DuckDuckGo and Google search "inotifywait" "adb".

Could execute Termux binary, but I prefer avoiding to do so.

Maybe can adb push Termux inotifywait:

On Termux:

which inotifywait

/data/data/com.termux/files/usr/bin/inotifywait

adb root
adb pull /data/data/com.termux/files/usr/bin/inotifywait

/data/data/com.termux/files/usr/bin/in...pped. 2.4 MB/s (24464 bytes in 0.010s)

adb unroot

restarting adbd as non root

adb push inotifywait .
Output:

DuckDuckGo and Google search Linux specify .so to executable.

The Server Fault answer 279069:

echo $LD_LIBRARY_PATH

does not return anything.

The Server Fault answer 699902:

LD_LIBRARY_PATH=. ./inotifywait                                                                                     

CANNOT LINK EXECUTABLE "./inotifywait": library "libc++_shared.so" not found: needed by /data/local/tmp/libinotifytools.so in namespace (default)

If proceed similarly with libc++_shared.so.

LD_LIBRARY_PATH=. ./inotifywait

I uninstalled Termux on Samsung Galaxy A53 to avoid bias.

Could cache on disk or RAM URLs to avoid redundant calls as currently due to inotify-tools, but it is quite unclear how to do so.

To ease process may want to leverage Termux install from ADB. However, it involves adb root which does not seem safe, could just copy to /data/local/tmp/, then unroot.

Output: 
adbd is already running as root

shell: does not work as wanted.

If proceed in adb shell it works as wanted.

adb unroot

restarting adbd as non root
