How to resize terminal window permanently using CLI?

Question

Inside the terminal when I type resize -s 50 50 terminal output is changed as rows 50 and columns 50.

But after closing the window and reopen terminal doesn't reflect the changes.

I want to open the terminal all time as rows 50 and columns 50.

I know this can be done using terminal Edit->Profile Preference->General setting with changing the rows and columns number, but I want to do this in CLI, because I have to do this inside a big script.

My .bashrc

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

# don't put duplicate lines or lines starting with space in the history.
# See bash(1) for more options
HISTCONTROL=ignoreboth

# append to the history file, don't overwrite it
shopt -s histappend

# for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000
HISTFILESIZE=2000

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# If set, the pattern "**" used in a pathname expansion context will
# match all files and zero or more directories and subdirectories.
#shopt -s globstar

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in

esac

# off by default to not distract the user: the focus in a terminal window
# should be on the output of commands, not on the prompt
#force_color_prompt=yes

if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
    # We have color support; assume it's compliant with Ecma-48
    # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
    # a case would tend to support setf rather than setaf.)
    color_prompt=yes

Result after pressing CtrlAltT

The default terminal size of Ubuntu is smaller than my monitor. When I install new OS I have to change many setting(customization), installation many software. So, I am making a script that do the customization and install all stuffs without my interruption. e.g.,

• change terminal window size
• make shortkey
• install firefox addons
• install software
• clone git repository.

Answer 1

First option

You can always run resize -s 50 50 at terminal launch using ~/.bashrc file. And to hide the command output just redirect it to the /dev/null device.

In other words, to resize the terminal using command line use:

echo "resize -s 50 50 >/dev/null" >> ~/.bashrc

Second option

After messing around with dconf-editor I believe I found exactly what you're searching for. gnome-terminal store its setting in dconf instead of config files. First you have to select the currently active terminal profile running this command:

currentprofile=$(gsettings get org.gnome.Terminal.ProfilesList default)

Then to set 50 rows as default run:

gsettings set org.gnome.Terminal.Legacy.Profile:/org/gnome/terminal/legacy/profiles:/:${currentprofile:1:-1}/ default-size-rows 50

And similarly for the columns:

gsettings set org.gnome.Terminal.Legacy.Profile:/org/gnome/terminal/legacy/profiles:/:${currentprofile:1:-1}/ default-size-columns 50

Done. Hope this helps

Answer 2

gnome-terminal

If I understand correctly, you are using standard Ubuntu and gnome-terminal, so you can use the following command line in your script,

gnome-terminal --geometry <columns>x<rows>

for example

gnome-terminal --geometry 135x45

You find the available options in man gnome-terminal.

xterm

The corresponding command line for good old xterm is

xterm -geometry 135x45

where you can add details to set the absolute position on the desktop (in pixels). Test these command lines,

xterm -geometry 90x25+0+0  # top left
xterm -geometry 90x25+0-0  # bottom left
xterm -geometry 90x25-0+0  # top right
xterm -geometry 90x25-0-0  # bottom right

and you can select other values than 0 for an arbitrary location.

You find the available options in man xterm (there are a lot of options).

Answer 3

It works for me when I unselected use custom default terminal size

Add add

resize -s 50 50 > /dev/null  

to ~/.bashrc

After pressing CtrlAltT

Copied from the link above:

Use the wmctrl command:

To list the windows:

$ wmctrl -l
0x00c00003 -1 rgamble-desktop Bottom Expanded Edge Panel
0x00c00031 -1 rgamble-desktop Top Expanded Edge Panel
0x00e00022 -1 rgamble-desktop Desktop
0x0260007c  0 rgamble-desktop Google - Mozilla Firefox

To resize a window based on its title:

wmctrl -r Firefox -e 0,0,0,640,480

The arguments to the resize option are gravity,X,Y,width,height so this will place the window at the top-left corner of the screen and resize it to 640X480.
