Storing lines of output into a script variable
I'm sure this is a simple thing but I can't figure it out. In a script that I'm writing, I'd like to be able to store each line of output from "ls -l" into a variable. Ultimately I'd like to end up with something like:

Code:
for a in `ls -l`
do something with $a
done

But that's reading each individual word from the entire output instead of each line. I can go into much more detail about what I'm trying to accomplish if I need to, but that's the basics of it. Thanks in advance for any help you can provide!

ps2pdf12

PS2PDF(1)							    Ghostscript 							 PS2PDF(1)

NAME

       ps2pdf - Convert PostScript to PDF using ghostscript
       ps2pdf12 - Convert PostScript to PDF 1.2 (Acrobat 3-and-later compatible) using ghostscript
       ps2pdf13 - Convert PostScript to PDF 1.3 (Acrobat 4-and-later compatible) using ghostscript

SYNOPSIS

       ps2pdf  [options...] {input.[e]ps|-} [output.pdf|-]
       ps2pdf12  [options...] {input.[e]ps|-} [output.pdf|-]
       ps2pdf13  [options...] {input.[e]ps|-} [output.pdf|-]

DESCRIPTION

       The ps2pdf scripts are work-alikes for nearly all the functionality (but not the user interface) of Adobe's Acrobat(TM) Distiller(TM) prod-
       uct: they convert PostScript files to Portable Document Format (PDF) files.

       If the output filename is not specified, the output is placed is a file of the same name with a '.pdf' extension. Either the input filename
       or the output filename can be '-' to request reading from stdin or writing to stdout, respectively, when used as a filter.

       The three scripts differ as follows:

       -      ps2pdf12 will always produce PDF 1.2 output (Acrobat 3-and-later compatible).

       -      ps2pdf13 will always produce PDF 1.3 output (Acrobat 4-and-later compatible).

       -      ps2pdf  per se currently produces PDF 1.4 output.  However, this may change in the future. If you care about the compatibility level
	      of the output, use ps2pdf12 or ps2pdf13, or use the -dCompatibility=1.x switch in the command line.

       There are some limitations in ps2pdf's conversion. See the HTML documentation for more information. A large number of  Adobe  Distiller(TM)
       parameters  which  can  be  used to control the conversion are also documented there, including instructions for generating PDF/X and PDF/A
       documents.

EXAMPLES

       Converting a figure.ps to figure.pdf:

	      ps2pdf figure.ps

       A conversion with more specifics:

	      ps2pdf -dPDFSETTINGS=/prepress figure.ps proof.pdf

       Converting as part of a pipe:

	      make_report.pl -t ps | ps2pdf -dCompatibility=1.3 - - | lpr
