Try the xargs command:
cat result | xargs yum remove

Try the xargs command:
cat result | xargs yum remove
You could probably also do something like:
# for line in `cat packages.txt`; do echo remove $line >> yumshell.txt; done # echo run >> yumshell.txt # yum shell yumshell.txt
That might be a bit faster as it'll only do the dep-solving one time.

Or, without the tempfile and in one line:
# { for line in `cat packages.txt`; do echo remove "$line"; done; echo run; } | yum shell
That might be a bit faster as it'll only do the dep-solving one time.
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.

Try the xargs command:
cat result | xargs yum remove
OR ...
yum remove `cat result`

Try the xargs command:
cat result | xargs yum remove
OR ...
yum remove `cat result`
The winner! And if running a modern bash
yum remove $(cat result)

Interesting. According to the bash man page `command` and $(command) are slightly different (in regards to backslashes). I always assumed they were identical in every way.
======================== Command Substitution
Command substitution allows the output of a command to replace the command name. There are two forms:
$(command) or ‘command‘
Bash performs the expansion by executing command and replacing the command substitution with the standard output of the command, with any trailing newlines deleted.
...
*When the old-style backquote form of substitution is used, backslash retains its literal meaning except when followed by $, ‘, or .* The first backquote not preceded by a backslash terminates the command substitution. When using the $(command) form, all characters between the parentheses make up the command; none are treated specially. ========================
