Do programs in /bin or /usr/bin should be invoked from a shell?












0















I started my Chrome and Firefox from search bar and find they were also opened from a terminal



user@host:~$ pstree -aps 5221 | head -10
systemd,1 splash
`-gdm3,1027
`-gdm-session-wor,2418
`-gdm-x-session,2529 --run-script env GNOME_SHELL_SESSION_MODE=ubuntu /usr/bin/gnome-session --session=ubuntu
`-gnome-session-b,2545 --session=ubuntu
`-gnome-shell,2741
`-chrome,5221
|-cat,5227
|-cat,5228
|-chrome,5232


Chrome was invoked from a GUI utility called gnome-shell.



Does any installed software should be run from a form of terminal?



Additionally, I find the terminal I am working is not named tty but



user@host:~$ tty
/dev/pts/0


and can't communicate with tty2



 user@host:~$ echo "very strange long text" > /dev/tty2
user@host:~$ grep -r 'very strange long text' / 2>/dev/null


does not return valuable message, the text to tty2 lost.
