sed -Replacing file path within .txt file
Hi,

I am trying to use sed to replace a file path within all the .lay (.txt) files in a folder. I feel that this should be easy but I can't get it to work no matter what i try.

I'm using cygwin.

For a .txt file containing the below line I want to replace this file path with a new one.
Code:
$!VarSet |LFDSFN1| = '"E:\OLD\FILE\PATH TO DATA\data.txt"

Below is what i think should work.
Code:
old_file_path="E:\OLD\FILE\PATH TO DATA\data.txt"
new_file_path="E:\new\file\path"

sed -e 's|$old_file_path|$new_file_path|g' *.lay

I've tried placing the variables inside the command, defining the input and output files. I've changed the delimeter to |, as using back or forward slashes is problematic with file names. I have tried other methods on fouums, but can't get anything to work.

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>.
