Bash Escaping

Description

I constantly am using watch with some hideous chain of jq and awk.

Perhaps I could always have a dashboard or always have my logs exactly the right info and never need to poll a system for something interesting about it that was unexpected -- yeah, right.

	-- get last item in a list
	myLast [] = error "out of range"
	myLast (x : []) = x
	myLast (_ : r) = myLast r

	main = do
	putStrLn(show(myLast [1,2,3]))

	#!/bin/bash

	set -o pipefail

	SNMPWALK=/usr/bin/snmpwalk
	SNMPGET=/usr/bin/snmpget
	AWK=/bin/awk

	IP=
	MOUNTPOINT="/"

	package main

	import "fmt"
	import "log"
	import "encoding/json"

	import "github.com/aws/aws-sdk-go/aws/session"
	import "github.com/aws/aws-sdk-go/service/s3"

	import "sync"

	#!/bin/sh

	# This kills all mosh-servers not directly the parent of your shell.
	# This will not work entirely correctly if your shell isn't being run directly by
	# `mosh-server`.

	# This next line can either go in your bashrc or the file can be sourced by it.

	alias mosh-clean='(ps jp $$ \|tail -n +2; ps x \|tail -n +2) \| awk '"'"'$1 != skippid && rest && $5 ~ /^mosh-server$/ {print $1} !rest {rest=1; skippid = $1}'"'"' \| xargs -rt kill'

	#!/bin/sh

	# add the following to your .bash_profile
	# PROMPT_COMMAND=". ~/bin/autoactivate;$PROMPT_COMMAND"
	# when you want to work on a project with a venv,
	# run virtualenv venv in the base directory.
	# awesomeness will ensue.

	pushd . > /dev/null

	$ echo "[2,3,4,5]" \| jq -c 'def intersection($a): . - (.-$a); intersection([1,2,3])' │~
	[2,3]

	# Store the notification in a variable. We'll check it later.
	# First, set the variable. We're using "blah".
	- hosts: all
	gather_facts: false
	tasks:
	- set_fact: blah=false

	# Now do some other stuff. Use notify to get the same behavior as a normal handler.
	# Alternatively, just use set_fact with when. They're equivalent.

	def hash_file_by_name(fn):
	hash = hashlib.sha256()
	with open(fn) as f:
	block = f.read(1024*1024)
	hash.update(block)
	return hash.hexdigest()
