects/beta/pieshell >>> for x in ls(-a):
...   if x.endswith('.py'):
...      print x
... 
setup.py

Hi all,

after using fish for about 5 years, I have tried the rc shell. I would like to share my experience so far: rc shell instead of bash or fish. If there are any other rc users in this sub, maybe you can help me with some of the open points (like how to copy the current command buffer or better integration of fzf).

VAR1=123 VAR2=456 VAR3=789

VARIABLES="VAR1 VAR2 VAR3"

for i in $VARIABLES do echo "$i = $$i #something like this

done

Expected output: VAR1 = 123

Hi
I'm sure some of you have ever wished to be able to just easily sync changes from one windows terminal instance to another one, for example a secondary laptop or a work device.

If so, consider adding a thumbs-up or your comment to this feature request, thanks!

hello

https://github.com/MonkeyWearingAFezWithAMop/UnityBuild-Upload/blob/main/install_butler.sh

I was trying to work out how to install butler for itch.io

https://itch.io/docs/butler/installing.html

but got stuck trying to "add butler to path" (whatever that means)

I asked chatgpt to write a script to do this and it made this and it seemed to work...

can anyone explain what "adding to path" means?

and what exactly was I supposed to do once I got to this step in the instructions

I was using a macbook pro if that makes any difference to you explanation?

thanks

I am trying to process multiple files present in a folder. My requirement is to process ALL the files but at max 15 in parallel. I wrote the below script to achieve the same.

​

However, this isn't working as expected. This script is processing all the files in the firs iteration (i.e. 15 in this case) but once the first 15 are done, it's processing alternate files. Thus if a folder has say 27 files, it's processing all the first 15 and then 6 of the remaining 12.

​

What am I doing wrong and how can I correct it?

#!/bin/bash

# Path to the folder containing the files
INPUT_FILES_FOLDER="/mnt/data/INPUT"
OUTPUT_FILES_FOLDER="/mnt/data/OUTPUT"

# Path to the Docker image
DOCKER_IMAGE="your_docker_image"

# Number of parallel instances of Docker to run
MAX_PARALLEL=15

# Counter for the number of parallel instances
CURRENT_PARALLEL=0

# Function to process files
process_files() {
    for file in "$INPUT_FILES_FOLDER"/*; do
	input_file=`basename $file` 
	output_file="PROCESSED_${input_file}"

	input_folder_file="/data/INPUT/${input_file}"
	output_folder_file="/data/OUTPUT/${output_file}"

	echo "Input File: $input_file"
	echo "Output File: $output_file"

	echo "Input Folder + File: $input_folder_file"
	echo "Output Folder + File: $output_folder_file"


        # Check if the current number of parallel instances is less than the maximum allowed
        if [ "$CURRENT_PARALLEL" -lt "$MAX_PARALLEL" ]; then
            # Increment the counter for the number of parallel instances
            ((CURRENT_PARALLEL++))
            
            # Run Docker container in the background, passing the file as input
	    # docker run hello-world
	    docker run --rm -v /mnt/data/:/data my-docker-image:v5.1.0 -i $input_folder_file -o $output_folder_file &
            
            # Print a message indicating the file is being processed
            # echo "Processing $file"
        else
            # If the maximum number of parallel instances is reached, wait for one to finish
            wait -n && ((CURRENT_PARALLEL--))
        fi
    done
    
    # Wait for all remaining Docker instances to finish
    wait
}

# Call the function to process files
process_files
