## encrypted files; script will create this. Put in a synced folder
ENCRYPTED_FOLDER="~/Dropbox/encrypted"

## mountpoint; script will create this. Should stay empty when not mounted!
## DO NOT PUT THIS IN A SYNCED FOLDER - DOING SO WILL SYNC UNENCRYPTED DATA
MOUNTPOINT="~/.local/cloudmount/Dropbox-Encrypted"

NOTE the cron command scheduler is considered deprecated by Apple, in favor of using Launch Agents along with launchd. There is a decent launchd tutorial at launchd.info if you want to do that instead.

Give cron full disk access

Cron jobs usually need to work outside of the macOS "sandbox", accessing scripts and files across the filesystem. macOS supports Unix filesystem permissions, but there's an additional safety gate that's evaluated

NB: these instructions are for Ubuntu; they work under WSL on Windows 10 as well

Get the decrypt.sh file from here: https://github.com/zhangyoufu/unifi-backup-decrypt

Installation

1. mkdir -p ~/.config && touch ~/.config/ssh-agent.pid
2. Paste the contents of ssh-agent-manage.sh into your .bashrc or .bash_profile or similar
3. killall -9 ssh-agent
4. Start a new terminal session (note: old sessions will not see ssh-agent, only new ones)

Details

This snippet, when included in .bashrc, will ensure that your session has a working ssh-agent with all your ssh keys loaded into it. It does this without creating separate ssh-agent processes by:

Running BurpSuite on a HiDPI display, and that makes the interface window tiny and unreadable?

Just set the _JAVA_OPTIONS environment variable so that it includes -Dsun.java2d.uiScale=2

On Linux, you can edit the BurpSuiteCommunity executable shell script wherever it's been installed, to include the following line near the top (below the #! line, though!):

export _JAVA_OPTIONS="-Dsun.java2d.uiScale=2"
