I have a shell script and I need to run it in order to connect to a remote ubuntu linux machine having encrypted HDD, in order to enter the passphrase. There's a shell script for this, but I have a chromebook most of the time when away. Can this be done from a chromebook?

I have already seen chrome extensions like mosh.

The shell prompt is available in Chrome OS. The instructions for accessing it are available here: https://chromium.googlesource.com/chromiumos/docs/+/master/developer_mode.md.

If the script happens to be stored on a filesystem mounted with noexec (such as your home directory), then the script may need to be called with sh explicitly:

/bin/sh foo.sh

More information: In Chrome OS, Bash won't execute my script. How do I get Bash to run my script?.

1. Enable developer mode
  • Holding Esc + Refresh(F3) + pressing Power button --> release Power Button. This is recovery mode
  • inside recovery mode, press Ctrl + D. this turns on developer mode
2. Get the Command Prompt
  • either with:
    • Ctrl + Alt + →[ right-arrow ]
    • Ctrl + Alt + T
3. Remount folder with exec permission

For system security reasons on ChromeOS certain folders are marked no-exec so remount with:

sudo mount -i -o remount,exec /home/chronos/user/
  • this step is usually what let you run bash scripts, exec programs you installed like meteor. Also, could be for external devices:
$ sudo mount -o remount,exec /media/removable/SD\ Card
$ sudo mount -o remount,exec /media/removable/USB\ Drive
  • noexec will disappear from the mount options when you query.
