    more is a legitimate program (it reads a file and writes it out one page at a time), if it is the real more. It is a memory hog in that (unlike the more advanced pager less) it reads the entire file into memory.

    I did an experiment to see if I could get the real more to show similar fds to you. I piped yes "" | head -n10000 >/tmp/test, then ran more < /tmp/test 2>/dev/null. Then I ran ls -l /proc/`pidof more`/fd.

    Results:

    lr-x------ 1 andrew andrew 64 Nov  5 14:56 0 -> /tmp/test
    lrwx------ 1 andrew andrew 64 Nov  5 14:56 1 -> /dev/pts/2
    l-wx------ 1 andrew andrew 64 Nov  5 14:56 2 -> /dev/null
    lrwx------ 1 andrew andrew 64 Nov  5 14:56 3 -> 'anon_inode:[signalfd]'
    

    I think this suggests your open files are probably consistent with the real more when errors are piped to /dev/null. Most likely, you were running something that called more to output something to you (or someone else logged in on a PTY) that had been written to /tmp/RG3tBlTNF8. Next time, you could find the parent of the more process, or look up what else is attached to the same PTS with the fuser command.

      Thank you after reading the comments i am relieved: I had saved a 3 page fully worded .odt as as .fodt and opened it with a text editor; but then again all the files had been closed and i deleted the file in question a at least 30 mins before i noticed the process; regardless thank you
