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.

For multiple columns

Hi All,

good morning.

I have an output file out of a native database in the following format..
Code:
term_id = "ABCDEF"
post_dat = "20090905"
hpr1_amt_beg = 30090000

term_id = "ade"
post_dat = "20090904"
hpr1_amt_beg = 3009123
 
term_id = "DEF"
post_dat = "20090903"
hpr1_amt_beg = 30090030

and i need it to be printed in the following format...
Code:
 
term_id post_dat hpr1_amt_beg
ABCDEF 20090905 30090000 
ADE    20090904 30090030
DEF    20090903 30090030

I tried using awk & sed...but somehow the output format is not exactly coming as above.Can somebody help me out here...Thanks mates.

Hi Malcolm,

The following is the syntax which i tried a while ago...
Code:
 
awk '{FS = "="}{printf $1" "$2" "}' test.out >> test1.out

Here the test.out is the input file which contains the contents
Code:
term_id = "ABCDEF"
post_dat = "20090905"
hpr1_amt_beg = 30090000
term_id = "ade"
post_dat = "20090904"
hpr1_amt_beg = 3009123
term_id = "DEF"
post_dat = "20090903"
hpr1_amt_beg = 30090030

..and i get the output as follows in a single line...
Code:
 
term_id   "ABCDEF" post_dat   "20090905" hpr1_amt_beg   30090000   term_id   "ade" post_dat   "20090904" hpr1_amt_beg   3009123   term_id   "DEF" post_dat   "20090903" hpr1_amt_
beg   30090030

i believe somewhere i have to break the line when the "term_id" column starts to print it in the next line.I am doing trial and error.i hope i will crack it soon.
