The process.title property is an inbuilt application programming interface of the process module which is used to get and set the title of the process.
Syntax:
process.title
Return Value: This property returns a string value that specifies the title of the process, current value is ‘ps’.
Note: Assigning the new value to this property will modify the current value. The different platforms can impose a restriction on the maximum length of process title.
Below examples illustrate the use of process.title property in Node.js:
Example 1:
// Node.js program to demonstrate the // process.title property // Include process module const process = require( 'process' );
// Printing process.title property value console.log( "PID: " + process.pid +
" process title is " + process.title);
|
Output:
PID: 8852 process title is Command Prompt - node title_1
Example 2:
// Node.js program to demonstrate the // process.title property // Include process module const process = require( 'process' );
// Printing process.title property value console.log( "Before modification: PID: " + process.pid
+ " process title is " + process.title);
// Setting new process title value process.title = "gekchosCustomProcess" ;
// Printing process.title value after modification console.log( "After modification: PID: " + process.pid
+ " process title is " + process.title);
|
Output:
Before modification: PID: 14012 process title is Command Prompt - node title_2 After modification: PID: 14012 process title is gekchosCustomProcess
Note: The above program will compile and run by using the node filename.js
command.
