When I was building the environment, I accidentally deleted /bin/ and had no choice but to obtain the same coreutils as the installed version, and copied the bin folder and below to /bin/.
Until now, the terminal was started, but when I tried to start the terminal, it didn't start, and when I selected xterm, it said, "Could not exec/bin/sh There are no such files or directories" and it stopped starting.
The environment was built in Ubuntu 18.04, and prior to removing /bin as an associated operation:
$sudodpkg-reconfigure dash [select no]
$ sudorm/bin/sh
$ sudorn-s/bin/bash/bin/sh
I apologize for the lack of study, but could you tell me how to solve this problem or the reference site?
ubuntu bash terminal dash
What's in the Ubuntu packageThe results are as follows
coreutils contains some /bin/ commands, but bash requires the bash package to work.(Other shell packages)
You will get it and deploy it below /bin/ (like coreutils).
