The ezmaint script attempts to collect various common maintenance tasks that help keep an Arch based system healthy and lean. Below is the menu of the script and the individual functions that perform the actions.

EZArcher Maintenance Script
|
|
-------------------------------------
|
|
|
|
1) Failed systemd services
|
|
2) Check journal logs
|
|
3) Cleanup journal space
|
|
4) Run system update
|
|
5) Clean package cache
|
|
6) Reset all pacman keys
|
|
7) Cleanup user cache folder
|
|
8) Regenerate mirrorlist
|
|
9) Enable Firewalld Service
|
|
|
|
X) Exit
|
|
|
|
Enter your choice:
|
|
|
|
|
|
1. Failed systemd services:
|
|
|
|
systemctl --failed > /tmp/failedsrvs
|
|
nano /tmp/failedsrvs
|
|
|
|
These commands list any failed systemd services and pipe the output into a temporary file that is opened in the nano editor for your viewing. If all output looks OK, closing the nano editor with Ctl+X will return to the main menu. If there are issues, you can copy and paste the suspect lines into a search engine for further review and take appropriate action.
|
|
|
|
2. Check journal logs:
|
|
|
|
journalctl -p 3 -xb > /tmp/journalchk
|
|
nano /tmp/journalchk
|
|
|
|
These commands list any journal entries and pipe the output into a temporary file that is opened in the nano editor for your viewing. If all output looks OK, closing the nano editor with Ctl+X will return to the main menu. If there are issues, you can copy and paste the suspect lines into a search engine for further review and take appropriate action.
|
|
|
|
3. Cleanup journal space:
|
|
|
|
journalctl --vacuum-time=2weeks
|
|
|
|
This command will removed any journal logs older than two weeks and free up space.
|
|
|
|
4. Run system update:
|
|
|
|
pacman -Syu
|
|
|
|
This command will perform a full system upgrade.
|
|
|
|
5. Clean package cache:
|
|
|
|
pacman -Scc
|
|
|
|
This command will perform an aggressive cleaning of the package cache and ask to remove all package cache contents for poth installed and uninstalled packages. If you wish to roll-back packages, this option should not be used.
|
|
|
|
6. Reset all pacman keys:
|
|
|
|
rm /var/lib/pacman/sync/*
|
|
rm -rf /etc/pacman.d/gnupg/*
|
|
pacman-key --init
|
|
pacman-key --populate
|
|
pacman -S --noconfirm archlinux-keyring
|
|
|
|
Thes commands will clear the old GNUPG keyring files and will initialize, populate, and reinstall the archlinux keyring
|
|
|
|
7. Cleanup user cache folder:
|
|
|
|
echo "[Unit]
|
|
Description=Clean primary user cache on boot.
|
|
|
|
[Service]
|
|
Type=simple
|
|
ExecStart=/bin/bash /usr/local/bin/clnusercache.sh
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target" > /usr/lib/systemd/system/clnusercache.service
|
|
|
|
echo "#!/bin/bash
|
|
rm -r /home/*/.cache/*
|
|
rm /etc/systemd/system/multi-user.target.wants/clnusercache.service" > /usr/local/bin/clnusercache.sh
|
|
|
|
chmod +x /usr/local/bin/clnusercache.sh
|
|
|
|
ln -sf /usr/lib/systemd/system/clnusercache.service /etc/systemd/system/multi-user.target.wants/clnusercache.service
|
|
|
|
This option will create a systemd unit to delete all contents of the user's .cache folder upon the next reboot and then remove the systemd. The .cache folder typically contains temporary working files of the desktop and user programs. The contents of the .cache folder can be examined by opening the file manager and viewing hidden files inside the user's home folder in the .cache folder. Please review the files to be deleted before using this option if you are concerned or just curious.
|
|
|
|
8. Regenerate mirrorlist:
|
|
|
|
reflector --latest 10 --sort rate --protocol https --save /etc/pacman.d/mirrorlist
|
|
|
|
This command runs reflector and generates a new mirrorlist file based on the options specified in the command. My defaults are to select the recently updated within the last six hours that are hosted on https servers in the United States. Please look at the man page for reflector if you want to change the options.
|
|
|
|
9. Enable Firewalld Service:
|
|
|
|
systemctl enable firewalld.service
|
|
systemctl start firewalld.service
|
|
|
|
These commands enable and start the Firewalld service.
|

I hope these various functions come in handy. I must give credit to EF Tech Made Simple for his inspiration in the choice and implementation of these functions. Please view his video describing these maintenance tips here: https://youtu.be/wwSkFi3h2nI
