Environment

Termux 0.118.0
Android 14
Python 3.11.8

Additional context

I made a simple fix and fixed my problem but haven't tested on other platforms.

Hmm didn't realize that termux doesn't have /usr/bin/env... Maybe a better way to fix this is testing if /usr/bin/env exists, use which bash if it doesn't exist

[hykilpikonna]

I think I fixed it. Please test it and lmk if it works or doesn't work

It works now! Thanks for your fix.

Just saw this issue in the release notes. Here's my two cents as to why.

• Terminal emulators on Android, including Termux although more of a proot environment, always use Android's own rootfs when it comes to executions relative to root (/).
• Android, being built different, has no /usr directory to begin with AFAIK. All executables that are there in Linux distros are scattered across system, product, vendor and sometimes oem/odm partitions. There's a /bin in the rootfs, of course, which is a symlink to /system/bin.
• Termux works around this by adding its own usr directory, located in /data/data/com.termux/files/usr, into PATH while launching its profile within the app - This behavior could theoretically be replicated in a root shell, but I'm still yet to discover that.
• Above is also the reason why Termux's package manager utilities, I.e. APT and PKG, refuse to work as root, because it would potentially impact the stability of or even completely break your ROM instead.
