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
