I often use grep in Windows and Linux to find text in files. I have noticed that grep only works on traditional text files with .txt, .c, .cpp, .list, etc extensions. It doesn’t work with Markdown and C# text files and I find this frustrating.
I have found a parallel grep program in the Microsoft Learn code samples written by David Pine that overcomes the grep limitations.
The thing that I really like about this program is that I can use regular expressions in the search text.
I am used to gaining elevated privileges in Linux by adding sudo to a command e.g.
sudo apt-get update I wanted to stay in elevated privileges so I went to login as root and realised that my normal Linux account didn’t have root privileges.
I did some searching on the Internet and found that most versions of Linux disable the root account by default.
I found that you can enable root by running the following command.
I have been using the Windows Subsystem for Linux (WSL) for a number of years and just assumed that I was using WSL 2.
A quick check told me that I was definitely using WSL 2.
Note: I am using Powershell to check the version of WSL I have installed.
wsl --status Returned.
Default Distribution: Ubuntu-20.04
Default Version: 2

I am using the bash shell in Windows WSL Linux. Currently I am using the Ubuntu 20.04, Debian and OpenSuse distributions.
The problem I have is that the default colour scheme has an ugly green background colour with blue text
This is a really disconcerting colour scheme!
I looked around for an alternative colour scheme to use and found that I could run a command to change the colours manually but each time I opened the terminal I would have to run the command again.
I am having real problems keeping my ASUS netbook running. It doesn’t have enough specs to run a lightweight version of Linux.
Increasing the size of the swapfile is supposed to improve the performance of low specced machines.
I have worked out how to change the swapfile size in the hope that it may help.
To check if you actually have a swapfile.
swapon -s This will either return nothing or detail the swapfiles statistics.
