Full Discussion: How to pass values between awk and shell scripts
Top Forums Shell Programming and Scripting How to pass values between awk and shell scripts Post 302299412 by islegmar on Friday 20th of March 2009 03:55:03 AM

Hi

%% is used for escaping the special character %, so %%s wouldn't expect any command ant it will print the % character.

Code:
sprintf("date -d %s +%%s",d1) 

will print

date -d <value for d1> +%s

which is the command I need for converting the date in format
mm/dd/yyyy in a number (number of seconds) to be able for performing
comparations between dates (which date goes after the oter....)

For example, you can try this code

Code:
awk -v d1=03/20/2009 '
BEGIN { msg=sprintf("date -d %s +%%s",d1);
        print msg;
        system(msg);
      }'

The output will be

Code:
date -d 03/20/2009 +%s
1237503600

So, as it is expected, the probhlem is that I can't capture the value 1237503600 in awk for performing my calculations.

Thanks

Isi
