Let me show you the manual entry again:
--replace[=replace-str], -I replace-str, -i[replace-str]
Replace occurences of replace-str in the initial
arguments with names read from standard input.
Also, unquoted blanks do not terminate arguments.
If replace-str is omitted, it defaults to "{}" (like
for 'find -exec'). Implies -x and -L 1.
So you either do:
echo -e "file1\nfile2\nfile3" | xargs -i echo '{}' blah
or echo -e "file1\nfile2\nfile3" | xargs -i echo '{}' blah/'{}'
or echo -e "file1\nfile2\nfile3" | xargs -i'**' echo '**' blah
or echo -e "file1\nfile2\nfile3" | xargs -I '**' echo '**' blah
This is correct:
xargs -i'{}'
or xargs -I '{}'
This is not:
xargs -i '{}'
Compare this to the manual entry to verify. The distinction is necessary
and important to allow for an '{}' default replace-str. Otherwise xargs
wouldn't know whether the next argument is in fact the replace-str or the
command to run !
