sed - go to file and search a part and set at the end text
Hello,

i hope the titel is okay.

I want to edit a line in
Code:
/etc/arno-iptables-firewall/firewall.conf

So the Line can contains:
Code:
OPEN_TCP="436, 25, 80, 110, 143, 443, 465, 587, 993, 995, 21, 20"

i want to search in this line:
Code:
OPEN_TCP="*, *, 80, *, *, 443, *, *, *, *"

and i want to insert at the end of this line
Code:
OPEN_TCP="*, *, 80, *, *, 443, *, *, *, *,$FTP_PORT"


anyone a idea to help me?

So, there MUST be 8 stars in the line, plus the 80, plus the 443?

No, the stars (*) are unknown content.

My line looks so:
Code:
OPEN_TCP="436, 25, 80, 110, 143, 443, 465, 587, 993, 995"


So the constant is
Code:
OPEN_TCP="

Is it possible to search in this file for:
Code:
OPEN_TCP="

and add some contant so:
Code:
OPEN_TCP="$FTP_PORT,

that the line after this looks so:
Code:
OPEN_TCP="21, 436, 25, 80, 110, 143, 443, 465, 587, 993, 995"

This is NOT at line end as requested in post#1 ?! Try
Code:
sed "/OPEN_TCP=\"/ s//&$FTP_PORT, /" /etc/arno-iptables-firewall/firewall.conf

Yes, because I noticed while writing that it is so simple



Thank you for helping me, i use this:
Code:
 sed -i "s/OPEN_TCP=\"/OPEN_TCP=\"$FTP_PORT,/g" /root/firewall.conf

but i like your code much more


but one Problem:
is it possible to say di this:
Code:
 sed -i "s/OPEN_TCP=\"/OPEN_TCP=\"$FTP_PORT,/g" /root/firewall.conf

,

Only for the last match? or "exact this string"

So i habe in my firewallconf Strings like this:
Code:
LAN_HOST_OPEN_TCP=""
LAN_INET_OPEN_TCP=""
LAN_INET_HOST_OPEN_TCP=""

After i use my bash script the lines look so:
Code:
LAN_HOST_OPEN_TCP="22"
LAN_INET_OPEN_TCP="22"
LAN_INET_HOST_OPEN_TCP="22"

Thats not what i want.

"my" OPEN_TCP is the last OPEN_TCP in the Document:

Only for the last matching line, this is difficult.
Exact match, this is easy: just put the ^ anchor
Code:
sed -i "s/^OPEN_TCP=\"/&$FTP_PORT,/" /root/firewall.conf

Also changed: & re-inserts the matching portion, g (retry) modifier not needed.
The following would avoid a duplicate insertion
Code:
sed -i "/\<$FTP_PORT\>/ "\!"s/^OPEN_TCP=\"/&$FTP_PORT,/" /root/firewall.conf

he brakes the line after this code:
Code:
BIG_PORTS="111,222,333,444,555,666,777,888,999"
sed -i "/\<$BIG_PORTS\>/ "\!"s/^OPEN_TCP=\"/&$BIG_PORTS,/" /etc/arno-iptables-firewall/firewall.conf

result:
Code:
OPEN_TCP="111,222,333,444,555,666,777,888,999
,436, 25, 80, 110, 143, 443, 465, 587, 993, 995, 21, 20"
OPEN_UDP=""
OPEN_IP=""

why he do that? How i can get this result:
Code:
OPEN_TCP="111,222,333,444,555,666,777,888,999,436, 25, 80, 110, 143, 443, 465, 587, 993, 995, 21, 20"
OPEN_UDP=""
OPEN_IP=""
