Hi, We all know the use of programs like "cat" or "tail" to show file contents. I have a cluster of apache and each httpd logs to /var/log/httpd/access.log where /var/log is a link to a gfs filesystem [root@apache1]# ls -la /var/log/httpd lrwxrwxrwx 1 root root 20 27 feb 15:44 /var/log/httpd -> /gfsvolume/log/httpd_local/@hostname For each apache I have a directory, like /gfsvolume/log/httpd_local/apache1 /gfsvolume/log/httpd_local/apache2 I'd like to show on screen, like with a cat program, all access.log files reading them from each directory in cronological order. Is there an already made program to do this? I need something as follow: If /gfsvolume/log/httpd_local/apache1/access.log contains something like the following: 127.0.0.1 - - [14/Mar/2006:13:27:26 +0100] "GET /ocsinventory/deploy/label HTTP/1.0" 500 616 "-" "NSISDL/1.2" 192.168.26.163 - - [14/Mar/2006:13:27:41 +0100] "POST /ocsinventory HTTP/1.1" 200 83 "-" "OCS-NG_windows_client_v4014" And /gfsvolume/log/httpd_local/apache2.comune.prato.it/access.log contains something like the following: 192.168.26.163 - - [14/Mar/2006:13:27:23 +0100] "GET /ocsinventory/deploy/label HTTP/1.0" 500 616 "-" "NSISDL/1.2" 192.168.1.110 - - [14/Mar/2006:13:27:42 +0100] "GET /ocsinventory/deploy/ocsagent.exe HTTP/1.0" 500 616 "-" "NSISDL/1.2" With "multicat" (the program I am looking for, just invented a name to refer to it) multicat /var/log/httpd/acces.log I obtain the following: 192.168.26.163 - - [14/Mar/2006:13:27:23 +0100] "GET /ocsinventory/deploy/label HTTP/1.0" 500 616 "-" "NSISDL/1.2" 127.0.0.1 - - [14/Mar/2006:13:27:26 +0100] "GET /ocsinventory/deploy/label HTTP/1.0" 500 616 "-" "NSISDL/1.2" 192.168.26.163 - - [14/Mar/2006:13:27:41 +0100] "POST /ocsinventory HTTP/1.1" 200 83 "-" "OCS-NG_windows_client_v4014" 192.168.1.110 - - [14/Mar/2006:13:27:42 +0100] "GET /ocsinventory/deploy/ocsagent.exe HTTP/1.0" 500 616 "-" "NSISDL/1.2" I understand there be some configuration file that map /var/log/httpd/access.log to /gfsvolume/log/httpd_local/apache1/access.log /gfsvolume/log/httpd_local/apache2/access.log And inform the program about the format and the position of the sorting key.
