sed on FreeBSD file listing

sed can be used to modify a FreeBSD file listing with regular expressions, allowing you to convert an ls into a csv, for example.

Given a file listing like:

-rwxr-xr-x   1 Andrew.Potts  wheel   7417965 Apr 12  2023 Yoi.MOV

-rwxr-xr-x   1 Andrew.Potts  wheel  13536345 Apr 12  2023 Yondan Hands.mp4

-rwxr-xr-x   1 Andrew.Potts  wheel  11488336 Apr 12  2023 Zuki.mp4

You can create and test the regular expressions on Sed Tester: https://sed.js.org/

Note however, early versions of FreeBSD don't support characters like \s, \S or \d.
Instea you must use commands like [:alpha:]

ls -la | sed -E 's/^([-drwx\+]*)[[:space:]]+([0-9]+)[[:space:]]+([[:alpha:].]+)[[:space:]]+([[:alpha:]]+)[[:space:]]+([[:digit:]]+)[[:space:]]+([[:alpha:]]+[[:space:]]+[[:digit:]]+[[:space:]]+[[:digit:]]+)[[:space:]]+(.+)$/\7,\5,\6/p'

's/\(.* [A-Za-z]* [0-9]*\) \([0-9]*\) \([a-z|A-Z]* [0-9]* [0-9]*:[0-9]*\) \(.*\)/\4,\2,\3/'

 ls -la | sed -E 's/^([-drwx\+]*)[[:space:]]+([0-9]+)[[:space:]]+([[:alpha:].]+)(.+)$/\3/p'

Capture 

([-rwx]*)\s+(\d+)\s+(\S+)\s+(\S+)\s+(\d+)\s+(\w+\s+\d+\s+\d+)\s+(.+)$

--regexp-extended --expression='s/^([-rwx]*)\s+([0-9]+)\s+(\S+)\s+(\S+)\s+([0-9]+)\s+(\S+\s+[0-9]+\s+[0-9]+)\s+(.+)$/\5,\6,\7/'

Outlook PWA opens email links in Edge

 I prefer Outlook Personal Web App (PWA) over the thick client.

The problem I was having was that clicking on a http link within an email opened Edge rather than my default Chrome.

I double-checked the default App settings in Windows 11 and everything was set to Chrome.

Sadly, the instructions for setting the browser in the Outlook thick client application do not apply to the Personal Web App. Even though you set it to "use the default browser" that setting is not respected in the PWA, nor can you set it in the PWA.

The solution is to actually set the PWA as a Chrome app, not an edge app. 

In Chrome, navigate to https://outlook.office.com/mail/.
The button to install it as a PWA is on the search bar. Click on that.

Mounting an external FAT32 USB drive with FreeNAS

Mount the FAT32 disk

dmesg | grep da1

mkdir /mnt/usbhdd

mount_msdosfs -o large /dev/da1s1/ /mnt/usbhdd

rsync -recursive --ignore-existing --human-readable --progress "/mnt/usbhdd/Matthew Potts iPhone 12 Photo Backup/" "/mnt/Data/My Media/Matthew/Photo Backup/"

To copy a file pattern:

rsync --include='**/*.MOV' -recursive --ignore-existing --human-readable --progress "/mnt/usbhdd/Matthew Potts iPhone 12 Photo Backup/" "/mnt/Data/My Media/Matthew/Photo Backup/"

To count files:

find . -maxdepth 1 -type f -print | wc -l

ASP.NET Development Certificates in Traefik

The ASP.NET Core HTTPS development certificate can be created with the dotnet dev-certs command.

It is found in Certificate Manager (User Certificates, NOT Local Computer) under the Personal Certificates and Trusted Root Certification Authorities nodes.

You can search for it by it's SHA-1 hash (known as the thumbprint in the Certificate Details tab).

To export the certificate for use in a Traefik Reverse Proxy, type:

dotnet dev-certs https --export-path aspnet.crt --trust --format Pem --no-password

and follow these instructions to add it to Traefik:
