Commands¶
This is an ongoing list of commands that I’m probably going to use a lot, as an overview for easy reference.
GIT COMMANDS¶
| Command | Description | Example |
|---|---|---|
| cd | Change directory | cd C:\Users\mvoss\Pictures\temp\ |
| pwd | Get current directory | |
| ls | List all files and folders in current directory | |
| copy, cp | Copies an item from one location to another | cp .jpg -Destination “~/Documents\Gitlab\fabacademy\michelle-vossen\assets\images\weeks\week1” |
| mkdir | Make a new directory | mkdir week2 |
| git reset –hard HEAD~ | if you pushed to many bits | goes back one command/push |
IMGMAGICK¶
| What it does | Command | extra |
|---|---|---|
| adjust extension | magick convert img.jpg img.png | |
| resize | magick mogrify -resize “800>” .jpg | |
| quality | magick mogrify -quality 75% .jpg | |
| convert all images from one extension to another (jpg to png) | magick mogrify -format jpg .png |
FFMPEG¶
| What it does | Command | extra |
|---|---|---|
| (Pieter’s secret code) | compress .jpg .jpeg | |
| (Pieter’s secret code) | compress *.mov | |
| scale and compress | ffmpeg -i input.mp4 -vcodec libx264 -b:v 500k -vf scale=-2:500 -an output.mp4 | |
| rotate | ffmpeg -i 2.mp4 -vf “transpose=1” 2.1.mp4 ffmpeg -i 2.mp4 -vf transpose=2 2.1.mp4 | 0 = 90° counterclockwise and vertical flip (default), 1 = 90° clockwise, 2 = 90° counterclockwise, 3 = 90° clockwise and vertical flip |
| Convert mov to mp4 | ffmpeg -i input.mov -q:v 0 output.mp4 | |
| Compress mp4 (you can change the 500k to another number and the scale as well to lower or increase the size) | ffmpeg -i input.mp4 -vcodec libx264 -b:v 500k -vf scale=-2:500 -an output.mp4 | |
| Speed up mp4 (lower number is faster; it drops frames so that’s good for compression) | ffmpeg -i input.mp4 -filter:v “setpts=0.06*PTS” output.mp4 | |
| Rotate video clockwise | ffmpeg -i in.mov -vf “transpose=1” out.mov | |
| Powershell command for batch ffmpeg Get-ChildItem *.mp4 -recurse | % { ffmpeg -i $.FullName -vcodec libx264 -b:v 500k -vf scale=-2:500 -an (“C:\Users\mvoss\Pictures\temp\batch” + “" +$.Name) } |

scrollable text blocks¶
# pretend that we have a lot of code in this chunk
if (1 + 1 == 2) {
# of course that is true
print(mtcars)
# we just printed a lengthy data set
}
What I learned and how I should proceed.¶
I like to make stuff. I’m inpatient, don’t have a lot of knowledge about coding and have a very broad interest in what I like to create. With fab acadamy I learned a lot of different things. You don’t learn anything that good that you’ll be a proffesional within that segment.
I should make a plan. How I can make something with the skills and abelities that I have now.
But also make a plan in what I want to learn. In what subject I should get better in. What is really usefull for me?
