% FUPDATE(1) fupdate 1.0.0
% Benedikt Peetz
% May 2023
# NAME
fupdate - updates your flake, while checking for common mistakes
# SYNOPSIS
**fupdate** list of \[*flake*|*\<some word>*|*--help*|*-h*\]
# DESCRIPTION
Argument can be stacked, this makes it possible to specify multiple targets to be updated in succession. See the Examples section for further details.
No argument or *flake*
: **fupdate**, when executed without arguments or with *flake*, will update your *flake.lock*, check for duplicate flake inputs, i.e., an input has an input declared, which you have also declared as input, and will run a script called *update.sh*, if you allow it.
The allowance for the script is asked, when you run **fupdate** and the found script is not yet allowed. Furthermore, the allowance is based on the concrete sha256 hash of the script, so any changes will require another allowance.
**\<some word>** as argument
: If the executable **update-\<some word>** is reachable thought the PATH variable, than this is run. Otherwise, the program will exit.
# OPTIONS
**--help**, **-h**
: Displays a help message and exit.
**--version**, **-v**
: Displays the software version and exit.
# EXAMPLES
**fupdate** or **fupdate flake**
: Updates your *flake.lock*. See the Description section for further details.
**fupdate sys**
: Run the executable **update-sys**, if it exists. See the Description section for further details.
**fupdate flake sys docs**
: First updates your flake, then, if the command succeeded, runs **update-sys**, afterweich **update-docs** is run.
# FILES
*update.sh*
: This is supposed to be a shell script located in your flake base directory, i.e., the directory which contains both a *flake.nix* and a *flake.lock* file.
*~/.local/share/flake-update/*
: **fupdate** will store the hashes to the allowed *update.sh* files here.
