Netizen Tercerahkan #1
One liner shell [script] of the day : #53 (audio track from one video, video track from another)
ffmpeg -i goodvideo.mp4 -i goodaudio.mp4 -map 0:v:0 -map 1:a:0 -c:v copy -c:a aac -strict experimental goodall.mp4
One liner shell [script] of the day : #52 (overlay separuh di video)
ffmpeg -i input.mp4 -loop 1 -i overlay_top.png -filter_complex "\
[0:v]trim=0:33,setpts=PTS-STARTPTS[v0]; \
[0:v]trim=33:1180,setpts=PTS-STARTPTS[v1]; \
[v0][1:v]overlay=0:0:shortest=1[ovl]; \
[ovl][v1]concat=n=2:v=1:a=0[outv]" -map "[outv]" -c:v libx264 -crf 18 -preset fast output.mp4
Dari detik 0 sampai 33, taruh overlay_top di separuh atas video, kemudian sisanya lempeng-lempeng saja. Ceritanya mau ngedit judul presentasi.
One liner shell [script] of the day : #51 (ngambil gambar asli dari PDF)
#!/usr/bin/bash
# usage ./pdfimages.sh output-dir pdf-file
mkdir -p "$1" && pdfimages -p -j "$2" "$1/tmp" && i=0; for img in "$1"/tmp-*; do [[ -f "$img" ]] || continue; p=$(basename "$img" | cut -d'-' -f2 | sed 's/^0*//'); printf -v pp "%03d" "$p"; printf -v nn "%03d" "$((i++))"; convert "$img" "$1/$pp-$nn.jpg"; done

Machine learning tanpa pattern recognition itu quacky obfuscation.

[not quite one liner] shell of the day : #51 (folder album foto kronologis)
Ceritanya ada banyak foto jepretan berbagai kamera dari folder hasil recovery, sehingga tidak ada filename atau struktur direktori yang bisa menjelaskan. Biar lebih rapi dan praktis, kita taruh saja dalam direktori sesuai bulan foto tersebut terjepret (menurut EXIF).
for file in `find . -iname *.jpg`; do
Extract the date from EXIF metadata (DateTimeOriginal)
exif_date=$(exiftool -DateTimeOriginal -d "%Y%m" "$file" 2>/dev/null | awk -F': ' '{print $2}')
# Check if the file has an EXIF date
if [[ -n "$exif_date" ]]; then
# Create the directory if it doesn't exist
target_dir="$exif_date"
mkdir -p "$target_dir"
# Move the file to the target directory
mv -vf "$file" "$target_dir/"
fi
done
Pastikan kamu punya exiftool.
