705,857 | I want to do some calendar manipulations in bash - specifically, I want to figure out the last date of a given month (including leap-year, and a preparing a table for a lookup is not a valid solution for me).
Supposedly I have the following code:

Intuitive I know. Earlier versions of date used to work the POSIX way. | If you don't mind playing with grep/awk/perl, you can take a look at `cal`.
```

45,826,243 | I have a table in SAS where in one column, the date is stored (e.g. "2005/10").
How do I have to convert this to a SAS data format?
Among many other tries, I tried this code:
data test;
```
format date YYMMS.;
date = input(ObservationMonth, YYMMS.);
put date=date9.;
run;

] | One way is to use `substr()` and `mdy()` to extract the date components:
```
data _null_;
ObservationMonth ="2005/10";
date =mdy(substr(ObservationMonth,6,2),1,substr(ObservationMonth,1,4));
put date = date9.;
run;
```
Another option is to use the `anydtdte` informat (note that results may differ depending on ... | you're fantastic, guys! Thank you so much, with a "set" statement it works fine! |
