Quickly determine lines in terminal

_llines=100; while [ $_llines -gt 1 ]; do echo $_llines; _llines=$(($_llines-1)); done
You've opened a terminal window and you've connected off to a remote host that didn't pick up your terminal size, and all your curses and paging apps are screwed up as a result. You need to quickly determine how many lines are in your current terminal view (to feed into "stty rows X").

What Others Think

Argh! Horrible. How about using tput to determine screen characteristics: (it's part of the ncurses library) Number of lines: tput lines Number of columns tput cols

Because that doesn't always work. Right now I am going from Cygwin to a Linux box over ssh. I've resized the DOS window. But the change hasn't passed over. `tput lines` says: 71. But running my snippet shows that the terminal is actually 98 lines tall. tput is wrong because it gets its values from what the session THINKS is the terminal size. That doesn't necessarily match the real terminal size.

It wouldn't make any sense to do something like stty rows `tput lines` because stty and tput both work with the same values. The point is when the shell's idea of your terminal window size and your actual terminal window size is out of sync.
