## git clean up

```sh
# Delete untracked
git clean -fdx

git gc
```

## Delete `.DS_Store`

With [find](https://stackoverflow.com/q/30483670):

```sh
find . -name ".DS_Store" -print -type f -delete
```

With [fd](https://github.com/sharkdp/fd):

```sh
fd -H '^\.DS_Store$' -tf -X rm
```

## [sd](https://github.com/chmln/sd)

Remove proto options:

```sh
sd -F 'import "validate/validate.proto";' '' api/raw/*.proto
sd -F 'import "marshal-zap.proto";' '' api/raw/*.proto
sd -f s '\s\[.*?];' ';' api/raw/*.proto
```

## [fdupes](https://github.com/adrianlopezroche/fdupes)

Remove duplicated files:

```sh
fdupes -rdN .
```

## [rsync](https://github.com/WayneD/rsync)

```sh
# Result is dst/src
rsync -avzP src dst

# Result is dst/* with * is from src
rsync -avzP src/ dst
```

Commonly flags:

- `-v`: verbose
- `-z`: compress
- `-P`: enable both `--partial`, `--progress` to easily resume after interrupt
- `-n`: dry run

Be careful flags (need dry run if not sure):

- `-u`: skip if files in **dst** is already newer than in **src**, if you want
  to sync both ways
- `--delete`: delete files in **dst** if not exist in **src**, useful to sync
  dst with src

## [ffmpeg](https://github.com/FFmpeg/FFmpeg)

```sh
# -crf: quality, 0 is lossless, more is lower quality
# -an: no audio 
# -c:a aac -b:a 128k: audio codec and bitrate
ffmpeg -i input -c:v libx265 -crf 26 -preset fast -an output.mp4
```

## [libvips](https://github.com/libvips/libvips)

Convert:

```sh
# Add --vips-progress to show progress
vips jxlsave filename.jpg filename.jxl --keep=none
vips jpegsave filename.png filename.jpg --keep=none

# Batch convert (require fd)
fd "jpg|jpeg|png|webp|gif" --exec vips jxlsave {} {.}.jxl --keep=none
fd "jpg|jpeg|png|webp|gif" --exec-batch rm

fd "png|webp|gif" --exec vips jpegsave {} {.}.jpg --keep=none
fd "png|webp|gif" --exec-batch rm

# Rotate
vips rot filename.jxl new_filename.jxl d90
```

## [yt-dlp](https://github.com/yt-dlp/yt-dlp)

Download:

```sh
yt-dlp -f - "https://www.youtube.com/watch?v=video_id"
```

## [F2](https://github.com/ayoisaiah/f2)

Rename:

```sh
# If dry run, remove --exec
f2 --replace "{mtime.YYYY}{mtime.MM}{mtime.DD}_{mtime.H}{mtime.mm}{mtime.ss}_{hash.md5}{ext}" --exec

# Include ImageSize (require exiftool)
f2 --replace "{mtime.YYYY}{mtime.MM}{mtime.DD}_{mtime.H}{mtime.mm}{mtime.ss}_{xt.ImageSize}_{hash.md5}{ext}" --exec

# Not include time
f2 --exclude="\d+x\d+_[a-z\d]{32}" --sort=mtime --replace "{xt.ImageSize}_{hash.md5}{ext}" --exec

# Remove space in directory
f2 --find " " --replace "_" --string-mode --only-dir --exec
```
