[Gllug] Stories of using filters

[Mick Farmer]

Dear Steve,

One pipeline I've always found useful is analysis of log
files.  You can ring the changes on the one below.  I've
wrapped the lines.

grep PROTO=TCP /var/log/messages* 
     | sed 's/.*SRC=//' 
     | sed 's/ .*//' 
     | sort -n -t. 
     | uniq -c 
     | sort -n

Regards,

Mick               /"\
