[Logcheck-devel] removing empty lines

[Thomas E. Horner]

Hi list,

when rebooting my ubuntu server usually generates a logcheck email that 
looks as if it was empty because it contains a *lot* of empty lines on 
top. Usually - at least for me - empty lines are not of any help so i 
feel those empty lines should be removed.

Please find the following diff that i think should be integrated into 
logcheck:


root at www:/usr/sbin# diff -u logcheck.org logcheck
--- logcheck.org    2015-10-01 06:33:09.331932123 +0200

   # First sort the logs to remove duplicate lines (from different 
logfiles with
   # the same lines) and reduce CPU and memory usage afterwards.

'/^$/d' | cat  \
       > "$TMPDIR/logoutput-sorted" \
           || error "Could not output to $TMPDIR/logoutput-sorted."


Br,
