I have an Android tablet that I got a terminal program from Google Play Store. When I issue the "ps" command, it shows various names for the users running the processes. There is no /etc/passwd file on this machine so I'm wondering where it gets the user names from.
Shell – From where does “ps” on Android get user names

Yes, I've got the solution. See there were 2 options for connecting tablet. 1) Media device (MTP) 2) Camera (PTP)
I'd been using the 1st one where via command line I was failing to do & via GUI, I wasn't able to retain the time stamp. This option uses mtp to connect.
Then yesterday, it stroked my mind & I connected via the 2nd option , i.e. camera. Now via GUI (shotwell software), I was able to import the files.
Then in nautilus, I found it was connected not via mtp but gphoto2.
Now I was able to use the command line & copy via cp -a retaining the time stamp & it worked. Now I know all command line commands like tar will work as with any external HDD or pen-drive. A great relief!

pswill get the names with thegetpwuid(3)function (see here).On android, that will generate pwd entries on the fly, rather than fetching them from some file.
