BASH NOTES

USED ON EHD EXD EDH to rename files by date

for d in *; do

LIST ALL DIRECTORIES BY CREATION DATE

ls -lct

LIST ALL FILES CREATED TODAY

find . -mtime -1 -type f -print

EXPORT TO A CSV

find . -mtime -1 -type f -print > opened-today.csv

LIST ALL PROCESSES

 ps ax
 ps ax -o pid,ni,command

FLATTEN

find dir1 -type f -exec mv {} dir1 \;
find dir1 -depth -exec rmdir {} \;

LIST DIRECTORIES (and list while removing slash)

ls -d */
ls -d */ | cut -f1 -d'/'

FIND DIFFERENCE IN TWO FOLDERS/DIRECTORIES

diff -rq dir1 dir2 | grep 'Only in dir2/'

GET FILENAME WITHOUT EXTENSION

filename=$(basename -- "$fullfile")
extension="${filename##*.}"
filename="${filename%.*}"

Convert notebook to html if not already html

IN ENGLISH: For all python files, check if an html already exists. If not, make one.

ADDING TO AN ARRAY

args=()
for i in *.html; do
    args+=("$i")
done
echo "${args[@]}"

for i in *.ipynb; do
  if [[ ! " ${args[@]} " =~ " ${i%.*}.html " ]]; then
    jupyter nbconvert --to html $i
    echo "$i"
  fi
done

CHECK IF FILE EXISTS IN FOLDER:

for i in *.ipynb; do
  find "${i%.*}.html";
done

OLD, NOT WORKING LIKE I WANTED LOL

for d in *; do
  if [[ $d == *.ipynb ]] ; then
      if [[ $d != *.html ]] ; then
          echo "$d"
          jupyter nbconvert --to html $d
      fi
    fi
done

for d in *; do
    if [[ $d != *.html ]] ; then
        echo "$d"
        jupyter nbconvert --to html $d
    fi
done

Fixing File Permissions (especially on jupyter notebook)

/usr/local/share/jupyter/nbconvert/templates sudo chmod a+rwx html/

help here

CONVERT ONE FILE

jupyter nbconvert –to html notebook.ipynb

(IF YOU WANT IT TO EXECUTE)

jupyter nbconvert –execute –to html notebook.ipynb

ADD DATE TO FILE NAME:

for d in ; do newdate=$(stat -f %SB -t %Y%m%d “$d”) filename=${newdate}${d##_/} echo “$filename” cp $d “$filename” done

CONVERT ALL .ipynb FILES TO .html

for d in *.ipynb ; do jupyter nbconvert –to html $d done
