Hallo,
why use 'c\A...'
from man page:
c \
text Replace the selected lines with text, which has each embedded newline preceded by a backslash.
---------
It is not clear to me if the \n should be embedded or not?
Would it not better to use:
sed -e 's/regexp/replacement/' filename
->
sed -i -e 's/^ADDRESS.*$/ADDRESS=1.2.3.4/' filename
That works fine:
[root at bkvme2:~]# sed -e 's/^ADDRESS.*$/ADDRESS=1.2.3.4/' test.txt
ADDRESS=1.2.3.4
NETMASK=
GATEWAY=
[root at bkvme2:~]# cat test.txt
ADDRESS=
NETMASK=
GATEWAY=
[root at bkvme2:~]#
