How can I make it work on OSx?

[magnuswikhog]

When running this on OSx, it doesn't export any attachments.

It seems that the regex that extracts the id's doesn't work as expected. When I try running

lpass ls | sed -n "s/^.*id:\s*\([0-9]*\).*$/\1/p"

directly in the terminal, it just returns a bunch of empty lines. I've tried experimenting to get it to work, but didn't succeed.

Any ideas?

Magnus,

I was also unable to get the script to work on Big Sur.

I wrote a stand-alone python 3.7 script as a replacement and managed to get all the attachments.

It's not field tested but I can put it on GitHub if you need it.

Thanks!

However, I already exported my attachments. I ended up just extracting the ID's from lpass ls manually on regexr.com, saved them in a text file and edited the download script, replacing

for id in `lpass ls | sed -n "s/^.*id:\s*\([0-9]*\).*$/\1/p"`; do

with

for id in `cat ../lpass-ids.txt`; do

This works fine for a one-time export, but your Python script might be useful for others who want full automation on OSx.

After some experimenting and a newfound hate of macOS' sed implementation, I got it mostly working by changing line 6 to:

for id in `lpass ls | sed -E -n "s/^.*id:[[:space:]]*([0-9]*).*$/\1/p"`; do

In short: -E is needed for sed on macOS to have even a passing semblance to regex,\s isn't supported even with that, and escaping brackets for match groups is not needed when using -E.

There's still a bug where the saved filenames stop at a space (e.g. "Test File.txt" is saved as "Test"). I just went and manually fixed the filenames by checking the items in Lastpass' Vault.

The script (as currently posted) is not compatible with the macOS (OSX) (Mac OS X) sed, which is from BSD.
The sed from GNU-Linux operates differently.

I fixed it this way:

• [install homebrew from brew.sh]
• brew install gsed
• [find and replace sed with gsed]
• [rerun the script]
