GNU\Linux

I currently run Debian Testing and I use VIM. None of this matters of course, I just think it’s cool.

Convert a bunch of GoPro images for a time-laps

ffmpeg -r 30 -y -pattern_type glob -i '*.JPG' -vf "crop=h=2250" -c:v libx264 -crf 20 -s 1280x720 outfile.avi'

Screencasting with ffmpeg

ffmpeg -f x11grab -s 1366x768 -i :0.0 -c:v libx264 -qp 0 out.mkv

Convert a 16bit tiff thermal image to something more viewable

gdal_translate infile.tiff outfile.tiff -b 1 -scale 6880 7641 0 65535

Convert a Panasonic Raw (from MAPIR Survey2 Camera) to a usable jpg and transfer exif info from the correpsonding JPG (weird setup, I know)

darktable-cli infile.RAW outfile.jpg && exiftool -tagsfromfile infile.JPG -x Orientation outfile.jpg

Split Netcdf files by level

cdo splitlevel,500 infile_with_various_levels.nc outfile_with_level_500.nc

Remove a page in a PDF file (remove first page of a 7 page pdf file)

pdftk infile.pdf cat 2-7 output outfile.pdf

Compress a pdf file

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/printer -dNOPAUSE -dBATCH -sOutputFile=outfile.pdf infile.pdf

Merge a pdf file - I had two LaTeX documents with different classes but with the same page setup, this was the easiest way.

pdfunite infile_1.pdf infile_2.pdf merged_output.pdf

LaTeX needs to be compiled twice, instead of running commands over and over do:

for i in `seq 2`; do makeglossaries texfile && bibtex texfile && lualatex texfile.tex ; done

To make LaTex compiling even more simple, use zsh and do:

repeat 2 { makeglossaries texfile && bibtex texfile && lualatex texfile.tex }

Update all git repositories in a given directory

for i in */.git; do ( echo $i; cd $i/..; git pull; ); done

Convert a multisheet spreadsheet to a csv file. UPDATE: This is not a good idea for multi-sheet spreadsheets.

xlsx2csv sheet.xlsx -d ';' --all > sheet.csv

Docx to Tex format

pandoc -f docx -t latex -o out.tex in.docx
