getting error while using "su" command

Question

I try to make batch file to run adb commands. I want to use su -c, but I get the error:

 su: invalid uid/gid '-c'.

I saw somewhere that my su version doesn't support -c, how can I enable this?

In batch file it should be like this:

adb shell "su 0 <command args>"

For example:

adb shell "su 0 mount -o rw,remount /system"

0 is uid for root

The standard Android su is much simpler than its regular linux counterpart. It does not support any commands other than -c - so it's become redundant.

usage: su [UID[,GID[,GID2]...]] [COMMAND [ARG...]]

Somehow, as I said, my 'su' doesn't support even '-c'. (I use Android)

su -c 'command args' becomes su 0 command args in Android

ok. so if I want to run commands (using batch script) from a wanted and specific path in my devices, how can I do it without it?

@AlexP. do you know what 0 means here?

@AlirezaA.Ahmadi 0 is the user ID you want to run the command as, so 0 for root.
