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. ========================
