Powershell Escape characters.

A while back I couldn't find a definitive list of the regular escape characters for PowerShell. So I wrote a program that would generate them all and give me a clue for each letter what I might get.

I have since lost the code, and the output was a little cryptic, particularly with nonprinting characters like Tab, space, Carriage return, Line feed, and Bell.

The Bell character "`a" was interesting. But it doesn't always make it back to me from a session.

The first 2 are for the quoting characters, if you need to embed a quote in the string you are creating, this is one easy way to get them placed literally, and not interpreted by the compiler.

As it was noted it the PluralSight Gotcha video, these are limited to Powershell, you will find if you pass a string to .net or some other software, it may have a different escape character, and different behavior.


Notes:

• Single quote ' means that what is enclosed is Literal not to be processed
• Double quote " means that what is enclosed is interpreted.
• The Backtick is ` and not the single quote '  (apostrophe)
• The key is typically on the left side of the keyboard upper left corner. 

PowerShell Escape character table:

39	'	`'	Single Quote	39
48	0	`0	Null	00
96	`	``	Back-tick	96
97	a	`a	Bell	07
98	b	`b	Backspace	08
102	f	`f	Line Feed	12
110	n	`n	New Line	10
114	r	`r	Carriage Return	13
116	t	`t	Tab	09
118	V	`v	Vertical tab	11
