# ticker.sh
> Real-time stock tickers from the command-line.
`ticker.sh` is a simple shell script using the Yahoo Finance API as a data source. It features colored output and is able to display pre- and post-market prices (denoted with `*`).
## Install
```sh
$ curl -o ticker.sh https://raw.githubusercontent.com/pstadler/ticker.sh/master/ticker.sh
```
Make sure to install [jq](https://stedolan.github.io/jq/), a versatile command-line JSON processor.
## Usage
```sh
# Single symbol:
$ ./ticker.sh AAPL
# Multiple symbols:
$ ./ticker.sh AAPL MSFT GOOG BTC-USD
# Read from file:
$ echo "AAPL MSFT GOOG BTC-USD" > ~/.ticker.conf
$ ./ticker.sh $(cat ~/.ticker.conf)
# Use different colors:
$ COLOR_BOLD="\e[38;5;248m" \
COLOR_GREEN="\e[38;5;154m" \
COLOR_RED="\e[38;5;202m" \
./ticker.sh AAPL
# Disable colors:
$ NO_COLOR=1 ./ticker.sh AAPL
# Update every five seconds:
$ watch -n 5 -t -c ./ticker.sh AAPL MSFT GOOG BTC-USD
# Or if `watch` is not available:
$ while true; do clear; ./ticker.sh AAPL MSFT GOOG BTC-USD; sleep 5; done
```
Please note that ticker.sh may require periodic updates of its session with Yahoo Finance. During these instances, the script may take slightly longer to complete.
This script works well with [GeekTool](https://www.tynsoe.org/geektool/) and similar software:
```sh
PATH=/usr/local/bin:$PATH # make sure to include the path where jq is located
~/GitHub/ticker.sh/ticker.sh AAPL MSFT GOOG BTC-USD
```
