2. Escape is shorthand for an escape character. An escape character is a single backward slash ( \ ) in Linux, programming, and regular expressions that treated as text and not a function. It can also be used to perform a special function. Below are some examples of how an escape could be used.
\" or \'
The above example treats the quote character as a quote character and not a beginning or end container. For example, in programming languages such as Perl, this is required to print text to the screen containing a quote. In other words, the command print "Example of a \" quote."; would print Example of a " quote. Without escaping the quote, the Perl script would generate an error because of the extra quote.
This next example is similar to the first example because the period is also a wildcard, which represents any single character. So, if you need to match a period in a regular expression and not every character, you must escape it to be recognized as a period.
When a file name or directory needs a space in Linux, you can use a backward slash followed by a space, to escape the space in a name. If this isn't done, Linux treats anything after the space as an option or additional command.
Finally, escape characters are also used in escape sequences, to create a function or command. For example, the above \n would create a newline character to the file or screen. See our escape sequence page for additional examples.
3. Short for escalation, esc is used to describe or refer to an escalation number dealing with an important customer related issue.
