Append text to end of every line
I've scoured the internet with mixed results. As an amateur I turn to the great minds here.

I have a text file of 80 or so lines. I want to add ".pdf" to the end of each line. (For now that's it)

Most of the internet points toward using "sed". I don't know coding but can figure things out (enough to paint myself into a corner). The closest I've gotten is:

Code:
sed 's/$/.pdf/' input

which will print within the shell:

Code:
lastlineofinput.pdf

instead of appending ".pdf" to each line within the file.

awk '{NR==1?s=$0 : s=s".pdf"$0}END{print s}' input.txt
did the same thing.

Operators are largely beyond me. I see different solutions involving different amounts of single and double quotations and I'm not sure which ones I should use.

I have had success with finding and replacing text using sed.

Code:
sed s/'text1'/'text2'/g inputfile.txt > outputfile.txt

that's a lot more than I knew before today, though admittedly more straightforward (it appears).

The closest I came was one bit of code (I forgot which now) that inserted a period to the end of the very last line. Nowhere else.

My goal is to go from this:

/02/pdf/01
/02/pdf/02
/02/pdf/03
/02/pdf/04
/02/pdf/05
/02/pdf/06

to this:
/02/pdf/01.pdf
/02/pdf/02.pdf
/02/pdf/03.pdf
/02/pdf/04.pdf
/02/pdf/05.pdf
/02/pdf/06.pdf

I'm on a Mac using Terminal so I don't know what I'm doing and appreciate any help. Thank you!

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
       ps2pdf14 - Convert PostScript to PDF 1.4 (Acrobat 5-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|-]
       ps2pdf14  [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 in a file of the same name with a '.pdf' extension  in  the  current  working
       directory.  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).

       -      ps2pdf14 will always produce PDF 1.4 output (Acrobat 5-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, ps2pdf13 or ps2pdf14, 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.

OPTIONS

       The ps2pdf scripts use the same options as gs(1).

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
