# apt-upgrades
|
|
|
|
Show the number of pending system upgrades, as reported by aptitude.
|
|
More specifically, show: packages upgraded, newly installed, to remove, and not upgraded.
|
|
|
|
|
|
|
|
|
|
# Requirements
|
|
|
|
Dependencies: aptitude, bash
|
|
|
|
Suggested: fonts-font-awesome
|
|
|
|
# Suggested usage
|
|
|
|
Copy the `i3blocks.conf` section into your i3blocks configuration.
|
|
We assume you use `signal=1` but you can choose another signal number if you prefer.
|
|
Create apt/dpkg hooks to signal the script.
|
|
For example, create `/etc/apt/apt.conf.d/80i3blocks` with contents
|
|
|
|
```
|
|
APT::Update::Post-Invoke { "pkill -RTMIN+1 i3blocks || true"; };
|
|
DPkg::Post-Invoke { "pkill -RTMIN+1 i3blocks || true"; };
|
|
```
|
|
**Warning**: make sure to
|
|
```ShellSession
|
|
sudo chown root:root /etc/apt/apt.conf.d/80i3blocks
|
|
sudo chmod 644 /etc/apt/apt.conf.d/80i3blocks
|
|
```
|
|
so that only the root user may modify
|
|
`80i3blocks`. This is necessary because apt has root privileges when upgrading the system,
|
|
and therefore commands in `80i3blocks` will be executed with root privileges.
|
|
|
|
You may also combine this script with a cron job that calls `apt-get update` periodically for
|
|
a more "popup upgrade reminder" feeling.
|
|
|
|
# Simple usage
|
|
|
|
Instead of using `signal=1` in the configuration, you can use `interval=3600`
|
|
to have the script execute every hour.
|
|
This method avoids the usage of apt/dpkg hooks.
|
|
|
|
# Config
|
|
|
|
```INI
|
|
[apt-upgrades]
|
|
command=$SCRIPT_DIR/apt-upgrades
|
|
signal=1
|
|
interval=once
|
|
#PENDING_SYMBOL="\uf021 "

#SYMBOL_ONLY=0
|
|
#ALWAYS_PRINT=1

#PENDING_COLOR="#00FF00"
|

#NONPENDING_COLOR="#FFFFFF"
