• discovered yum. (Yellowdog Updater, Modified) It's a package manager for Red Hat's RPM package system. The name YellowDog, is from a Mac Linux distro in 1999. Yellow Dog Linux seems still around.
• on Fedora Linux, man {shutdown, halt, poweroff, reboot} says: “These are legacy commands available for compatibility only”. So, what is the modern command?
Answer: there doesn't seem to be a standard among Linuxes. (See “Replacement for init” at Init.) Fedora uses systemd.
Note that in Ubuntu, the man page for “shutdown” is different, and doesn't come with such note.
• discovered wmctrl. This seems to be Linux's analog of AutoHotkey for Microsoft Windows. See: Linux: Keyboard Layout, Keymapping, Keybinding, Tools ⌨.
here's more food for my wrath. todo tomorrow.
• check if Linux ps still silently truncate lines. 〔☛ Unix, RFC, Line Truncation〕
• check if tar still have problem if file path is long. (⁖ nested dir each with 200 char in file name)
• check robustness of tar when filenames are full of unicode. 〔☛ Unicode Support in File Names: Windows, Mac, Emacs, Unison, Rsync, USB, Zip〕
• check if you can still put random char in file names, such as control sequence, beep. 〔☛ On Unix Filename Characters Problem〕
• check how robust is Linux with unicode. Name files with Chinese and math symbols. (and if it requires me to dig into shell locale env var shit, then it's shit.)
• check/review the unix startup process, the rc scripts. 〔☛ Init〕
• heard that ash is new simple shell for start up. Dig it.
• gotta review my unix networking stuff. ifconfig, whois, dig, ping, ... i understand many of these became obsolete.
• review the password creation, password file, user account creation, uid, gid, stuff.
• review how to find the processes that are locking files.
• run my elisp/perl/python scripts on website's 5k files, see how fast it runs inside virtual machine vs Windows native. (if good, i might start to do all my web site inside Linux.)
lol. The old unixism lives.
[xah@localhost~]$ sudo yum install xmonad-gnome We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things: #1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility. [sudo] password for xah:
“great power comes great responsibility”? F��� the Red White Blue culture shit. That phrase amounts to being a execuse to meddle with other's business.
this officious advice from sudo happened in Fedora, but not in Ubuntu. For Dummies always win. At least better than the drivels from unix f���heads. 〔☛ What is a Tech Geeker?〕
