xargs is a unix command for assigning various inputs to different pther unix commands.

Executing one line at a time

To execute commands for each of the line feed, use the following option:-n 1. For example:

ls | xargs -n 1 -i echo {}

Note that one must supply the -i option, so that {} can become the placeholder for content piped from the previous process.

In certain cases, when the input data embeds separators, one needs to turn on the -0 option. For example:

ls | xargs -0 -n 1 cp {} /targetDirectory
