date manipulation

[Andrej Vavro]

Hi,

how can I find last month name in bash script? Best would be in %b format.

Regards,
Andrej

maybe I didn't understand you're question (my english isn't so good :-), but could you explain 'last month name'?

the date command can print dates in any way you like. man page helps a lot

"Last month"="current month"-1

Colud you please provide more details about syntax in bash?

lastmonth = current - 1

I need just syntax. +1, -30 doesn't work in echo. I need just syntax.

Thanks
Andrej

this seems to work:

$ date date --date="last month" +"%b"

Hi,

the idea was something like this.

$let last_month=$(date +%m)-1
$echo $last_month
