Do this instead:
vi `cat list`
cat list - gives the output of the file which is the three filenames
`cat list` - executes this command and feeds its output to the input of
your next command
So the resulting command ends up being "vi ./a ./b ./c" which opens up
the 'a' file and you will be able to move to the next file with the :n
option.
xargs is effectively running a for loop on each unique item in the
output of the previous command (cat list). vi expects to be run on one
file at a time and needs to be associated with a terminal session in
prder to be able to get input from you (either text or commands) to
apply to the file.
