You didn't exactly follow what I said.

You don't append to the output file, otherwise all you do it end up with the file twice in the one file.

and don't use $newfile >> $newfile.

Use a different filename, or use the sed "in-place" replacement (which I never use, so check the man page for sed).

And yes. A single sed statement would make more sense.

either
Code:
sed -e "s/SOMETHING/SOMETHING_ELSE/g;s/ANOTHER_YETANOTHER/g" $file > $newfile
or
sed -e "s/SOMETHING/SOMETHING_ELSE/g" -e "s/ANOTHER_YETANOTHER/g" $file > $newfile

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>. SEE ALSO
