Top Forums Shell Programming and Scripting How to tail -f logfile. if log file is generate every 1 HR.? Post 302830927 by Just Ice on Tuesday 9th of July 2013 08:13:30 PM

the tail -F process seems to not let go of the file it was already tailing so creating a new link will not work ... you may need to kill the tail process first prior to creating the new link ...

but if you have to do that, it would be much cleaner and much easier to understand if you tailed the latest file identified by its file name (i.e., CybertonTransaction.20130710-04.log) instead of the generic latest.log ...

Code:
kill -9 $(ps -ef | awk '$0 ~ /tail/ {print $2}')   # <-- assumes only 1 process has "tail" string in command line

tail -f "$(ls -t /usr/home/TF/log/ | head -n 1)"

NAME
mtailrc - Configuration file for monkeytail DESCRIPTION
A monkeytail configuration uses Apache-style syntax to declare "groups" of files to be tailed. Best explained with an example: <group testgroup> prefix 'server2: ' sudo yes <file> filename /var/log/apache2/access.log prefix 'server1: ' host server1.example.com </file> <file> filename /var/log/apache2/access.log host server2.example.com sudo no </file> </group> OPTIONS
All options can be either put inside a group or file block. Options inside a file block override those in the group block. filename filename filename defines the filename for this block. host remote-host (optional) host defines that this block's file is to be tailed on a remote server. sudo yes|no|1|0 sudo is a boolean specifying whether this file should be tailed as root. This option is supported for both local and remote files (in both cases you will potentially be prompted for your password). prefix "string: " prefix allows you to specify a short string that will be prepended to every line that is displayed for that given file.
