Convert column values into row

hi,
I have a requirement where in I read the values from a file using awk. The resulting data should be converted into row format from column format.

For ex: My log file login.lst contains the following
Code:
SERVER1 DB1
SERVER2 DB2
SERVER3 DB3
SERVER4 DB4

I use awk to grep only the server names as below

SERV=`cat login.lst | awk '{print $1}' `

echo $SERV prints the output ..

SERVER1
SERVER2
SERVER3
SERVER4

I want the output to be formatted as -- SERVER1 SERVER2 SERVER3 SERVER4

I tried to search the forum for any similar posts, but I couldnt find any clear definition or matching cases.

Can someone please help.

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 SEE ALSO
