Bash-Snippets: A collection of small bash scripts for heavy terminal users

I'd just drop the ping to google entirely. If wget/curl/fetch fail, so be it. No need to introduce additional slowness for the small chance internet isn't working.

  # Encrypt a file
  function encrypt() { openssl enc -aes-256-cbc -salt -a -in $1 -out $2 ; }

  # Decrypt a file
  function decrypt() { openssl enc -aes-256-cbc -d -a -in $1 -out $2 ; }

  # Fetch weather forecast
  function weather() { curl "http://wttr.in/$1"; }

  # Convert input text into a QR code
  function qrify() { curl "http://qrenco.de/$1"; }

  # Fetch information about a stock
  function stock() { curl -s "https://www.alphavantage.co/query?function=GLOBAL_QUOTE&symbol=AAPL&apikey=KPCCCRJVMOGN9L6T" | awk '/\. / {$1=""; gsub("\"|,",""); print $0}'; }

  # Conversion rate between currencies
  function currency { curl -s "http://api.fixer.io/latest?base=$1&symbols=$2" | grep -Eo "[0-9]*[.][0-9]*"; }

  # Fetch movie info
  function movie { curl -s "http://www.omdbapi.com/?t=${1/ /+}&apikey=946f500a" | jq ". | {Title, Year, Ratings:[.Ratings[1].Source, .Ratings[1].Value ], Rated, Genre, Director, Actors, Plot}" | awk -F "\"" '/:|%|Tomato/ {print $2 $3 $4}' | sed '/: \[/d' | perl  -pe 's/,\n/: /'; }

  # Fetch cheatsheet
  function cheat() { curl "http://cheat.sh/$1"; }

  # Fetches DNS nameserver ???
  function dns_nameserver() { cat /etc/resolv.conf | grep -i ^nameserver | cut -d ' ' -f2; }

  # Fetches WAN ip address ???
  function wan_search() { dig +short myip.opendns.com @resolver1.opendns.com ; }

  # Show actual destinatoin of a tinyurl. Eg: untiny "tinyurl.com/savepii"
  function untiny() { curl -s "http://x.datasig.io/short?url=http://$1" | awk -F '"' '/d

And for Pandora, there is Pianobar, a console based pandora player: https://github.com/PromyLOPh/pianobar

EDIT: ...oh, it sends your data to a public service, which is not what I would prefer. But the cleverness of the service (rendering the pixels via ASCII) seems like it would make a great local utility.

Another EDIT: the encoding lib is LGPL, support for ASCII rendering contributed by Ralf Ertzinger -- https://github.com/fukuchi/libqrencode

Until then I had used bash exclusively for years. Now I will absolutely never go back.

  # Encrypt a file
  encrypt() { openssl enc -aes-256-cbc -salt -a -in $1 -out $2; }

  # Decrypt a file
  decrypt() { openssl enc -aes-256-cbc -d -a -in $1 -out $2; }

  # Fetch weather forecast
  weather() { curl "http://wttr.in/$1"; }

  # Convert input text into a QR code
  qrify() { curl "http://qrenco.de/$1"; }

  # Fetch information about a stock
  stock() { curl -s "https://www.alphavantage.co/query?function=GLOBAL_QUOTE&symbol=$1&apikey=KPCCCRJVMOGN9L6T" | awk '/\. / {$1=""; gsub("\"|,",""); print $0}'; }

  # Conversion rate between currencies
  currency() { curl -s "http://api.fixer.io/latest?base=${1^^}&symbols=${2^^}" | grep -Eo "[0-9]*[.][0-9]*"; }

  # Fetch cheatsheet
  cheat() { curl "http://cheat.sh/$1"; }

  # Fetches DNS nameserver
  dns_nameserver() { awk '/nameserver/ {print $2}' /etc/resolv.conf; }

  # Fetches WAN ip address
  wan_search() { dig +short myip.opendns.com @resolver1.opendns.com; }

  # Show actual destination of a tinyurl. Eg: untiny "tinyurl.com/savepii"
  untiny() { curl -s "http://x.datasig.io/short?url=http://$1" | awk -F '"' '/dest/ {print $4}'; }

  # Get your remote IP addr
  myip() { curl -s http://x.datasig.io/me | awk -F"\"" '/ip/ {print $4}'; }

  # Fetch movie info
  movie() { curl -s "http://www.omdbapi.com/?t=${1/ /+}&apikey=946f500a" | jq ". | {Ratings:[.Ratings[1].Source, .Ratings[1].Value ], Plot, Actors, Director, Genre, Rated, Year, Title}" | sed -e '/Ratings/{N;N;N;s/\n/ /g;s/"Ratings": \[     //;s/,    /:/;s/   ]//}' | awk -F'"' '/: / {print $2 ": " $4}'; }

(Note: it's mostly an educational tool; for example, you could enable an option to make climate print the actual command before executing so that you can learn your way around using the shell effectively.)

The most beloved bash script collection S2

I've been keeping my bash scrips in github gists but I like this organization as well.

:(

I would be curious to know why - if it's just bash, Cygwin has great support for it.

  $ llbin | nlines
  738

But there are some tools which are compute related and I'd recommend everyone try once:

1) cheat. Total lifesaver. I used to backup my histories but I no longer do so since most commands I use have an example there.

2) qrify looks good, not sure how often i'll use.

About crypt: I'd suggest installing openssl and using tools in there. Crypto is hard to get right, not to dissuade anyone from trying to create but as an end user, always use something widely used.
