20 Cool Command Line Tricks for Windows and macOS

Posted by jpluimers on 2019/11/08

After all these years in the field, I still learned new tricks from [WayBack20 Cool Command Line Tricks for Windows and macOS which I have rephrased:

Windows

1) View installed drivers: [WayBack] driverquery

2) Watch Star Wars in ASCII: [WayBacktelnet towel.blinkenlights.nl

3) Save folder trees to disk: tree (I had totally forgotten about this, probably because it leaves out a lot of directories and files)

5) Show your Wi-Fi password [WayBacknetsh wlan show profile SSID key=clear (replace SSID with your network name; use nets wlan show profile to view the network names)

7) Check your laptop’s battery health: [WayBack] powercfg /batteryreport which will be in ” and hit Enter to generate the report, then %HOMEPATH%\battery-report.html

8) View your Windows license key: wmic path softwarelicensingservice get OA3xOriginalProductKey [WayBack]

Mac OS X / macOS / however it is called now

1) Change the default screenshot type: [WayBackdefaults write com.apple.screencapture type JPG (you can also use JP2 (for JPEG2000), PDF, PNG, TIFF and others)

2) Get your Mac to speak to you: use say

3) Add a message to the login screen: sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "your new text on the logon window" [WayBack]

4) Play Tetris and other classics: start emacs, then press Esc followed by X, type in tetris, pong, snake or solitaire (to exit emacs, press CtrlX followed by CtrlC). There are [WayBack] more emacs games.

5) Get a dictionary definition: run curl dict://dict.org/d:word (where word is what you are after) which uses the [WayBack] dict protocol

6) Keep macOS awake: [WayBack] caffeinate optionally followed by a -t## parameter where ## is the number of seconds to not sleep.

7) Show hidden files: defaults write com.apple.finder AppleShowAllFiles -bool TRUE; killall Finder or use this AppleShowAllFiles script which I had forgotten about writing in the first place.

10) Add Spaces to the Dock: defaults write com.apple.dock persistent-apps -array-add ‘{”tile-type”=”spacer-tile”;}’; killall Dock running the command as many times as you want spaces. To get rid of a space you’ve added, just drag them to the Trash.

wget and curl: downloads that sometimes fail

Posted by jpluimers on 2018/10/19

For my archive somewhere between cURL 7.21.0 and 7.34.0 it does not like to be started from an RDP based tsclient share:

It fails the same way after net use B: \\tsclient\bin, so that does not matter.

The best link I could find until I got to the real problem was [WayBack] curl: (6) Could not resolve host: application – Stack Overflow which shows a different problem: properly quoting.

In addition to remote-name, you can also grab the file name from the headers using --remote-header-name, and --remote-time use the remote file time. The --location follows 302-redirects. You can see that in the example below which I build based on

[WayBack] unix – Curl to grab remote filename after following location – Stack Overflow: The remote side sends the filename using the Content-Disposition header.curl 7.21.2 or newer does this automatically if you specify –remote-header-name / -J.curl -O -J -L $url

C:\Users\jeroen\Downloads>b:\curl.7.21.0.exe --location --remote-name --remote-time --remote-header-name "https://web.archive.org/web/20180712073755if_/https://www.danielwolf.eu/?wpdmdl=1965"

Giving up.

This is not caused by the filename (Windows does not like the ? question mark in output file names, so  – like & ampersand in file URLs – you have to quote the full URL, but also provide the --restrict-file-names=windows parameter; see [WayBack] wget – I can’t download files with “?” – Super User).

https://altd.embarcadero.com/ TLS certificate does not match domain name

Posted by jpluimers on 2018/09/07

One of the domains not yet monitored at embarcaderomonitoring.wiert.me, was the altd download server for ISOs and installers on http and https level. Ultimately you want https, as most of these are about installers, so you do not want any man-in-the-middle to fiddle with them.

TLS on altd fails

Upitmerobot is not yet smart enough to check validity of TLS certificates on https connections.

Chrome, Firefox, Safari, Internet Explorer, wget, curl and ssllabs however are.

altd hides as much from itself as possible

Uptimerobot did not like monitoring the plain http://altd.embarcadero.com/ and https://altd.embarcadero.com/ URLs, because the altd is not browsable, so it tries to hide most of its structure from access. This means they both return an odd response:

Those responses are actually 404 errors (note the - minus sign after curl --trace-ascii: it sends the trace to stdout):

This is also the reason that WayBack does not want to archive that link, but it can be archived at [Archive.ishttps://altd.embarcadero.com/.

Luckily, a Google search for site:altd.embarcadero.com revealed there is a non-installer file short enough (~72 kibibytes) for Uptime robot to check, so it now verifies it can access these:
