Change ifinstalled script to exist Renamed ifinstalled to exist, moved it into base shell module. It can be called with just a command name to check for, or with an additional libnotify urgency level (low, normal, critical). If called with an urgency as the second argument, the user will be notified of the missing command with the corresponding urgency. 2020-02-08 19:18:16 +00:00			`#!/usr/bin/env sh`

[sh] Add wording argument to exist script Added optional third argument to exist script which can be used to identify the program or process that needs the command exist looks for. This makes it easier to identify who called exist and is missing something. 2020-05-11 14:52:51 +00:00			`notify-send "📦 $1" --urgency="$2" "must be installed for ${3:-"this"} function."`
