DATE macro for $TODAY - x-days
I have cases where I need to check if a files exists and sometimes I want to put further actions on that.
Until today I solved it using the system.run command, because it allows to build the file name like this: '*`date "+%Y-%m-%d" -d "31 days ago"`.
But instead of using the system.run command, I would prefer to use the vfs.file.exists command, combined with a trigger action. Trying that, I found that when I try to build the date part of the filename within the vfs.file.exists command like:
vfs.file.exists[my_file_`date "+%Y-%m-%d" -d "31 days ago"`]
then the date command is not executed and thus note replaced with the date.
Does anybody have an idea how this can be solved?
