+-x <cmd>::
+--exec <cmd>::
+ Append "exec <cmd>" after each line creating a commit in the
+ final history. <cmd> will be interpreted as one or more shell
+ commands.
++
+This option can only be used with the `--interactive` option
+(see INTERACTIVE MODE below).
++
+You may execute several commands by either using one instance of `--exec`
+with several commands:
++
+ git rebase -i --exec "cmd1 && cmd2 && ..."
++
+or by giving more than one `--exec`:
++
+ git rebase -i --exec "cmd1" --exec "cmd2" --exec ...
++
+If `--autosquash` is used, "exec" lines will not be appended for
+the intermediate commits, and will only appear at the end of each
+squash/fixup series.
