# Immediately before that newline, 0x09 is printed - in ASCII, the

|
# horizontal tab. If xargs' -I option is used, tr(1p) should used to delete

|
# that tab. If the tab is left as part of input, OpenBSD's xargs(1)

# implementation has been observed to strip it along with the other
|

# trailing whitespace (the newline), but Busybox's and GNU's xargs(1)

|
|
# implementations strip off the trailing tab if `-I` is not used. The POSIX
