hilbix / kswapd-check.sh
Created March 28, 2013 15:27
Bash/AWK script to detect 100% CPU on kswapd processes, caused by a known Linux kernel issue on RHEL 5.5 (and CentOS) kernel 2.6.18-194.el5. Returns 0 if no problem, and usually 2 when the problem hits. (Note: It will return 1 on first invocation. Better safe than sorry.)

hilbix / GIT branch relation aliases
Last active December 29, 2015 17:19
GIT "relate" ALIAS to quickly show how all branches relate to HEAD (or given branch). GIT "graph" ALIAS to show the graph between two commits (from HEAD to it origin, or given branch, by default). `graph` Improved to highlight starting point (which is not always obvious).
git config --global --replace-all alias.relate '!f(){ git for-each-ref --format="%(refname:short) %(upstream:short)" refs | while read -r l r; do printf "%24s %s\\n" "$(git rev-list --cherry-mark --dense --left-right --boundary --oneline "${r:-${1:-HEAD}}...$l" -- | sed "s/^\\(.\\).*/\\1/" | sort | uniq -c | tr -d " " | tr "\\n" " ")" "$l"; done; }; f'
git config --global --replace-all alias.graph '!f(){ case "$#:$1" in 0:) r="HEAD...HEAD@{u}";; 1:*...*) r="$1";; 1:*) r="HEAD...$1";; *) r="$1...$2";; esac; git rev-list --cherry-mark --dense --left-right --boundary --pretty --graph "$r" -- | less -XFp "$(git rev-parse "${r%...*}")"; }; f'

hilbix / exec style aliases
Last active March 10, 2019 01:21
`git exec` to exec command within GIT directory. `git top` to exec on submodule top level directory (somewhat).
git config --global alias.exec '!exec '
git config --global alias.top '!f() { GIT_TOP="${GIT_DIR%%/.git/modules/*}"; [ ".$GIT_TOP" != ".$GIT_DIR" ] && cd "$GIT_TOP"; exec "$@"; }; f'
# THIS IS PUBLIC DOMAIN.
#
# `git exec` executes something in the current GIT module's base directory. `git exec pwd` gives this base.
# Stolen from http://stackoverflow.com/questions/957928/is-there-a-way-to-get-the-git-root-directory-in-one-command/957978#comment9747528_957978
#
# `git top` is like `git exec`, but executes in the topmost GIT directory, even from within a GIT submodule.
