Find out if multiple files have lines ending with"r"
I am trying to find out which files in a group of files have lines ending in r. What I have is this:

Code:
cat /tmp/*RECORDS| if grep r$>/dev/null; then echo "yes";else echo"no";fi

Records is more than one file. There are the following files

Code:
TEST-RECORDS
/volume/testing
/volume/programs
 
INFO-RECORDS
/volume/101r     -example of line that ends in r
/volume/listingr
 
CATALOG-RECORDS
/volume/catar
/volume/catx

I was trying to use this command to find out which Records had "r" but of course it returns yes when run because if even one file has a volume ending in R it would return "yes."

If I do this:

Code:
for i in `cat /tmp/*RECORDS`; do if $i grep $r>/dev/null; then echo "yes";fi;done

Then I get a load of messages "no such file or directory" and the names of the files.

I am really just trying to find out which of these files has a line ending in r, and then print yes for just that file, but I am stuck.

Does anyone have any ideas?

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
