You haven't told us what operating system or shell you're using, and grep is not capable of joining text from different lines in a file. For that you need something more like awk. For example:
Code:
#!/bin/ksh
IAm=${0##*/}
if [ $# -ne 1 ]
then	printf 'Usage: %s column_1_value\n' "$IAm" >&2
	exit 1
fi
awk -v pattern="^$1 " '
FNR == 2 {
	line2 = $0
	next
}
$0 ~ pattern {
	print line2, $0
}' dump[1-9]????.data dump[1-9]?????.data dump[1-9]??????.data > particle"$1".dat

Although written and tested using a Korn shell, this will also work with any shell that meets basic POSIX shell requirements for parameter expansions and uses Bourne shell syntax.

If you want to try this on a Solaris/SunOS system, change awk in this script to /usr/xpg4/bin/awk or nawk.

igawk

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
