very useful tip for embedded Linux engineers and those who work with Linux Console using minicom or teraterm

normally if we type ps in serial console, it will show the process , if the length is more than 80 character(which is default) we cannot see the string after 80 characters in the consol,

with the below command you can adjust the width of the terminal with cols argument and number of rows using the  argument rows to the command stty

stty cols 160 rows 40

this can be used separate also

stty cols 160

stty rows 50

Hope this help in ps and htop command when u run and other applications
