As an IT administrator, one of the most important tasks is to make sure that the systems they manage are running at their optimum level and are secure. One way to do this is to be able to identify what operating system is currently running on any given system. Fortunately, there is a way to do this using the Vim text editor, which is a popular text editor used by many IT administrators.
Vim offers a feature called “modelines” which allows users to set specific configuration options depending on the operating system that the file is being opened on. For example, if a file is opened on a Windows system, a certain set of configuration options can be set such as line endings and indentation settings. If the same file is opened on a Linux system, different configuration options can be set.
In order to set these modelines, IT administrators must first identify the operating system that is currently running. This can be done in Vim by using a command called “:version”. When this command is executed, the version information for the current operating system will be displayed. This information can be used to determine what operating system is currently running.
Once the operating system has been identified, the modelines can be set accordingly. To do this, IT administrators must add the following line of code to their Vimrc file:
if &ft =~# \^win\
elseif &ft =~# \^linux\
This code will check to see what operating system is running and then set the appropriate modelines. This can save a lot of time and effort as IT administrators no longer have to manually configure the settings for each operating system.
It is important to note that these modelines will only be applied if the Vimrc file is located in the user’s home directory. If the Vimrc file is located in another directory, the modelines will not be applied.
Overall, using modelines in Vim is a great way for IT administrators to quickly and easily identify what operating system is currently running on any given system. This can save a lot of time and effort as IT administrators no longer have to manually configure the settings for each operating system. Additionally, this feature can be used to ensure that the systems that they manage are running at their optimum level and are secure.
