    xargs(1)

    +
    xargs [opts] [cmd [init-args]]
+    -l [<num>]   maximal number of lines per cmd invocation
+                 if <num> it not provided, num=1 is assumed
+    -I <str>     replace <str> in the [init-args] with the arg;
+                 this implies -l, and hence processes one arg at a time
+
    +

    Example

    +

    Collect arguments and prefix them with another option.

    +
    # Using -l to process one arg at a time.
+eval strace -f (find /dev -name 'std*' | xargs -l echo -P | xargs) ls
+
+# Using -I to place the arg at the specified location.
+eval strace -f (find /dev -name 'std*' | xargs -I {} echo -P {}) ls
+
+# Both commands achieve the same thing and result in something like:
+#   eval strace -f -P /dev/stdin -P /dev/stdout -P /dev/stderr ls
