Why not ask git itself? When you rebase with git-bash, it says:

pick 512b1d7 (some comment)
# Rebase 621b2e4..512b1d7 onto 621b2e4 (1 command)
#
# Commands:
# p, pick  = use commit
# r, reword  = use commit, but edit the commit message
# e, edit  = use commit, but stop for amending
# s, squash  = use commit, but meld into previous commit
# f, fixup  = like "squash", but discard this commit's log message
# x, exec  = run command (the rest of the line) using shell
# d, drop  = remove commit
# l, label  = label current HEAD with a name
# t, reset  = reset HEAD to a label
# m, merge [-C  | -c ]  [# ]
# .       create a merge commit using the original merge commit's
# .       message (or the oneline, if no original merge commit was
# .       specified). Use -c  to reword the commit message.
#
# These lines can be re-ordered; they are executed from top to bottom.
#
# If you remove a line here THAT COMMIT WILL BE LOST.
D:/code/fenixito-legacy-api/.git/rebase-merge/git-rebase-todo [unix] (11:57 23/10/2019)                                         1,1 start
"D:/code/xxx/.git/rebase-merge/git-rebase-todo" [UNIX] 27L, 1170C

So you see:

s, squash = use commit, but meld into previous commit

f, fixup = like "squash", but discard this commit's log message
