Terminal resized command

Yes. Terminal supports escape sequences for manipulating windows, including the size and position, layering, and minimizing. Dimensions can be expressed in pixels or characters. See Xterm Control Sequences for details (search for “Window manipulation”; if you’re not familiar with the notation, “CSI” stands for “Control Sequence Introducer”, which is ESC [).

For example, this shell command will set the window to 100x50 characters:

printf '\e[8;50;100t'

Minimize the window for a few seconds, then restore it:

printf '\e[2t' && sleep 3 && printf '\e[1t'

Move the window to the top/left corner of the display:

printf '\e[3;0;0t'

Zoom the window:

printf '\e[9;1t'

Bring the window to the front (without changing keyboard focus):

printf '\e[5t'

Enabling the Control Sequences in Terminal Emulators

Some terminal emulators ignore these control sequences by default and require configuration to enable them.

To enable these in XTerm, set the following resource to true:

allowWindowOps

To enable these in iTerm2, deselect the following preference:

Preferences > Profiles > [profile] > Terminal > Disable session-initiated window resizing

How to pipe a 'yes' or 'y' into a program while invoked with 'sudo' in bash?

How to pipe a Y or yes to a program while invoking with sudo?

We can type like this

yes | command
yes | yum update

How to pipe the y from yes into a program via sudo like the following?

yes| sudo command

The y from yes is be passed into command and should go into sudo and sudo shall ask for password normally. How can I do this?

sudo reads the password from the terminal directly, not from its standard input, unless the -S option is used. Thus

yes | sudo command

should prompt for the password (if necessary), without reading from yes, then run command as root with its standard input fed from yes’s standard output.

If that doesn’t work, you can run the whole pipeline under sudo using something like

sudo sh -c "yes | command"
