Nested quotes often become an issue using the eval keyword. [1] The eval function is a function that converts and interprets a string as actual JavaScript code, and runs that code. If that string is specified as a literal , then the code must be written as a quote itself (and escaped accordingly).
In the case of multiple possible completions, some command-line interpreters, especially Unix shells, will list all possible completions beginning with those few characters. The user can type more characters and press Tab ↹ again to see a new, narrowed-down list if the typed characters are still ambiguous, or else complete the command ...

The use of the triple-quotes to comment-out lines of source, does not actually form a comment. [19] The enclosed text becomes a string literal, which Python usually ignores (except when it is the first statement in the body of a module, class or function; see docstring). Elixir
Generally, an escape character is not a particular case of (device) control characters, nor vice versa.If we define control characters as non-graphic, or as having a special meaning for an output device (e.g. printer or text terminal) then any escape character for this device is a control one.
PowerShell: The backtick is used as the escape character. For example, a newline character is denoted `n . Most common programming languages use a backslash as the escape character (e.g., \n ), but because Windows allows the backslash as a path separator, it is impractical for PowerShell to use backslash for a different purpose.
This one-liner program is a glob pattern matcher. It understands the glob characters *, meaning zero or more characters, and ?, meaning exactly one character, just like most Unix shells. Run it with two args, the string and the glob pattern. The exit status is 0 (shell true) when the pattern matches, 1 otherwise.
In computing, alias is a command in various command-line interpreters (), which enables a replacement of a word by another string. [1] It is mainly used for abbreviating a system command, or for adding default arguments to a regularly used command.
