Nerdfonts in zsh for exa

Leave a comment

After switching to exa as an ls-replacement i also wanted to make use of the nerd-font support ho have icons displayed for files.

alias etree='exa --color --tree --icons=always'

However, in reality the fonts never looked the same in my terminal as in the web preview

So, to easy things up (getting the zip, unzipping it in ~/.local/share/fonts and updateing the fonts-cache) there is a little function which can be placed in the .zshrc/.bashrc to automate things.

#Function to install NerdFonts
function install_nerdfont()
{
	if [ -not $1 ];
	then	
		echo -e "\e[91mParameter missing!\e[0m"
	fi

	cd ~/.local/share/fonts
	wget $1
	unzip -u *.zip
	rm *.zip
	fc-cache -fv	
	cd -

}

Once executed with the download-URL as a paremeter, the font will be installed to your home directory.

If the fonts should be installed system-wide, this can be archived by placing them in /usr/local/share/fonts (folder might needs to be created if it does not exist).

Once the fonts are installed – the terminal-profile must be configured to use the newly installed fonts and that’s it.

Powershell, Windows

Running into “The parameter is incorrect.” / “HRESULT 0x80070057” when managing scheduled tasks via powershell

It took me quite some troubleshooting time, but in the end it’s a quite interessting conclusion.

After trying to create a scheduled task that runs every second Saturday per month, I ran into the following error:

Set-ScheduledTask : The parameter is incorrect.
At C:\ITX\itxWindowsUpdate.ps1:436 char:5
+     Set-ScheduledTask -InputObject $task -User $(Get-LocalUser -Name  ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [Set-ScheduledTask], CimException
    + FullyQualifiedErrorId : HRESULT 0x80070057,Set-ScheduledTask

As Windows Powershell is not able to create monthly tasks I used schtasks.exe utility to create the skeleton for the task/minimal task containing the trigger-definition and afterwards manipulate it via powershell to add the missing configuration.

To do so i used Get-ScheduledTask to obtaint he object references for the task and Set-ScheduledTask to write the object again.

Turns out – the task obtained via Get-ScheduledTask contains the trigger defintion for the montly repetition which can’t be handled by powershell and therefor the task itself can not be saved again but results in the above error. 😜

As it seems there are only two ways on how to deal with that problem:
Export the task-definition as an XML and just reimport it via powershell on other systems which require the same configuration (currently untested) or run it daily and deal with the problem within the script.

Lil bit of the debugging-code as a reference for future projects.
