On centos 7 (docker), I see yum install command with several packages succeeds even if some are not found. This is nasty for scripting :-(

(in this example golang not found because I didn't add EPEL repo)

[root@1ec73c6c476b /]# yum install golang nano

[root@1ec73c6c476b /]# echo $?
0

It only exits 0 if all specified packages are missing:

[root@1ec73c6c476b /]# yum install foo
Loaded plugins: fastestmirror, ovl

 * base: centos.interhost.net.il

Error: Nothing to do

[root@1ec73c6c476b /]# yum install golang foo

Error: Nothing to do

According to https://access.redhat.com/solutions/321603, the latter behavior is new in RHEL 6, per this changelog: https://github.com/rpm-software-management/yum/blob/master/ChangeLog#L3749-L3762

... If all package(s) are "not found", yum turns the message "Nothing to do" into an error (returns 1, atm). ...thus:

1. 
   yum install -y a b && echo worked
   
   This will echo "worked" if either a or b is installed after yum finishes, but tries to install both.


2. 
   yum install a && yum install b && echo worked
   
   This will echo "worked" if both are installed (and if a is not available, b will not even try to be installed).

But presumably, a single yum install a b is faster and in complex cases better at dependency resolution than yum install a && yum install b (?)

Q: Is there any flag/config to install many packages in one yum invocation, requiring all to be found for success?
