About

When we download a release from any project on GitHub we need to verify the integrity of the downloaded artifact. That is way most project come with their SHA256 checksums file, that we can download and compare with the calculated SHA256 checksum of the downloaded artifact.

For example, to download the latest version (3.1.1) of openssl for a Linux 64-bit system and verify its integrity with the SHA256 checksum:

$ curl -OL "https://github.com/openssl/openssl/releases/download/openssl-3.1.1/openssl-3.1.1.tar.gz"
$ curl -OL "https://github.com/openssl/openssl/releases/download/openssl-3.1.1/openssl-3.1.1.tar.gz.sha256"
$ echo "$(cat openssl-3.1.1.tar.gz.sha256)" "openssl-3.1.1.tar.gz" | sha256sum --check

            (",") echo "$char"; printf "%${indent}s";;
            (*) printf "%s" "$char";;

Fix sasquatch installation for binwalk

For anynone that is running the latest version of binwalk (Binwalk v2.3.3) and when trying to extract squshfs filesystems, gets the following error:

WARNING: Extractor.execute failed to run external extractor 'sasquatch -p 1 -le -d 'squashfs-root' '%e'': [Errno 2] No such file or directory: 'sasquatch', 'sasquatch -p 1 -le -d 'squashfs-root' '%e'' might not be installed correctly

it might have to do that the sasquatch project is missing or not working correctly.

Install sasquatch

About

Download the latest release of a project for your architecture from any project on GitHub. The only thing you need to know is the project's name, owner and the naming convention for the releases.

For example, to download the latest version of chroma for a Linux 64-bit system:

$ TAG=$(curl -sS https://api.github.com/repos/alecthomas/chroma/releases/latest | jq -r '.tag_name')
$ curl -OL "https://github.com/alecthomas/chroma/releases/download/${TAG}/chroma-${TAG:1}-linux-amd64.tar.gz"

Another example, to download the latest version of protobuf for a Windows 64-bit system:

thanoskoutr

#!/usr/bin/python3

a = []

for i in range(0,100):
	a.append(i)

for i in a:
	print(i)

thanoskoutr

const a = [];

for (let i=0; i < 100; i++) {
  a.push(i);
}

a.forEach(i => console.log(i))

thanoskoutr

#include <stdio.h>

int main ()
{
    int a[100];
    for (int i = 0; i < 100; i++) {
      a[i] = i;
    }
    for (int i = 0; i < 100; i++) {
      printf("%d ", a[i]);
