Evaluate another awk expression inside awk
In the dataset I am processing, the 5th ($5) column of each line contains a date in '%d/%m/%y' format. I want to compare this with a user provided one.
I know that in order to easily compare dates with relational binary operators they need to be in %y-%m-%d so I need to inline-convert the 5th columns value to that in order for the expression to evaluate to true:
Here's what I've come up with till now:
awk -F "$columnsep" -v dateA="$bornsince" ' awk -F '/' 'print $3"-"$2"-"$1'") ) print' $file
As you can see, the ' awk -F '/' 'print $3"-"$2"-"$1'") ) print' is the expression I am trying to evaluate but I have trouble getting the system call to parse. I really just want to call awk -F '/' 'print $3"-"$2"-"$1'", piping $5 into it in order to convert the date properly.
- Needs to work on macos and linux (ubuntu)
Minimal example dataset:
1099511629352 Nunez Jorge female 17/11/1986
bash awk
