Most of you will know how to navigate directories using the cd command and how to create a directory with mkdir. You will also be familiar with the mv command. The mv command is not just for moving files from one directory to another; it can also be used to rename files like this.

mv oldfilename.txt newfilename.txt

In order to list files and directories in the current folder you are in, you may use the ls command.

You can also list files and folders not in your current working directory by providing the directory path with commands like this.

ls /home/John
# to list with more details of files
ls -l /home/John
# to list all files, including hidden files
ls -la /home/John

If you look up the ls command using man ls, you will see that you can pass a lot of options. One of the useful ones is the -t option to sort the files in ascending order of time. For example, if you want to see the latest modified file at the top of the list, use the command below.

ls -t

The ls command sometimes lists a long list of files and directories, but what if you want to filter out files based on the name, time, or some other criteria ? To search through files, one can use the find command.

# finds files in the specified folder with extension .txt and which are newer than the date 2025-01-01
find /home/John -type f -name *.txt -newermt 2025-01-01

There is also an option to execute commands on results using -exec.

Use man find to see the full list of options.

A quick way to find the path of a file or directory is by using the locate command.

locate *.txt

Exploring the manual pages with man can reveal additional options for each command. Familiarizing these tools will enable you to navigate your operating system effectively.#linux #shell #bash #htb #software #coding #development #engineering #inclusive #community

OMG. In 2022, the FBI reportedly told Texas Highway Patrol to release Kilmar Abrego Garcia after he was allegedly transporting someone on the terrorist watchlist during a traffic stop.

Kilmar was reportedly transporting 7 unknown individuals from Texas to Maryland without a valid driver's license, which is a Class B misdemeanor.

This is the "Maryland Man" the Democrats defend.

🧠 The Problem


When working on multiple local branches (say for different client tasks, features, or experiments), you often:

  • Switch to a branch using git checkout
  • Pull the latest changes using git pull
  • Repeat this for every other branch

That’s fine for 2-3 branches. But what if you have 10, 20, or even 30?

“There has to be a better way.”


Spoiler: There is. ✅

🛠️ The Goal


We want to pull the latest changes from the remote for every local branch without manually checking each one out.

Let’s automate that!

🚀 Step-by-Step Solution


Here’s how to pull updates for all branches at once:

✅ Step 1: List All Local Branches


git branch

This gives you a list like:

main
* feature/login
bugfix/footer
refactor/api

Great — but we want to loop through these branches.

🧪 Step 2: Loop Through Branches and Pull


Here’s a handy Bash script that does the job:

#!/bin/bash

current_branch=$(git rev-parse --abbrev-ref HEAD)

for branch in $(git for-each-ref --format='%(refname:short)' refs/heads/); do
echo "🔄 Checking out $branch..."
git checkout "$branch" > /dev/null 2>&1

echo "⬇️ Pulling latest changes for $branch..."
git pull --rebase

echo "✅ Done with $branch"
echo "-------------------------"
done

# Switch back to original branch
git checkout "$current_branch" > /dev/null 2>&1
echo "🚀 All done! Back on $current_branch"


Save this script as git-pull-all.sh and make it executable:


chmod +x git-pull-all.sh

Run it with:

./git-pull-all.sh

🧠 A Few Notes


  • The script uses --rebase instead of a plain pull to keep history clean. You can remove it if you prefer merge commits.
  • Works best if all branches are tracking remote ones (e.g. origin/main, origin/feature/login etc.).
  • If you use authentication (like SSH keys or PATs), make sure you're authenticated before running the script.
