Full Discussion: awk - change variable on fly
Top Forums UNIX for Dummies Questions & Answers awk - change variable on fly Post 302627121 by haczyk on Friday 20th of April 2012 08:06:59 AM

Using "system" I have error:
Code:
date: extra operand `00:00:00'
Try `date --help' for more information.

But I see where is an issue....Unlucky $10 must be in double qoutas:
#date +%s -d "2008/12/20 00:00:00"
1229727600
# date +%s -d 2008/12/20 00:00:00
date: extra operand `00:00:00'
Try `date --help' for more information.
#

Hm...so how can I surround this variable with double quotas? This is not working:
Code:
awk -v start="$start"  'system("date +%s -d " "$10") < start' file.csv > temp.file

Thank you Jim for hint.
