Yum can also read commands from a text file and execute it one by one. This is very helpful when you have multiple systems. Instead of executing the same command on all the systems, create a text file with those commands, and use ‘yum shell’ to execute those commands as shown below.
# cat yum_cmd.txt
repolist
info nfs-utils-lib.x86_64

# yum shell yum_cmd.txt
