Oracle Linux xargs Command

This manual page documents the GNU version of xargs.  xargs reads items from the standard input, delimited by blanks (which can be protected with double or single quotes or a backslash) or newlines, and executes the command (default is /bin/echo) one or more times with any initial-arguments followed by items read from standard input.  Blank lines on the standard input are ignored.

-p Prompt the user about whether to run each command line and read a line from the terminal. 
-I replace-str Replace  occurrences  of replace-str in the initial-arguments with names read from standard input.  Also, unquoted blanks do not terminate input items; instead the separator is the newline character.


Examples:
List all *.dat files in the current directory and zip each file.
ls *.dat | xargs -I {} zip ./{}.zip {}

Generates a compact listing of all the users on the system.
cut -d: -f1 < /etc/passwd | sort | xargs echo
