From: Zach Riggle <firstname.lastname@example.org> To: Zsh Users <email@example.com> Subject: Builtins like "exec" redirection are not printed with xtrace Date: Wed, 11 May 2022 01:48:30 -0500 [thread overview] Message-ID: <CAMP9c5kA=dQHFESte76nZuAZ=tHbCZNwgTPR1sKnQsrrV6yjVQ@mail.gmail.com> (raw) [-- Attachment #1: Type: text/plain, Size: 486 bytes --] It seems that the following produces no output #!/bin/zsh setopt xtrace exec 1>/dev/null Is there a reason that xtrace does not show the exec line? Similarly, other commands with I/O redirection seem to not be logged in xtrace, e.g. $ cat xt #!/bin/zsh setopt xtrace head -c 8 /bin/sh | xxd > /dev/null $ zsh xt +xt:3> head -c 8 /bin/sh +xt:3> xxd Is there a way to get xtrace (or another option) to log the I/O redirection? *Zach Riggle* [-- Attachment #2: Type: text/html, Size: 1222 bytes --]
