Description Solène Rapenne 2017-07-10 13:44:35 UTC

Hello,

The output of `date "+%m"` in july is "07". It is possible to remove the leading zero by using the following syntax `date "+%-m"` which will output "7".

I haven't been able to find this in date(1), strftime(3), strptime(3).

I found it by looking gnu date man page and trying it on FreeBSD.

This is documented in strftime(3) which is referenced by date(1):

| %-*   GNU libc extension.  Do not do any padding when performing
|          numerical outputs.
