using sed to remove lines
Can somebody explain why my sed command is not working.

I do the folloinwg:

Generates a binary file to /tmp/x1.out
Code:
/usr/lib/sa/sa2 -s 4:00 -e 8:00 -i 3600 -A -o /tmp/x1.out

decodes the file (no problem so far)
Code:
sar -f /tmp/x1.out

When I do this it does not appear to delete the lines from the top of
the file. Why is that.

Code:
sar -f /tmp/x1.out  | sed '2d'

I know this sar command is writing to stdout since when I do this I see the contents of the output in the new file.

Code:
sar -f /tmp/x1.out  1> /tmp/j1.out

Thanks in advance to all who answer this post

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
