xe.com

Environment

You can set variable XE_CCCY_FROM and XE_CCY_TO in order to define your default from/to pair. Add this to your .bashrc to have default pair EUR/USD:

export XE_CCY_FROM=EUR
export XE_CCY_TO=USD

Examples

xe.com -f USD -t GBP -d 2021-03-17

# will return the XE.COM close rate for USD/GBP pair on 17 Mar 2021

xe.com usd gbp 2021-03-17

# the same, but shorter

xe.com -d 2021-03-17

# the same, but for the default pair (RUB/USD)

xe.com 2021-03-17

# the same in the shortest form possible

xe.com 21.03.17

# you can do this too, but I am not guessing whether this is YY.MM.DD or DD.MM.YY -- use at your own risk

xe.com -s FROM TO DATE

# this form allows chaining with the likes of bc(1) to make calculations, e.g. echo "$(~/bin/xe.com -s rub eur 20220510)*1234.56" | bc

xe.com rub eur 20220510 1234.56

# will convert from RUB amount of 1234.56 to EUR with a rate as of 10 May 2022
