Some useful Bash commands


# Batch download
youtube-dl -i -F -a ~/Desktop/list.txt # Get the format
youtube-dl -i -f <format> -a ~/Desktop/list.txt # Use the format

# Automagically download the desired resolution
youtube-dl -i -f "bestvideo[height<=720]+bestaudio/best[height<=720]" -a ~/Desktop/list.txt

## Avoid throttling
youtube-dl -i --external-downloader aria2c --external-downloader aria2c --external-downloader-args "-j 8 -s 8 -x 8 -k 5M" -f mp4-240p -a ~/Desktop/list.txt
youtube-dl -f 18 -4 -i https://www.youtube.com/watch?v=uhikhkih # Use IPv4

## Rate limit
youtube-dl -i -r 120k -a ~/Desktop/list.txt


# Batch download
wget -r -H -nc -np -nH --cut-dirs=1 -e robots=off -l1 -i ~/Desktop/list.txt

# Rate limit
wget --no-check-certificate --limit-rate 60k https://trucmuche.com/truc.mp3
wget --no-check-certificate --limit-rate 20k -i ~/Desktop/list.txt # Batch download

# Recursively fetch a directory
wget -r --no-parent --reject "index.html*" -e robots=off  http://example.com/configs/.vim/

## To avoid downloading the directory structure as well
wget -r -nH -nd -np -R index.html* -e robots=off http://example.com/configs/.vim/

# Avoid the robots.txt issue
 -e robots=off  (See http://www.krazyworks.com/wget-and-user-agent-header/)

# Download one type only
 -A jpeg,jpg,bmp,gif

# Use a user-agent
 -U -U "Mozilla/5.0 (X11; U; Linux i686; pl-PL; rv: Gecko/20121223 Ubuntu/9.25 (jaunty) Firefox/3.8"

# So, get only fonts in an entire site
wget -r --no-parent --reject "index.html*" -e robots=off --limit-rate 60k -A otf,ttf,ttc,dfont 

Batch stuff

# Convert multiple video to audio
for i in *.mp4; do ffmpeg -i "$i" -vn "${i%mp4}mp3"; done
# Convert avi to mp4
for i in *.avi; do ffmpeg -i "$i" -c:a aac -b:a 128k -c:v libx264 -crf 23 -preset fast -profile:v baseline -level 3.0 -threads 2 "${i%avi}mp4"; done
# Convert mkv to mp4
for i in *.mkv; do ffmpeg -i "$i" -c:a aac -b:a 128k -c:v libx264 -crf 23 -preset fast -s 720x480 -threads 2 "${i%mkv}mp4"; done
# Convert .png to .jpg
for i in *.png; do mogrify -format jpg "$i" && rm "$i"; echo "$i converted to ${i%.*}.jpg"; done
# Same, but recursive
find . -iname '*.png' | while read i; do mogrify -format jpg "$i" && rm "$i"; echo "Converted $i to ${i%.*}.jpg"; done

# Randomize name
for i in *.mp4; do mv -i "$i" "${RANDOM}.mp4"; done

# Recursive copy
find . -name "*.zip" -exec cp -t ./direction_dir {} +
find . -type f -name "*.mp3" -exec cp {} /tmp/MusicFiles \ # Alternative
# Recursive deletion
find . -name "*.*" -print0 | xargs -0 rm -rf
# Recursive md5sum
find -type f -exec md5sum "{}" + > checklist.chk

# Recursive rename with modified date
j=1; for i in `find . -type f`; do mv -- "$i" "$(date +%Y-%m-%d_%H\'%M\'%S -r $i)_$j.${i##*.}"; j=$((j + 1)); done
## Will output: 2021-02-01_15'16'06_foo.webm
## Note: use IFS=$'\n' before the loop, for find to understand space in filename (mandatory on Windows)

# Recursive move from multiple folder, renaming the files to add the folder they was in
ls . > list; while read LINE <&3; do for i in `find $LINE -name "*.svg"`;do filename=$(basename -- "$i"); cp $i "$LINE-$filename"; done; done 3< list; rm list;

# Recursive move in folders
for j in {01..31}; do for i in `find . -name "*\-$j\_*"`; do mkdir -p "$j" && cp "$i" "$j/"; done; done
## Use case: we have a bunch of files named 2021-02-01_15'16'06_bar.webm, we want them to be moved into the folder corresponding to their month (01 to 31)

Video to gif

# Simple
for i in *.mp4; do ffmpeg -i "$i" -an -s 320x240 -pix_fmt rgb24 -r 10 "${i%mp4}gif"; done
# Optimal with compression

# Recursive on the first 15 seconds with deletion of step's products
for i in `find . -name "*.webm"`;do ffmpeg -ss 0 -t 15 -i "$i" -vf fps=10,scale=320:-1:flags=lanczos,palettegen "$i.png"; ffmpeg -ss 0 -t 15 -i "$i" -i "$i.png" -filter_complex 'fps=10, scale=320:-1:flags=lanczos[x];[x][1:v]paletteuse' "${i%webm}gif"; rm "$i.png"; rm "$i";done


# Get filename and extension
filename=$(basename -- "$fullfile")
