It's outputing to stderr not stdout, you can catch it with 2> instead of > for redirection. As to wether this is a desirable behaviour, I'll let others comment
Thanks that's super helpful, I can confirm this works:
$ U=$(dnf check-release-update --latest-only --version-only 2>&1)
$ echo $U
2023.2.20231030
$
I am strongly in the "this is undesirable behavior camp" - if we are unable to correct this antipattern then having a note in the help output would be a huge help to others.
Yeah, this seems less than ideal behavior here.
+1, we should fix this.
Description I am trying to automate detection of new Amazon Linux2023 versions being available using
dnf check-release-update
and it looks like the output of that command is not sent to stdout. I would assume that I could invoke the command, then assign a variable to the output of it. While text does print to the console, variable assignment or redirection does not work as expected.To Reproduce Steps to reproduce the behavior:
Expected behavior I would expect the
check-release-update
plugin to allow redirection of stdout so that it can be assigned to a variable, or redirected to a file, etc. as any other standard Unix utility would function.
