thanks

thanks bakunin,
the explanation was perfect.
but i am afraid it didnt work.
I have this inside a loop and I cant make it work Smilie
Because I belive the sed is appending write under the
string: alias 24x7-comunicacions
Or is it because >> dosent work well, or both?
THe result is only the first LINEX

echo "$LINESB" | while read line; do
#COUNTS THE LINES, FIRST LINE IS BAD! THEN ADD "members $HOSTNAME, each line TO maps.txt"
: $((LCOUNT = $LCOUNT + 1))
if [ $LCOUNT -gt 1 ]; then
#echo $LCOUNT
LINEX=" members $HOSTNAME,$line"
echo "$LINEX"
sed '/alias 24x7-comunicacions/a\'"$LINEX" "$FILECFG" >>temp.txt
fi
done

ECHO(1) 						    BSD General Commands Manual 						   ECHO(1)

NAME
echo -- write arguments to the standard output SYNOPSIS
echo [-n] [string ...] DESCRIPTION
The echo utility writes any specified operands, separated by single blank (' ') characters and followed by a newline (' ') character, to the standard output. The following option is available: -n Do not print the trailing newline character. This may also be achieved by appending 'c' to the end of the string, as is done by iBCS2 compatible systems. Note that this option as well as the effect of 'c' are implementation-defined in IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002. Applications aiming for maximum portability are strongly encouraged to use printf(1) to sup- press the newline character. Some shells may provide a builtin echo command which is similar or identical to this utility. Most notably, the builtin echo in sh(1) does not accept the -n option. Consult the builtin(1) manual page. EXIT STATUS
The echo utility exits 0 on success, and >0 if an error occurs. SEE ALSO
builtin(1), csh(1), printf(1), sh(1) STANDARDS
The echo utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'') as amended by Cor. 1-2002. BSD
