Summary: Whitespace parsing differs with and without -i Project: findutils Submitted by: None Submitted on: Thu 09 Apr 2020 05:55:59 PM UTC Category: xargs Severity: 3 - Normal Item Group: Wrong result Status: None Privacy: Public Assigned to: None Originator Name: Ryan Moore Originator Email: rmo...@aurora.tech Open/Closed: Open Release: 4.7.0 Discussion Lock: Any Fixed Release: None _______________________________________________________ Details: I would expect this to use -n1 to separate the whitespace-delimited parameters "a" and "b" and "c" to print 3 separate lines: root@rmoore:~# echo "a b c" | xargs -n1 -i{} echo foo {} foo a b c If I manually specify a space as the delimiter, it works as expected (and gives an extra CR with the last line, since it's now "c\n"): root@rmoore:~# echo "a b c" | xargs -d\ -n1 -i{} echo foo {} foo a foo b foo c If I run without -I{} as a substitution, it works as expected (and prints {} explicitly): root@rmoore:~# echo "a b c" | xargs -n1 echo foo {} foo {} a foo {} b foo {} c Version info, from Ubuntu 16.04 (also confirmed on 18.04): root@rmoore:~# xargs --version xargs (GNU findutils) 4.7.0-git Copyright (C) 2016 Free Software Foundation, Inc.
