Subject: Extracting the 4th word of the first line in a file - is there a more elegant solution?
Date: Fri, 18 May 2012 15:16:54 +0200	[thread overview]
Message-ID: <1337347014.26363.140661077285713.26DAE636@webmail.messagingengine.com> (raw)

Within a script, I have need to store the 4th word in the first line of
a file.

Of course this is trivial to implement. However, I'm curious whether
there exists a better way to implement than what I found.

My current solution goes like this:

# $1 is the filename
line=$(head -n 1 $1)
field=${lin[(w)4]}

This is OK, but this needs an auxiliary variable 'line'. 


I could also do it like this:

field=$(head -n 1 $1|cut  -f 4 -d ' ')

No aux variable, but needs a pipe


So I wonder, whether there is a elegant "zsh" solution, which solves
this in a more elegant way?
