Scheduling LinkScan on Unix Systems

The following example is provided to assist those users who wish to run LinkScan as a cron job. The crontab system is a standard Unix utility that enables jobs to be executed automatically according to some regular schedule. On most Unix systems, see man crontab or man 5 crontab for help.

  1. Save any existing configured cron jobs to a file (for example, cron.job) using the following shell command:

    crontab -l > cron.job
    
  2. Edit the file cron.job and append an additional entry for LinkScan containing something like:

    40 8 * * 0,1,2,3,4,5,6 /usr/linkscan/linkscan.cron
    

    This will execute /usr/linkscan/linkscan.cron at 08:40am each day. Adjust the pathname to linkscan.cron accordingly.

  3. Submit this to the crontab system with the following shell command:

    crontab cron.job
    

    You can check that it's been scheduled with:

    crontab -l
    
  4. Edit the linkscan.cron file -- the following example file is automatically installed in the LinkScan directory:

    #!/bin/sh
    
    # Set current working directory
    cd /usr/linkscan/
    
    # Execute LinkScan
    /usr/local/bin/perl linkscan.pl -project proja
    /usr/local/bin/perl linkscan.pl -project projb
    
    # Execute LinkScan/Dispatch (if required)
    /usr/local/bin/perl dispatch.pl -project proja -options
    
    # Execute command line reports (if required)
    # Must set environnment variable for these
    # setenv linkscan linkscan
    export linkscan=linkscan
    /usr/local/bin/perl linkscan.cgi -project proja -options
    

    See the following for a summary of the available command line switches/options:
