[Bug]: can't change shell to zsh
Problem description
Can't change shell to zsh
Steps to reproduce the behavior.
chsh -s $(which zsh) /data/data/com.termux/files/usr/bin//data/data/com.termux/files/usr/bin/zsh is not an executable file!
What is the expected behavior?
No response
System information
- Termux application version:
- Android OS version: 15
- Device model: pixel 7 POS
- zsh --version zsh 5.9 (aarch64-unknown-linux-android)
This also DOES NOT WORK:
chsh -s zsh
It executes without error but does nothing. Please help me get out of 1990s bash hell
As a workaround, you can call chsh without arguments and then type zsh at the prompt.
zsh only shows up when logging in via ssh.
Did you guys really hard code bash into termux?
We did not hardcode bash into Termux. It's just the default shell.
chsh -s zsh followed by restarting Termux works just fine on my device.
The user's shell is determined via ~/.termux/shell in Termux
// ~% ls -l ~/.termux/shell
lrwxrwxrwx. 1 u0_a215 u0_a215 39 Apr 8 02:02 /data/data/com.termux/files/home/.termux/shell -> /data/data/com.termux/files/usr/bin/zsh
Please verify that it is correctly pointing at Zsh.
Also make sure your packages are up to date using pkg up.

There does seem to be an edgecase where our version of chsh -s doesn't handle absolute paths e.g $(which zsh) like the util-linux version.
I can take a look at that tomorrow.
Unsurprisingly:
% ls -l ~/.termux/shell
lrwxrwxrwx. 1 u0_a391 u0_a391 39 Mar 24 18:53 /data/data/com.termux/files/home/.termux/shell -> /data/data/com.termux/files/usr/bin/zsh
which explains why when I ssh to the phone I get the zsh shell
