根據 sudo 訪問避免腳本中的重複程式碼

有沒有辦法減少這裡的重複程式碼？

if have_sudo_access; then
 echo "Installing system wide"
 FONTS_PATH="/usr/share/fonts/.local/share/fonts/"
 sudo mkdir -p "$FONTS_PATH"
 SauceCodePro="https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/SourceCodePro"
 sudo curl -L -o "$FONTS_PATH/Sauce Code Pro Nerd Font Regular.ttf" "$SauceCodePro/Regular/complete/Sauce%20Code%20Pro%20Nerd%20Font%20Complete.ttf"
 sudo curl -L -o "$FONTS_PATH/Sauce Code Pro Nerd Font Bold.ttf" "$SauceCodePro/Bold/complete/Sauce%20Code%20Pro%20Bold%20Nerd%20Font%20Complete.ttf"
 sudo curl -L -o "$FONTS_PATH/Sauce Code Pro Nerd Font Italic.ttf" "$SauceCodePro/Italic/complete/Sauce%20Code%20Pro%20Italic%20Nerd%20Font%20Complete.ttf"
else
 echo "Installing font for local user"
 FONTS_PATH="$HOME/.local/share/fonts/"
 mkdir -p "$FONTS_PATH"
 SauceCodePro="https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/SourceCodePro"
 curl -L -o "$FONTS_PATH/Sauce Code Pro Nerd Font Regular.ttf" "$SauceCodePro/Regular/complete/Sauce%20Code%20Pro%20Nerd%20Font%20Complete.ttf"
 curl -L -o "$FONTS_PATH/Sauce Code Pro Nerd Font Bold.ttf" "$SauceCodePro/Bold/complete/Sauce%20Code%20Pro%20Bold%20Nerd%20Font%20Complete.ttf"
 curl -L -o "$FONTS_PATH/Sauce Code Pro Nerd Font Italic.ttf" "$SauceCodePro/Italic/complete/Sauce%20Code%20Pro%20Italic%20Nerd%20Font%20Complete.ttf"
fi

我曾想過類似的事情：

if have_sudo_access; then
 alias mysudo = "sudo "
else
 alias mysudo = ""
fi

然後對所有需要 sudo 的命令使用 mysudo。

這是一種方法：

#!/bin/bash

## make a temp dir
tmpDir=$(mktemp -d)

## Download the files to it
SauceCodePro="https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/SourceCodePro"
curl -L -o "$tmpDir/Sauce Code Pro Nerd Font Regular.ttf" "$SauceCodePro/Regular/complete/Sauce%20Code%20Pro%20Nerd%20Font%20Complete.ttf"
curl -L -o "$tmpDir/Sauce Code Pro Nerd Font Bold.ttf"    "$SauceCodePro/Bold/complete/Sauce%20Code%20Pro%20Bold%20Nerd%20Font%20Complete.ttf"
curl -L -o "$tmpDir/Sauce Code Pro Nerd Font Italic.ttf"  "$SauceCodePro/Italic/complete/Sauce%20Code%20Pro%20Italic%20Nerd%20Font%20Complete.ttf"

## Check for sudo access using whatever "have_sudo_access" is supposed to be
if have_sudo_access; then
 echo "Installing system wide"
 sudo mkdir -p "/usr/share/fonts/.local/share/fonts/"
 sudo mv "$tmpDir"/* "/usr/share/fonts/.local/share/fonts/"
else
 echo "Installing font for local user"
 mkdir -p "$HOME/.local/share/fonts/"
 mv "$tmpDir"/* "$HOME/.local/share/fonts/"
fi

## delete the now empty tmp dir
rmdir "$tmpDir"
