Modify /etc/inputrc on read-only file system

filippobistaffa · July 26, 2021 at 12:15 PM

I am trying to modify the file /etc/inputrc in order to enable some auto-complete features to my terminal, but it seems that the entire file system is mounted as read-only.

What's the easiest way to modify that file?

From man readline:

Code

INITIALIZATION FILE
       Readline  is  customized  by putting commands in an initialization file
       (the inputrc file).  The name of this file is taken from the  value  of
       the  INPUTRC  environment  variable.   If  that  variable is unset, the
       default is ~/.inputrc.  If that file  does not exist or cannot be read,
       the  ultimate  default  is /etc/inputrc.

I already tried to create a file named .inputrc in my home directory containing the following lines:

Code

"\e[A": history-search-backward
"\e[B": history-search-forward

But this doesn't seem to work...

busybox's ash is not using readline.

So? Is there any way to make this work?

No.

Would this be possible by switching to /bin/bash instead of /bin/sh?

/bin/bash and /bin/sh are both linked to busybox's ash, there is no difference.
