####### # # E-scripts on the Linux kernel. # # Note 1: use the eev command (defined in eev.el) and the # ee alias (in my .zshrc) to execute parts of this file. # Executing this file as a whole makes no sense. # An introduction to eev can be found here: # # (find-eev-quick-intro) # http://angg.twu.net/eev-intros/find-eev-quick-intro.html # # Note 2: be VERY careful and make sure you understand what # you're doing. # # Note 3: If you use a shell other than zsh things like |& # and the for loops may not work. # # Note 4: I always run as root. # # Note 5: some parts are too old and don't work anymore. Some # never worked. # # Note 6: the definitions for the find-xxxfile commands are on my # .emacs. # # Note 7: if you see a strange command check my .zshrc -- it may # be defined there as a function or an alias. # # Note 8: the sections without dates are always older than the # sections with dates. # # This file is at <http://angg.twu.net/e/linux.e> # or at <http://angg.twu.net/e/linux.e.html>. # See also <http://angg.twu.net/emacs.html>, # <http://angg.twu.net/.emacs[.html]>, # <http://angg.twu.net/.zshrc[.html]>, # <http://angg.twu.net/escripts.html>, # and <http://angg.twu.net/>. # ####### # Old version: # (find-es "kernel") # (find-zsh "installeddebs | sort | grep linux") # (find-zsh "availabledebs | sort | grep linux") # «.single» (to "single") # «.makedev» (to "makedev") # (find-status "linux-base") # (find-vldifile "linux-base.list") # (find-udfile "linux-base/") # (find-status "linux-generic") # (find-vldifile "linux-generic.list") # (find-udfile "linux-generic/") # (find-status "linux-headers-4.4.0-140") # (find-vldifile "linux-headers-4.4.0-140.list") # (find-udfile "linux-headers-4.4.0-140/") # (find-status "linux-headers-4.4.0-140-generic") # (find-vldifile "linux-headers-4.4.0-140-generic.list") # (find-udfile "linux-headers-4.4.0-140-generic/") # (find-status "linux-headers-4.4.0-141") # (find-vldifile "linux-headers-4.4.0-141.list") # (find-udfile "linux-headers-4.4.0-141/") # (find-status "linux-headers-4.4.0-141-generic") # (find-vldifile "linux-headers-4.4.0-141-generic.list") # (find-udfile "linux-headers-4.4.0-141-generic/") # (find-status "linux-headers-generic") # (find-vldifile "linux-headers-generic.list") # (find-udfile "linux-headers-generic/") # (find-status "linux-image-4.4.0-140-generic") # (find-vldifile "linux-image-4.4.0-140-generic.list") # (find-udfile "linux-image-4.4.0-140-generic/") # (find-status "linux-image-4.4.0-141-generic") # (find-vldifile "linux-image-4.4.0-141-generic.list") # (find-udfile "linux-image-4.4.0-141-generic/") # (find-status "linux-image-extra-4.4.0-140-generic") # (find-vldifile "linux-image-extra-4.4.0-140-generic.list") # (find-udfile "linux-image-extra-4.4.0-140-generic/") # (find-status "linux-image-extra-4.4.0-141-generic") # (find-vldifile "linux-image-extra-4.4.0-141-generic.list") # (find-udfile "linux-image-extra-4.4.0-141-generic/") # (find-status "linux-image-generic") # (find-vldifile "linux-image-generic.list") # (find-udfile "linux-image-generic/") ##### # # Booting into single user mode # 2019apr21 # ##### # «single» (to ".single") # (find-es "kernel" "boot-parameters") # (find-status "linux-doc") # (find-vldifile "linux-doc.list") # (find-udfile "linux-doc/") # (find-udfile "linux-doc/kernel-parameters.txt.gz") # (find-linuxdocfile "kernel-parameters.txt.gz" "S" "[KNL] Run init in single mode") # (find-linuxdocfile "kernel-parameters.txt.gz" "init=" "instead of /sbin/init") (code-c-d "linuxdoc" "/usr/share/doc/linux-doc/") # (find-linuxdocfile "") # (find-linuxdocfile "kernel-parameters.txt.gz") https://askubuntu.com/questions/132965/how-do-i-boot-into-single-user-mode-from-grub http://www.noah.org/wiki/Single_User_Mode *** Select the Kernel line and press 'e' to edit.
