How do I find number of vertical lines available in the terminal?
I’m writing a script which shows the
git log for a directory when I
cd into it.
Such a log can be overwhelming, containing hundreds of lines. So far I have been limiting that to a hard-coded 30 lines with (
... | head -n 30), cool on the big screen at Work, too big at home. I would prefer the log to take up about half the (vertical) screen on any terminal, e.g. Gnome at work, iTerm2 at home. I do not use screen or tmux. But would like to learn them.
How do I find the number of vertical lines available in a terminal from command line?
This command should give you the number of lines on the terminal:
stty size | cut '-d ' -f1
Some systems might not implement
stty size so you might need something like this instead:
stty -a | tr ; \012 | grep rows | tr -d ' rows'
Terminal parameters are stored as
Additionally you can use special term-operation programm, for example
tput lines # outputs the number of lines of the present terminal window.
tput cols # outputs the number of columns of the present terminal window.
