How to write on sd card

[Yisus7u7]

Hello, and accessed my sd card from termux (no root), the sd card supports executables and this would be of great help to me, but termux can not write files on it, gives you permission denied, can I fix it?

Writing to external removable sd card and USBs is not officially supported by Android with shell commands and is only supported with SAF. It may work on some devices, but not all. You can't do anything to change that without root.

probably it is restricted in read only but with full write access to it's app directory
/storage/1234-5678/Android/data

Normal command line applications won't be able to write in external storage completely but Android apps can have full access into it with full write permissions

Ok, thank you very much, the sd card if you allow executables, the rare thing is that the application folder (com.termux) does not allow them

@Yisus7u7 Access to your external data should be possible by Steps: Deny and Allow in the Android Storage Setup for the Termux app. This is actually made by termux-setup-storage (you've already done), but sometimes does not work, especially with Android 11 devices. Sometimes a reboot also helps to get access to df|grep storage|cut -d% -f2.
Scripts can also be saved on sdcard and run there e.g. with: ln -s /storage/44C4-1B1A/bstart .bashrc or 'bash .bashrc`
