It is hard to for anyone who like to dig deeper in AIX.
AIX commands are divided by three layers:
High Level
Intermediate
Lower Level
Usually only "High Level" commands have good manual page and documents.
For example,oslevel is the "High Level" command. But we can not find any documents about
rm_mlcache_file which oslevel depends on.
#grep rm_mlcache_file /usr/bin/oslevel
/usr/bin/rm_mlcache_file
When I tried to find more information about nimsh, I can not find anything for nimsh methods.
