Hi Guys,
when installing an application, I believe there is a log file which is create to log the progress of the installation.
What I will like to know is, how do you tail the start log file to see the installation as it is progressing.
I will really appreciate your help.
Thanks
You'll have to find the name of the log file the application or your system application installer uses first. Once you have that name, you can use the command:
to follow new data being added to the end of the file. If it is a long running install with infrequent writes to the log file, you want to continue using the terminal window to run other stuff while the installation is proceeding, and don't mind having to refresh you screen if a log file update overwrites something from the command you're currently running in the foreground, you can add an ampersand (&) to the end of the tail command to put it in the background. (If you do this, don't forget to kill the tail after the installation completes.)
