Or, without the tempfile and in one line:

# { for line in `cat packages.txt`; do echo remove "$line"; done; echo
run; } | yum shell

Not really. "xargs" will by default call yum remove with a long line
of parameters. It will only break that into multiple commands if the
line is too long (too many parameters or too many characters). man
xargs for the details, see the -n and -s parameters.
