Machine Type: x86_64-pc-linux-gnu
Bash Version: 5.2
Patch Level: 21
Release Status: release
Description:
Process does not become foreground when run from a pipe.
Repeat-By:
Conditions are very special, and I am not sure who in the chain is cause of
bug.
In short the bug in the following line, but it should executed not from a
running terminal emulator:
uxterm -e bash -c 'echo /etc/fstab | { FILE="$(cat)" ; sudoedit "$FILE"
; }'
It line of script must be run automatically from the WM.
The chain to reproduce:
| sway wm | | uxterm | | bash ... sudoedit |
| i3 wm | --> | alacritty | -> | |
| weston | | | | |
swaywm config file:
exec_always uxterm -e bash -c 'echo /etc/fstab | { FILE="$(cat)" ;
sudoedit "$FILE" ; }'
If sudoedit running not from a pipe, it works good. Some of terminal
emulators do not reproduces
the problem, such as `foot` or `xfce4-terminal`.
The result of the chain is an editor isn't gain a focus and I cant type
anything.
Again, I'm not sure that is definetely bash, but could you please check
that. Thank you.
