lFor Mac keyboard keys, almost all (except the old solid and open Apple logo’s) have a Unicode code point, see for instance the modifier keys from the [WayBack] List of Mac/Apple keyboard symbols · GitHub (the “Alt” column has a solid Apple logo in the bottom right; on non-Mac systems it will look differently as it is in the Unicode private range: [WayBack] Unicode Character ” (U+F8FF): ‘<Private Use, Last>’):

These are the code points for the “Sym” column:

History repeating itself: [Archive.is] 31607 – C:\nul\nul crashes/BSOD then, now it’s this:

All versions prior to Windows 10 and Windows Server 2016 seem vulnerable.
So add $MFT to this list:
Oh BTW: history repeated itself this year too. With NUL
In short, Steven Sheldon created a rust package named nul which broke the complete package manager on Windows:
BTW: one of my gripes on learning new languages is that they come with a whole new idiom of their ecosystem: rust, cargo, crates, all sound like being a truck mechanic to me.

I wrote two tiny batch files that would dump the environment variables from the registry.
Various reasons:
- Environment variables can be stored in two contexts: System and User (SET will show them all at once and for instance combine PATH up to 1920 characters).
- Environment variables can be set to auto-expand or not, which you cannot see from a SET command (REG_EXPAND_SZ versus REG_SZ).
show-user-environment-variables.bat:
reg query "HKCU\Environment"
show-system-environment-variables.bat:
reg query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"
Filtered results:

Very interesting question and answers: windows 7 – Available memory differs by several GiB from what is installed – Super User.
Basically the missing memory can be due to:
- Windows licensing limitations
- Mapping of device memory into virtual memory space (especially on x86 systems)
This affects both server and client versions of Windows. Client versions are more restrictive because of the vast amounts of potentially faulty drivers involved.
Some links (read the full question for details):

Usually I use the old Borland grep.exe that still ships with Delphi. Too bad it is 16-bit app which does not recognise Unicode.
FindStr does. Though much slower and with limited regular expression capabilities, can do recursive searches too:
findstr /spin /c:"string to find" *.*
The /spin is a shortcut for these case insensitive command-line options (the full list of possible options is below):
/S Searches for matching files in the current directory and all
subdirectories.
/I Specifies that the search is not to be case-sensitive.
/N Prints the line number before each line that matches.
/P Skip files with non-printable characters.
Sometimes I leave out the /P to include binary files.
