Useful string manipulation examples for bash and zsh

I need very often to modify filenames or replace/delete their parts across huge number of files. I was using sed command for these purposes but recently I have found out that all these tasks can be easily done directly in bash (or zsh) because both of them support so called string manipulation operations.

String manipulations

Define some example string:

$ file=some_file_name.txt

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

Prefixed style properties

-ms-accelerator

The -ms-accelerator property sets or retrieves a string that indicates whether the object represents a keyboard shortcut.

-ms-accelerator: false | true

Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.

video::webkit-media-controls-timeline {
  background-color: lime;
}

video /deep/ input[type=range] {
