Description Jeroen Wouters 2021-12-02 10:34:06 UTC 
Description of problem:
The bash wrapper script /usr/bin/sage starts bash with the "-i" argument for an interactive shell. This does not seem to be necessary and prints the below error message when sage is called from non-shell programs (such as the sagemath plugin for TeXmacs).

Version-Release number of selected component (if applicable): 9.4-2.fc35


How reproducible: always


Steps to Reproduce:
1. Start sage from a non-shell program (e.g. as a sagemath session in TeXmacs)

Actual results:
An error message is displayed

bash: cannot set terminal process group (2411): Inappropriate ioctl for device
bash: no job control in this shell

Expected results:
No error messages.

Additional info:
Removing the "-i" argument seems to have no effect on the functioning of sage, neither interactively on the command line, nor non-interactively when executing a .sage script or from the Jupyter notebook.

This script seems to be Fedora specific, it is not in upstream.
