Automating your searches

When you have completed Steps ALPHA and BETA and you have made a search strategy of your own, you should set it up to run daily.  Each day, PubCrawler will compare the new search results to the results from the previous day, and put the new entries onto the results Web page for you to peruse.

1. Open your crontab-file by entering the following command:

crontab -e

2. Set up a schedule for PubCrawler. For example if you enter the following line:

10 07 * * 1-5 "pubcrawler.pl"
PubCrawler would be started at 07:10 hours every weekday (Monday to Friday = days 1-5 of the week.

NOTE: In some cases it might be necessary to include the whole path in the crontab entry like the following:
10 07 * * 1-5 "/home/jsmith/pubcrawler.pl"
Your home directory may be substituted with the variable $HOME:
10 07 * * 1-5 "$HOME/pubcrawler.pl"
If your configuration file could not be found, specify it in your crontab entry with the -c option:
10 07 * * 1-5 "$HOME/pubcrawler.pl" -c "$HOME/pubcrawler.config"

Please make use of NCBI's off peak hours (1am to 1pm GMT)!
