Automatically run `shell` command when opening crosh ( CTRL + ATL + T )

[Romuald Brillout]

I extensively use a chroot with crosh.

I therefore keep typing "shell<enter>" throughout the day.

I'd like to automate that and make it that when I open a crosh it automatically runs the `shell` command.

I've been looking for a script that get's executed when a crosh opens but without luck.

Any help would be greatly appreciated

by design, crosh does not allow customization like this.  if you've modified the rootfs, then you could simply change the crosh script itself -- load up /usr/bin/crosh.  you could also do a hack like:

 - cp /usr/bin/crosh /usr/local/bin/

 - edit /usr/local/bin/crosh to do what you want

 - mount --bind /usr/local/bin/crosh /usr/bin/crosh

that mount command will get reset next time you reboot, but you'd only have to run it once, and you could automate it a bit by putting a check in your ~/.bash_profile ... that way the first time you have to type "shell", but subsequent ones you wouldn't have to.

also note that there's tab completion, so typing "sh<tab><enter>" is only 4 keystrokes ;).

changing /usr/bin/crosh did the trick.

Awesome! thanks.

To not make this only a thank post and for future readers;

 - I added `cmd_shell` right before the `repl` call in `/usr/bin/crosh`

 - to make `/usr/bin/crosh` writable;

   - $ sudo /usr/share/vboot/bin/make_dev_ssd.sh --remove_rootfs_verification #eventually add --partitions n

   - reboot

   - $ sudo crossystem dev_boot_signed_only=0

   - $ sudo mount -o remount,rw /

Sorry if the answers to these questions are self-evident but - 

• Is 'cmd_shell' a function you added to 'crosh'?
  
• If so, what is it?

I've done a little work in this area to kick-off a 'crouton' chroot.

Thanx,

Nevermind, found it in 'crosh-dev'...
