Motivation

I am noticing physical strain on my right pinky finger. Navigating lines of code is not ergonomic. I am discovering ways to distribute the amount of work done by my pinky to the left hand.

Hence, I rely on shortcuts to accomplish efficiency and reduce pain. I have listed both default and customized shortcuts that I am trying to master and become embedded in my subconscious brain.

VS Code customization

One may add customized keyboard shortcuts via cmd-K.

Terminal

Zip

zip combines files with compression. Use zip for cross-platform compatibility.

`zipinfo directory.zip`
`zip -r directory.zip directory`

Tar

tar combines files without compression. tar is primarily used in Unix/Linux environments. It provides incremental backups.

To tar:

$ tar -cvf born-only.tar /jet/home/sleem/projects/20240218-AlOOH-BORN
$ tar -cvf born-only.tar

To untar:

$ tar -xvf born-only.tar

For -cvf -c instructs tar to create a new archive, -v enables the verbose mode which displays the progress in the terminal, showing the files being archived, and -f indicates the filename of the archive, which directly follows this option.

-xvf extracts files from a tar archive using -x instead of -c.

HPC

The following may not be useful for those who are not using the following HPC platform.

Bridges

To make an interative session:

interact -n 64 -t 8:00:00

Module

module avail mkl

Unix-like OS commands

####

which twine

Get folders size

du -h --max-depth=1 | sort -rh

The command du -h --max-depth=1 | sort -rh is used in Unix-like operating systems to list directories and their sizes within the current directory.

  • du: dist usage
  • -h: human redable
  • --max-depth=1: report one level below the current directory
  • sort: sorts lines of tet
  • -r: reverse order: largest items first
  • -h: Sorts numbers with size suffixes (K, M, G)

Find file location

find /jet/home/sleem -name Snakefile

Use Grep to list files

To list files by searching for text patterns using regular expressions:

ls /opt/packages/oneapi/v2023.2.0/mkl/2023.2.0/lib/intel64 | grep libmkl_intel_lp64
libmkl_intel_lp64.a
libmkl_intel_lp64.so
libmkl_intel_lp64.so.2
