| Welcome to crosh, the ChromeOS developer shell. |
In dev mode chromeos, most mounts are noexec except /usr/local so that is why executeables are in /usr/local/bin Almost everything in my /usr/local was installed by chromebrew (crew) except a few items I manually copied to /usr/local/bin
As a way to tag items I manually added, I change the group from chronos to some other group and I chose midis which seems safe. So for example, I like to keep a non-executeable list of what crew has installed in /usr/local/bin
crew list installed > /usr/local/bin/crew-list-installed.txt
I also sometimes manually install in /usr/local/bin some *.sh or a few binaries crew does not (yet) provide, like btm.
Better than forked gist here is Alternative method below...
#!/bin/bash
URLs=$(curl "https://dl.google.com/dl/edgedl/chromeos/recovery/cloudready_recovery2.json" \
-s --output - | \
grep "^.*\"url\".*$" | \
sed "s/.*\"url\": \"\(.*\)\".*$/\1/g")
printf "\nPick which channel to download your image from. Channel name is near the end of the URL.\n\n"
