Awk strftime on Mac OS X

awk, bash, macos

Solution

strftime is a GNU gawk extension. If you want to use strftime, download GNU gawk and install on your Mac. Otherwise, there are other tools like Perl/Python you can use. Check if you have them on your Mac

Problem

The following command on my Mac (10.6) gives me an undefined function error: ``` $ awk 'BEGIN{now=strftime("%D", systime()); print now}' awk: calling undefined function strftime source line number 1 ``` On a Red Hat system, I get the expected result: ``` $ awk 'BEGIN{now=strftime("%D", systime()); print now}' 12/01/09 ``` What's the deal here?
