I need a bash, sed, awk script or one liner to do the following task:
This is the format of a text file:
I need to delete from this file the lines where the date and time in the first two columns are older then a given date.
I think may be a good solution to replace the date and time with the format of date in seconds since 1970-01-01 00:00:00.
This command is working, but I don't know how to replace the output in place.
After that may be using some kind of conditional grep...
- I know, this command isn't exist, just an example...
Thank you in advance,
vazi
