I'm having a pretty big issue that I need to get resolved. Basically I have little experience using Linux and I've been working on a project recentley that involves me having to use quite a lot of Linux commands to run php scripts on my web server.Basically I've two scriptsget_tweets.phpparse_tweets.phpI need these to be running constantly for the next 3 - 4 weeks on my web server. I use the following command to get them to run and they seem to last for the day but when I check in the morning they seem to have stopped working!nohup php get_tweets.php > /dev/null & and thennohup php parse_tweets.php > /dev/null & I know that by using & I can keep the scripts running in the background and they run when I log out of ssh but like I said they seem to run fine all day then when I check in the morning they've stopped. The issue I am having is how I can keep them running non stop. Is there a simple script I could write to check if they are running and if not then restart them or perhaps restart them every 5 hours or something?I'd appreciate any help guys as this is quite a big issue and I've got no idea how to resolve it.
