Ls: cannot access /usr/share/man/man8/useradd.8.gz: No such file or directory Package 2:shadow-utils-4.1.5.86_64 already installed and latest versionĪnd, in fact, the binaries (e.g. # yum whatprovides /usr/share/man/man8/useradd.8.gzĢ:shadow-utils-4.1.5.86_64 : Utilities for managing accounts and shadow password filesįilename : /usr/share/man/man8/useradd.8.gz The best part of this is that what I really wanted right this minute was the man page for the useradd command, which isn't even in that RPM. I can create files in /usr/share/man/man1p/, so it's probably not some Docker virtual filesystem weirdness.

I used rpm to check that man-pages was supposed to include the ls man page, and it looks like it does: # rpm -ql man-pages | grep -w lsīut it doesn't look like it was actually installed: # man 1p lsĪnd it doesn't seem to be anywhere else on the filesystem, either. > Package man-pages.noarch 0:3.53-5.el7 will be installed Loading mirror speeds from cached hostfile

Per this Serverfault answer, I installed the man-pages RPM, and that seemed to go fine: # yum install -y man-pages Out of the box, it doesn't have much: # man ls I have a minimal Centos 7 Docker image, and I'm trying to get some man pages on it to help in debugging my Dockerfile.
