Hi,
I have a bunch of a files in  a directory. Is there a simple one line
command (without using foreach)
to run awk on all files in the directory?
(Say I want to print th efifth line of all files in the directory). I
tried something like
awk 'NR ==5' < (ls *)
any variants of the above, but it did not work. any idea on how this
can be done?
Thanks

Maybe you should use
awk 'FNR =3D=3D 5' *

Aside from the fact that NR == 5 will only work with the first file, the
easy way is 

  awk 'FNR==5' *

If the directory doesn't have other directories
cat * | awk 'NR =3D=3D 5'

Probably you can play with the find(1)  command also

No, with this command you concatenate all files then
extract the fifth line.

Simply use as said by others

	awk 'FNR=3D=3D5' *

Yes, with find you can using something like

    find ./ -maxdepth 1 -type f -exec awk 'NR=3D=3D5' {} \;

for files in current directory only, of course.
