Delete a row from a file if one column containing a date is greater than the current system date
Hello gurus,
I am hoping someone can help me with the required code/script to make this work. I have the following file with records starting at line 4:
Logic would be:
1. Start reading line @ Row 4.
2. Check the date of the last column.
3. If date > current date, delete line
3. If there is no date, retain line
So from the example above, the record in the middle should be deleted from the file, thus retaining the 1st and 3rd lines.
Much appreciated!

tartdates - Special date configuration for LinuxTaRT
DESCRIPTION
LinuxTaRT uses a configuration file called specialdates to enable the user to display a specific tagline on certain special dates. The name
and location of this file is specified in the LinuxTaRT configuration file ~/.tartrc, but is usually:
~/.tartdates
PARAMETERS
Each line of the special date file consists of a day of the year expressed as a two digit month, a forward-slash (/), a two digit date, a
colon (:) and a line of text.
mm/dd:tagline text
Any line that does not conform to this specification will be treated as a comment. Comments may also be specified by prefixing text with a
# symbol. Using this method, you can place a comment behind a date line.
EXAMPLES
01/01:Happy New Year!!
Will use "Happy New Year!!" as the tagline when the date is January 1st.
