How to tar a directory including dotfiles, but omitting all reference to the directory itself
I want to back up home directories including the usual array of dotfiles, but I do not want the directory itself, or its permissions to be backed up or even mentioned. So, if I have a structure like
homedir
.dotfile
somesubdir
subfile
outerfile
I want a tar that looks like this:
.dotfile
somesubdir
subfile
outerfile
Note the absense of any reference to homedir, and not even a ./ to be seen.
I actually have a solution (posted below) but when I tried to tack it onto the question that made me think of it, some moderator said it needed its own question. So here it is, and I hope it's useful.

Using Bash 4.4.19 and GNU tar 1.29, the following works. 'dotglob' makes * recognize dots as well as letters, while 'GLOBIGNORE' is set to ignore "." and "..". The curly braces allow me to direct the output to the current directory, while the pushd and popd make the tar happen where the stuff is. I don't use tar's -C option because that messes up the "*" glob.
shopt -s dotglob
GLOBIGNORE=".:.."
{
pushd homedir >/dev/null
tar --create --file=- *
popd >/dev/null
} >inner.tar
shopt -u dotglob
note that the output file is set to "-" which means standard output which winds up going to the file inner.tar. The redirections to /dev/null silence the mention of the directory changes.
