Adding a date as a first column - UNIX for Dummies Questions & Answers

figaro · #1 (**permalink**) 05-20-2008

I want to add a date to a record which is appended to a file that gets its data from an external source. An explanation:

1. Getting external data: curl http://www.example.com/temperatures.txt

2. Getting the required record: | grep mylocation

3. Appending to file: >> mytemperatures.txt

The question is not only to append the temperatures, but to add a column with the current date and time. So I need to add something like "$( date +%Y%m%d%H%M%S )" as the first column to mytemperatures.txt. How is this done?

Thanks in advance

(echo -n `curl http://www.example.com/temperatures.txt | grep mylocation` ; date +param) >> mytemperatures.txt

Thanks, that worked. How do I add a tab character between the columns, notably the grepped data and the date?
