Old system, need space ...

[dbee]

I have an old computer, that i'm fond of. Mostly cause it's configured with git, wp-env, docker, a microsd card etc... and i don't want to go through the hassle of setting that all up again on a new system

this particular computer only has 30GB hd.

dara@dara-HP-Stream-Laptop-11-y0XX:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
udev            928M     0  928M   0% /dev

/dev/mmcblk0p2   29G   26G  1.5G  95% /

tmpfs           950M     0  950M   0% /sys/fs/cgroup
/dev/mmcblk0p1  511M  8.5M  503M   2% /boot/efi
tmpfs           190M   28K  190M   1% /run/user/1000
/dev/mmcblk1    115G   61M  109G   1% /media/dara/microsd

I have only 1.5GB left on the system. I'm already pruning docker on boot.

$ crontab -l
@reboot rm -rf /home/dara/wp-env/*
@reboot docker system prune -a

I'm on bionic xubuntu...

dara@dara-HP-Stream-Laptop-11-y0XX:~$ lsb_release -a

I've installed my last update. The latest one was 130MB. I'm assuming that's the compressed size. I'll probably be foregoing updates for the considerable future. At least until i can get my external hd working with the system...

I don't suppose you can install updates/upgrades on external hds by any chance?

Anyway, my question is this. I have a large journaled '/var/log' file that I'm not using. How can i remove it and cut back on the logging feature?

I delete older logs with this in my housecleaning script.
sudo find /var/log/ -name *.gz* -type f -atime +10 -print -exec rm -f {} +

I also houseclean Firefox & Thunderbird cache2.

Excellent thanks oldfred.

any idea on how i can store that command in my emacs/shell env?

So i can run it like ...

$ $my_command

[oldfred]

I have my own script which is something like this:
I check sizes, update & houseclean in one script.
