+## combine commands with *xargs*
+
+Some commands (e.g. `chmod`) can't handle input via pipe and require the input as arguments. `xargs` takes the standard input as list of arguments seperated by spaces or newlines and executes the given command with the input parsed to a list of arguments.
+
+Usage:
+```bash
+find . -type f | xargs chmod 644
+```
