Hi, Voytek: > I would like to fetch date/time from html file, and use date comparison > and make an ics/vcal file eventually Hmm, sounds like you might want to use a different programming language, like python, perl or something, rather than just a shell script. It can be done in shell script, but it'll be advanced shell scripting, while it would be fairly basic python or perl or whatever. > the date comes as so: > <tr><td colspan="1" rowspan="1">Start Date Time: </td><td colspan="1" > rowspan="1">20/03/2014 1400 Thursday</td></tr> > is 'grep -o' the way to go ? what regex do I need where I put ???? ? You might want to use "grep" first to get the correct lines out, so you're not doing multiple things in one command, then either grep -o to get the date out, or the cut command. Something like: grep 'Start Date Time' | cut -d '>' -f5 | cut -d '<' -f1 > what do I need to do with date to be able to compare it to a date range? You have two options here: * convert it to an integer, with the date command (date -d $x +%s), then work with them as integer number of seconds, or * touch a temporary file, again with the -d option, then check which file is older.
