linux - xargs (or something else) without space before parameter -

i execute (git squash):

git rebase -i head~3 

extracting 3 git log:

git log | blabla | xargs git rebase -i head~ 

this not work because xargs inserts space after head~.

the problem want alias command, cannot use

git rebase -i head~`git log | blabla` 

because number evaluated when define alias.

i don't have use xargs, need alias (preferably not function).

you can use -i option of xargs:

git log | blabla | xargs -i% git rebase -i head~%
