  Escape sequence - Wikipedia, the free encyclopedia
An escape sequence is a series of characters used to trigger some sort of command state in computers and their attached peripherals.
An example of a non-modal escape sequence control language is the VT100, which used a series of commands prefixed by the Control Sequence Introducer, escape-[.
There is a fine line between a set of control characters and an escape sequence that may not exist at all.

 Escape character - Wikipedia, the free encyclopedia
In alphabet coding schemes, a specially designated character, the occurrence of which in the data signifies that one or more of the characters to follow are from a different character code, i.e., have meanings other than normal.
In a text-control sequence of characters, a control character that indicates the beginning of the sequence and the end of any preceding text.
Escape characters are also used to sidestep a literal character when it would have a special meaning and you want the ordinary meaning.

In atoms (enclosed by single quotes) and strings it is possible to use escape sequences and symbolic control characters.
An escape sequence is an octal or hexadecimal number, for instance \165 or \x67, of which the decimal value is calculated and the complete sequence is replaced by a single character with the same ASCII value as the calculated decimal value.
All valid characters, or until a backslash character is detected, are treated as part of the escape sequence.

An escape sequence is a control instruction which orders the shell to execute a specific step.
To prevent the text after the prompt from being green, we are closing the escape sequence with \033[0m, which is the default color of the shell.
As previously mentioned, the '0' after the first escape sequence is the default color setting for the text of the shell prompt.

The executability of all basic statements in the main sequence is constrained to the non-executability of all guard statements of the escape sequence.
If all guards of the escape sequence remain unexecutable throughout the execution of the main sequence, the escape sequence as a whole is skipped.
Following the semantics model, the guard statements of an escape sequence are assigned a higher priority than the basic statements from the main sequence.
