why am I losing line-end chars
Hello,

I do not know why the output from these two methods differs. One method retains the newlines, the other method appears to ignore or lose the newlines.

Writing a file with the redirection operator:

egrep -e 'matchstring' infile.txt > outfile.txt

The resulting outfile.txt contains separated line when viewing the file.

However, when I do this method (with the goal of having all the output lines in a variable called OUTFILE), the resulting text appears to have lost all the line breaks:

OUTFILE=$(egrep -e 'matchstring' infile.txt)

Thank you!

ps2epsi

PS2EPSI(1)							 Ghostscript Tools							PS2EPSI(1)

NAME

       ps2epsi - generate conforming Encapsulated PostScript

SYNOPSIS

       ps2epsi infile.ps [ outfile.epsi ] (Unix)
       ps2epsi infile.ps [ outfile.epi ] (DOS)

DESCRIPTION

       ps2epsi	uses  gs(1)  to  process a PostScript(tm) file and generate as output a new file which conforms to Adobe's Encapsulated PostScript
       Interchange (EPSI) format.  EPSI is a special form of encapsulated PostScript (EPS) which adds to the beginning of the file in the form	of
       PostScript  comments  a bitmapped version of the final displayed page.  Programs which understand EPSI (usually word processors or DTP pro-
       grams) can use this bitmap to give a preview version on screen of the PostScript.  The displayed quality is often not very good (e.g.,  low
       resolution, no colours), but the final printed version uses the real PostScript, and thus has the normal PostScript quality.

USAGE

       On Unix systems invoke ps2epsi like this:

	    ps2epsi infile.ps [ outfile.epsi ]

       where "infile.ps" is the input file and "outfile.epsi" is the resulting EPSI file.  If the output filename is omitted, it is generated from
       the input filename.  When a standard extension (".ps", ".cps", ".eps" or ".epsf") is  used,  it	is  replaced  with  the  output  extension
       ".epsi".  On DOS systems the command is:

	    ps2epsi infile.ps outfile.epi

       where "infile.ps" is the original PostScript file, and "outfile.epi" is the name of the output file.

LIMITATIONS

       Not every PostScript file can be encapsulated successfully, because there are restrictions on what PostScript constructs a correct encapsu-
       lated file may contain.	ps2epsi does a little extra work to try to help encapsulation, and it automatically calculates	the  bounding  box
       required  for  all  encapsulated  PostScript  files, so most of the time it does a pretty good job. There are certain to be cases, however,
       where the encapsulation does not work because of the content of the original PostScript file.

COMPATIBILITY

       The Framemaker DTP system is one application which understands EPSI files, and ps2epsi has been tested on a number of  PostScript  diagrams
       from  a	variety  of  sources, using Framemaker 3.0 on a Sun workstation.  Framemaker on other platforms should be able to use these files,
       although I have not been able to test this.

FILES

       ps2epsi	     Unix shell script
       ps2epsi.bat   DOS batch file
       ps2epsi.ps    the Ghostscript program which does the work
