Running strace on the bash shell that is instructed to run mkdir provided this output which shows lots of stats prior to execve the actual mkdir binary:

 2766 [pid 17371] stat(".", 0750, st_size=17262, ...) = 0
 2767 [pid 17371] stat("/usr/local/sbin/mkdir", 0x7ffd87aad0a0) = -1 ENOENT 2767 (No such file or directory)
 2768 [pid 17371] stat("/usr/local/bin/mkdir", 0x7ffd87aad0a0) = -1 ENOENT (No such file or directory)
 2769 [pid 17371] stat("/usr/bin/mkdir", 0755, st_size=51136, ...) = 0
 2770 [pid 17371] stat("/usr/bin/mkdir", 0755, st_size=51136, ...) = 0
 2771 [pid 17371] access("/usr/bin/mkdir", X_OK) = 0
 2772 [pid 17371] stat("/usr/bin/mkdir", 0755, st_size=51136, ...) = 0
 2773 [pid 17371] access("/usr/bin/mkdir", R_OK) = 0
 2774 [pid 17371] stat("/usr/bin/mkdir", 0755, st_size=51136, ...) = 0
 2775 [pid 17371] stat("/usr/bin/mkdir", 0755, st_size=51136, ...) = 0
 2776 [pid 17371] access("/usr/bin/mkdir", X_OK) = 0
 2777 [pid 17371] stat("/usr/bin/mkdir", 0755, st_size=51136, ...) = 0
 2778 [pid 17371] access("/usr/bin/mkdir", R_OK) = 0
 2779 [pid 17371] execve("/usr/bin/mkdir", ["mkdir", "/tmp"], 0x557ec7e15920 /* 5 vars */) = 0

My question is: Is it normal (and if so for what reason) is /usr/bin/mkdir stat()ed a lot?
The output lines are numbered and in particular I wonder what sense will line 2776 make once 2771 was run already. Also I was under the impression bash could have saved all systemcalls from 2770 onward to the final execve as the stat should have provided the information at once? What am I missing?

I have since sought an explanation and checked how an alternative shell the dash shell would behave it also shows some stat()ing :

 2792 [pid 17372] stat("/usr/local/sbin/mkdir", 0x7ffc66010b50) = -1 ENOENT (No such file or directory)
 2793 [pid 17372] stat("/usr/local/bin/mkdir", 0x7ffc66010b50) = -1 ENOENT (No such file or directory)
 2794 [pid 17372] stat("/usr/sbin/mkdir", 0755, st_size=51136, ...) = 0
 2795 [pid 17372] execve("/usr/sbin/mkdir", ["mkdir", "/run"], 0x55d8d3453bb8 /* 6 vars */) = 0

I am aware that the lines 2792,2793, similar to the lines 2767, 2768are because of searching the executable in the various directories in the currentPATH`.

If this is discounted then dash only does one single stat and bash does 10. Again raising the question: is this normal?
