EXPECT question: removing last line from expect_out(buffer)

[ianfo]

Hi,

I have an expect question......

Given the following contents of expect_out(buffer)

uname -a
SunOS xx 5.8 Generic_108528-15 sun4u sparc SUNW,Sun-Fire
xxxx

does anyone know how I can remove the last line from the buffer? (its contents could be varying so I cant just use string trimright xxxx)

i want to just have

uname -a
SunOS xx 5.8 Generic_108528-15 sun4u sparc SUNW,Sun-Fire

Thanks for any help you can give!

you can use tail, head, awk, perl and so on,
i prefere sed:

sed -ne '/^uname/,/^SunOS/p'
