Copy standard output in Linux terminal to Windows clipboard (example until pipe):
cat blah.txt | clip.exe
wslpath 'c:\users\rest\of\path'
returns '/mnt/c/users/rest/of/path' on Ubuntu. Works with drag-and-drop from Windows Explorer (which drops the Dos path).
To get Windows path to current Unix directory: WARNING: DO NOT ALTER UNIX FILES IN WINDOWS!!!
pwd | xargs -I % wslpath -w '%'
Usage:
- -a force result to absolute path format
- -u translate from a Windows path to a WSL path (default)
- -w translate from a WSL path to a Windows path
- -m translate from a WSL path to a Windows path, with '/' instead of ''

# removes ^M end of line characters (carriage return/line feed thing) from Dos files for Unix compatability
tr -d '\r' < "$1" > "${1%.*}.UX.${1##*.}"Simply execute pandoc.exe --help to test if works; seems to work on 64bit version. Note: ~ doesn't work like in unix, use tab to autocomplete and write full path.
pandoc.exe C:\Users\yegli\Documents\MakeNotes.md -f gfm -t latex -s -o C:\Users\yegli\Documents\test3.tex
- gfm = github flavoured markdown
- latex probably needs a lot more options to work properly; does not do well with codeblocks
- html export works okay
Mashed a key and switched the keyboard layout to Canadian French while inside a MobaXterm X11 windowÉ Fix it by running this command in terminal:
setxkbmap -layout us
This causes system date to diverge from reality and may cause problems. To fix:
install ntpdate with sudo apt install ntpdate
then run:
sudo ntpdate pool.ntp.org
This connects to a cluster of timeservers: pool.ntp.org: the internet cluster of ntp servers and retrieves correct time. Apparently there are better ways to do this but should not be necessary for standard bioinformatics applications, probably. (from: microsoft/WSL#4245 )
Some networks can block ntp update, a workaround involves syncing time over http:
sudo apt-get install htpdate
sudo htpdate -a google.com
time - ntpdate: no server suitable for synchronization found - Ask Ubuntu
The WSL2 clock lag issue breaks apt updates. If sudo apt update produces errors like:
bionic-security/InRelease is not valid yet (invalid for another 4h 32min 36s)
This indicates WSL2 time does not match Windows system time, nor server time. To get the system time from the Windows machine, run:
sudo hwclock --hctosys
Then re-run sudo apt update and proceed from there.
The above failure will lead to inability to install any packages, appearing as server connection errors.
sudo apt update error: "Release file is not yet valid" - Ask Ubuntu
If in the process of switching from archive.ubuntu.com to old-releases.ubuntu.com in /etc/apt/sources.list -- from assuming the package issue came from broken repository paths and an outdated OS -- you break apt, it can be reconfigured by replacing the above file with the contents here: How to configure apt-get after you had ubuntu installed. · GitHub

tl;dr check the clock first if on WSL2. Don't go down the rabbitholes I did. There's nothing good there.
Note: update apt-get if you haven't in a while, if the usual repo sites return 404'd
Sometimes you need the absolute path for a font, here's a way to get it:
#!/usr/bin/env python3
# Imports
import os
import re
import shutil
from glob import glob
from matplotlib import matplotlib_fname
from matplotlib import get_cachedir
# Copy files over
dir_source = '<your-font-directory-here>' # on WSL: /mnt/c/Windows/Fonts/
dir_data = os.path.dirname(matplotlib_fname())
dir_dest = os.path.join(dir_data, 'fonts', 'ttf')
print(f'Transfering .ttf and .otf files from {dir_source} to {dir_dest}.')
for file in glob(os.path.join(dir_source, '*.[ot]tf')):
if not os.path.exists(os.path.join(dir_dest, os.path.basename(file))):
print(f'Adding font "{os.path.basename(file)}".')
shutil.copy(file, dir_dest)
# Delete cache
dir_cache = get_cachedir()
for file in glob(os.path.join(dir_cache, '*.cache')) + glob(os.path.join(dir_cache, 'font*')):
if not os.path.isdir(file): # don't dump the tex.cache folder... because dunno why
os.remove(file)
print(f'Deleted font cache {file}.')To get font path for a PyQt text instance:
from PyQt5 import QtGui
from matplotlib import font_manager
x = QtGui.QFont().family() # will be a string
font_manager.find_font(x) Something similar happened after running dpkg I think, either that or mamba. Anyway, to clear up memory if vmmem is eating up the bulk of it in task manager:
in PowerShell (as admin), run Restart-Service LxssManager
Note: this will kill all WSL2 processes
