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?

vgexport

vgexport(1M)															      vgexport(1M)

NAME

       vgexport - export an LVM volume group and its associated logical volumes

SYNOPSIS

       mapfile] outfile] vg_name

       mapfile vg_name

DESCRIPTION

       Using  the  format  of  the  first command line of the above, the command can be used to remove a volume group from the system.	The volume
       group will be removed without modifying the logical volume information found on the physical volumes.

       The volume group identified by vg_name is removed from the or file, and the associated device files including  the  vg_name  directory  and
       file are removed from the system.

       The  volume group information and data is untouched on the physical volume.  These disks can be imported to another system with the command
       (see vgimport(1M)).

   Scan Option
       Using the format of the second command line of the above, the command generates a mapfile that can be copied to other systems that are part
       of a high availability cluster (use the option if you do not want to remove the volume group from the system the command is being run from)
       and the command (see vgimport(1M)) can be used to recreate the volume group.  See also vgchange(1M).  The mapfile contains a description of
       the  volume group and its associated logical volume(s) (if any).  The logical volume information found on the physical volumes is not modi-
       fied.

   Options and Arguments
       recognizes the following options and arguments:

	      vg_name	     The path name of the volume group.

	      By default, a file named
			     is created in the current directory.  This file contains a description of the volume group and its associated logical
			     volume(s)	(if  any).   Use  this option to specify a different name for the file, mapfile.  This file can be used as
			     input to (see vgimport(1M)).  When used with the option, the volume group specified in the mapfile can be shared with
			     other systems in the high availability cluster.

	      Preview the actions to be taken but do not update the
			     or file or remove the devices file.  This option is best used in conjunction with the option.

	      Print verbose messages
			     including the names of the physical volumes associated with this volume group.

	      Scan option.   When the option is specified, then the options must also be specified.  A mapfile is created that can be used to cre-
			     ate volume group entries on other systems in the high availability cluster (with the command).

	      Write the current set of
			     pv_paths for the volume group to the outfile.  The outfile may then be used as the infile for the	option.   If  used
			     together  with  the option the volume group is not exported but the list of pv_paths is still written to the outfile.
			     This may be useful to derive a list of pv_paths for the volume group or to use on another system which is sharing the
			     volume group and which has an identical configuration.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Export the volume group into mapfile The volume group will be removed from the exporting system.

       Export the volume group and write the disk names into the file

       Create  a  mapfile to be copied to other systems in a high availability cluster to build the volume group information for the volume group,
       Note that the volume group is not removed from the exporting system.  The importing systems will create the volume group with  the  command
       using the and options.
