Hi there, and thanks to all of you, how helped me with your tutorials many times. thx falco and others. My first post will evtl. help some of you. Since the last few month pflogsumm http://www.howtoforge.com/mail_statistics_mailgraph_pflogsumm is running beautiful. But sometimes with no Mails in it.? Courios i thougth, searched and see. pflogsumm produced error-message Fund a solution: put -f after gunzip - that force gunzip to overwrite. that helps me. Code: #!/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin gunzip [COLOR="Red"]-f[/COLOR] /var/log/mail.log.0.gz hth Michael P.S. correct posting - or wrong place?
