But, this time it will preserve the newline. $ xargs -d\nĪfter you type the above, press ctrl+d, which will echo the string back to you on stdout as shown below. In the following example, when you use the -d\n, it will preserve newline delimiter in the output, and display the output exactly as it was typed. So, the output in the previous example was combined into a single line. In the previous example, even though the input contained a \n (newline) after ‘Hi,’ but the echoed output did not contain the newline ‘\n’. Specify Delimiter Using -d optionĭelimiters can be applied so that each character in the input is taken literally using -d option in xargs. When you type xargs without any argument, it will prompt you to enter the input through stdin:Īfter you type something, press ctrl+d, which will echo the string back to you on stdout as shown below. The following is what happens when you execute xargs without any argument, or when you execute it without combining with any other commands. The xargs command (by default) expects the input from stdin, and executes /bin/echo command over the input. But, once you understand these concepts, you can come-up with your own clever examples of xargs to solve various command line problems. These example will help you understand the basics of how xargs command works. This tutorials explains the usage of xargs command using few simple examples. The xargs command is extremely useful when we combine it with other commands.
