which referenced back to a podcast upon which I appeared in 2010 ….
This was all about using a 3rd party binary to allow me to view multiple log files in a single window ...
And yet, last week, I noticed a client using the stock version of tail to achieve precisely the same outcome.
So, whereas I was reduced to doing this ( without Multitail ): -
tail -f /opt/ibm/WebSphereProfiles/AppSrv01/logs/AppClusterMember1/SystemOut.log
tail -f /opt/ibm/WebSphereProfiles/AppSrv01/logs/SupClusterMember1/SystemOut.log
tail -f /opt/ibm/WebSphereProfiles/AppSrv01/logs/MEClusterMember1/SystemOut.log
tail -f /opt/ibm/WebSphereProfiles/AppSrv01/logs/SupClusterMember1/SystemOut.log
tail -f /opt/ibm/WebSphereProfiles/AppSrv01/logs/MEClusterMember1/SystemOut.log
I realised that I can do this: -
tail -f /opt/ibm/WebSphereProfiles/AppSrv01/logs/AppClusterMember1/SystemOut.log /opt/ibm/WebSphereProfiles/AppSrv01/logs/SupClusterMember1/SystemOut.log /opt/ibm/WebSphereProfiles/AppSrv01/logs/MEClusterMember1/SystemOut.log
and see this: -
