variable = system(do something) 2

[pieretto]

Hi all,

in an awk script do you know if is possible to give a value from a "unix output command" to a variable?

I know that in a shell script I can give a value to a variable from a command output in this way:
In example: var1=`tail -1 InputFile.txt`

I need to do that in an awk script, so I'm thinking somenthing like this:

syscommand = "tail -1" InputFile "
var1 = system(syscommand)

but it doesn't work.

Do you have any suggestions?

Thanks
Piero

syscommand = "tail -1 " InputFile
syscommand | getline var1

Hope This Helps, PH.
