If there are 2 lines in file1 and 2 lines in file2, in which of the following ways should they be combined:
file1line1 file2line1
file1line2 file2line2
or
file1line1 file2line1
file1line1 file2line2
file1line2 file2line1
file1line2 file2line2
Also, to help us help you, provide better feedback. Simply saying "did not work" is not useful. Provide the exact error messages generated on your system (what os and shell are you using?). If there are no errors but the output differs from what you expect, describe how it deviates.Provide some sample input. If there are weird characters showing up, show us the code you ran, the input it used, and tell us exactly what characters they are.

this is the thing that i need:
file1line1 file2line1
file1line1 file2line2
file1line2 file2line1
file1line2 file2line2
actually there are no errors. in vbe's solution, no output file was created i also tried to add a couple of echo commands but they did not show up. as for the paste command, i do not think it will work since i need every line from file 1 to join with every line from file 2. i am using ksh and the machine is HP-UX.
sample contents of FILE1
SERVERA
SERVERB
sample contents of FILE2

paste
PASTE(1) BSD General Commands Manual PASTE(1)
NAME
paste -- merge corresponding or subsequent lines of files
SYNOPSIS
paste [-s] [-d list] file ...
DESCRIPTION
The paste utility concatenates the corresponding lines of the given input files, replacing all but the last file's newline characters with a
single tab character, and writes the resulting lines to standard output. If end-of-file is reached on an input file while other input files
still contain data, the file is treated as if it were an endless source of empty lines.
The options are as follows:
-d list Use one or more of the provided characters to replace the newline characters instead of the default tab. The characters in list
are used circularly, i.e., when list is exhausted the first character from list is reused. This continues until a line from the
last input file (in default operation) or the last line in each file (using the -s option) is displayed, at which time paste
begins selecting characters from the beginning of list again.
The following special characters can also be used in list:
newline character
tab character
\ backslash character
Empty string (not a null character).
Any other character preceded by a backslash is equivalent to the character itself.
-s Concatenate all of the lines of each separate input file in command line order. The newline character of every line except the
last line in each input file is replaced with the tab character, unless otherwise specified by the -d option.
If '-' is specified for one or more of the input files, the standard input is used; standard input is read one line at a time, circularly,
for each instance of '-'.
EXAMPLES
List the files in the current directory in three columns:
ls | paste - - -
Combine pairs of lines from a file into single lines:
paste -s -d '
' myfile
Number the lines in a file, similar to nl(1):
sed = myfile | paste -s -d '
' - -
Create a colon-separated list of directories named bin, suitable for use in the PATH environment variable:
find / -name bin -type d | paste -s -d : -
DIAGNOSTICS
The paste utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
cut(1), lam(1)
STANDARDS
The paste utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
HISTORY
A paste command appeared in Version 32V AT&T UNIX.
BUGS
Multibyte character delimiters cannot be specified with the -d option.
