luckily my login shell is zsh so i can still use the system, and i can still use most of manjaros features and apps, but pacman is’nt working, and neither is yay on snapd. How do get /bin/bash back? will i have to compile it from source or something

this got way more traction than i was expecting, and it is very embarrasing lmao! thanks for everyone who helped solve-!
the solution was

(look in the pacman cache to see if the package containing bash is still present)
`ls -al /var/cache/pacman/pkg/bash*.zst

(then use this to unpack the archive)
tar -xzf /var/cache/pacman/pkg/bash-5.2.026-2-x86_64.pkg.tar.zst

thank you to Nachlese for helping me, and giving me the solution i ended up using,
even though it was supposed to be as easy as “sudo pacman -S bash”

this was a very humbling experience lmao

I presume you mean /bin/bash; Uninstall bash and reinstall it:

sudo pacman -R bash
sudo pacman -S bash

It’s likely that simple. Cheers.

Restore it from your last backup. Simple as that.

Look in the pacman cache whether the package containing it is still there:

ls -al /var/cache/pacman/pkg/bash*.zst

unpack the archive
tar -xvf bash-5.2.026-2-x86_64.pkg.tar.zst

find in resulting structure /usr/bin/bash and copy it where it belongs

It’s easy to do when you boot from USB.
No need to chroot.

i typed /bin/bin by mistake, but when i tried to edit it it gave an error so i gave up

and sadly, pacman doesnt work without bash so that doesnt work :frowning:
neither does yay or snapd or pamac.

but thanks thoughhh!

tar: bash-5.2.026-2-x86_64.pkg.tar.zst: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now

funnily enough, i think unpacking bash may rely on bash :frowning:
thanks for helping thoughh!

Use a zsh shell, perhaps; though from your description you have done more than delete /bin/bash – How did you delete it?

zsh
sudo pacman -R bash
sudo pacman -S bash

Pacman does not rely on bash.

A possible workaround is to install a Terminal emulator that defaults to zsh, via Pamac-Manager (GUI) (Add/Remove Software), and then perform the previous pacman commands.

Yakuaka comes to mind, if you’re using KDE.

You don’t need to be sosmorttt to follow the logic.

and when i deleted it i was trying to delete /usr/bin/ssh because i don’t really have any use for ssh, but out of habit, after typing /bin i switched around ssh and bash :frowning:

about that…

no.
You have the file - but the command to unpack it was without the full path.
Think!

tar -xzf /var/cache/pacman/pkg/bash-5.2.026-2-x86_64.pkg.tar.zst
for example - then you’ll find your bash in /var/cache/pacman/pkg/usr/bin/bash
the command will unpack the file into the current directory - be aware which directory you are in when you run it
I’d copy it to a directory in my $HOME and then unpack it there.

The easiest way is:
cd /
tar -xzf /var/cache/pacman/pkg/bash-5.2.026-2-x86_64.pkg.tar.zst
but this will then replace a lot more, not just /usr/bin/bash

The other possibility is: boot from USB and do it using the tools you know - the graphical file manager

or download the bash install file, or extract what you need from one of the Manjaro mirrors (core) and install it?

Is /usr/bin/bash available?

if yes, you can copy it to /bin/bash

Unfortunately for OP, /bin is installed as a symlink to /usr/bin in Manjaro.

If nothing else works, i guess he can just copy it from a live CD?

/bin is a symlink to /usr/bin

ls -al /bin
lrwxrwxrwx 1 root root 7 Jan 19 19:16 /bin -> usr/bin

bash exists in only one place …

You should NEVER manually remove a file owned by a package. Remove the package using pacman/pamac ONLY IF nothing else depends on it.
