Sorting error in bash?

Question

I have this line of code where i go to the 4th column , get the maximum number and print it out

maximum=$(sort -u -k4 -nr Logname.csv | tail-2)

but its showing me this error

sort: fflush failed: standard output: Broken pipe sort: write error

Anyone can help me fix this?

Is it within a bash script or embedded in a Python or another language? — fedorqui, Apr 01 '14 at 09:48

tail-2 is not a command, so there is no process running for sort to write its output to, hence the "broken pipe" error. You forgot the space:

maximum=$(sort -u -k4 -nr Logname.csv | tail -2)
