Powershell Curl Logs Signal Strength of Cable Modem

IMPORTANT: You need Windows PowerShell to run this command - in your Windows Command Prompt, type powershell Create a log file of your Motorola Surfboard SB6141 downstream signal strengths. Uses the built-in curl to request signal strength data from your SB6141 cable modem. HTML page 192.168.100.1/cmSignalData.htm has the signal strength numbers for the 8 downstreams. Some HTML/DOM processing parses out the 8 values from the above page. The eight extracted signal strengths are then logged to a file. A small while-loop watches the clock & repeats the process every 10 seconds. Show Sample Output

Auto-kill auto-spawned process

Given a process name (kdiff3 in this example) that keeps auto-spawning/starting, auto-kill until it stops, assuming there is an upper limit (if not, reboot). This was beneficial after I clicked the DIFF button in a git GUI on a merge commit. 2000+ files were being opened one after the other in my diff program (kdiff3). Each time I closed one (or quit Kdiff3), the next file would be auto-opened in Kdiff3.

Fetch every font from dafont.com to current folder

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

Install pip with Proxy

Installs pip packages defining a proxy

Switch to the previous branch used in git(1)

Very useful if you keep switching between the same two branches all the time.

Delete all files by extension

This is a correction to https://www.commandlinefu.com/commands/view/22134 Use `-name` instead of `-iname`, because case-sensitivity is probably important when we're dealing with filenames. It's true that extensions are often capitalised (e.g., "something.JPG"), so choose whatever's appropriate. However, what is appropriate is the quoting of the name pattern, so the shell doesn't expand it incorrectly. Finally, `-delete` is clearer.

Convert CSV to JSON

Replace 'csv_file.csv' with your filename.
