Notes on using Docker in practice.

Override entry point in run command

Add the following option: --entrypoint "/bin/bash"

Access running container

Copy Text to the Linux / X Clipboard

from subprocess import Popen, PIPE

def copy_clipboard(msg):
    ''' Copy `msg` to the clipboard '''
    with Popen(['xclip','-selection', 'clipboard'], stdin=PIPE) as pipe:
        pipe.communicate(input=msg.encode('utf-8'))

Rename PDFs by Title.md

Rename a directory of PDF files by their title as reported by pdfinfo.

Bash script

#!/bin/bash

mkdir -p "renamed"

source activate myenv
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"

Notes

Make sure you install jupyter in the environment to be added.

This is a super simple gist, but I never can remember it.

#!/bin/bash	

for file in *.jpg
do
    echo "converting $file"
    convert "$file" "$(basename "$file" .jpg).dds"
done

Sorted list of the total size of all children under the current directory

Linux

alias ds='du -sh * | sort -h'

You must first (IIRC) install GNU gsort (via homebrew).

Mac-style `open` command on Linux

alias open=xdg-open

Mac-style CLI copy / paste on Linux

alias pbcopy='xclip -selection clipboard'
alias pbpaste='xclip -selection clipboard -o'

Example usage

Pipe clipboard contents to do_something.bash and copy results back to the clipboard.
