Default SED help
I would like to do the following SED replacement, but I am not having much
luck and thought I would ask for help.

TEXT1="some-text a.b.c.d a.b.c.d a.b.c.d a.b.c.d"
TEXT2="some-text 1.1.1.1 2.2.2.2 3.3.3.3 4.4.4.4"

sed -i "s/$TEXT1/$TEXT2/g" $INFILE

;a.b.c.d are unknown IP Addresses.

----------------------

I have tried this:

TEXT2="some-text 1.1.1.1 2.2.2.2 3.3.3.3 4.4.4.4"
IP_REGEX="(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).(25[0-5]|2[0-4][0-9]|[01]?[0-9][$
TEXT1="^some-text[ ]${IP_REGEX}[ ]${IP_REGEX}[ ]${IP_REGEX}[
]${IP_REGEX}"

sed -i "s/$TEXT1/$TEXT2/g" $INFILE

----------------------

What I have does not work, and I need some assistance.

Your help is appreciated.

Thanks.

My editor cut off some of the text, I assume due to line being too long.
Hopefully it is clear what I am trying to accomplish with the incomplete
information above


Thanks.

I think you simply missed out on the option: -e instead of -i. This
works for me:

TEXT1="some-text a.b.c.d a.b.c.d a.b.c.d a.b.c.d"
TEXT2="some-text 1.1.1.1 2.2.2.2 3.3.3.3 4.4.4.4"

sed -e "s/$TEXT1/$TEXT2/g" $INFILE

Kind regards,

Herta

Here is the poorly coded version I ended up with...

This is going to be used to dynamically update my openvpn configuration
server configuration.

#!/bin/sh

OUTFILE=/etc/openvpn/eth.txt
SED=`which sed`
PERL=`which perl`
OVPN_CFG=/etc/openvpn/mytest.txt

eth_ip=`/sbin/ifconfig | /bin/grep 'inet addr:'| /bin/grep -v '127.0.0.1'
| /usr/bin/cut -d: -f2 | /usr/bin/awk '{print $1}'`

echo $eth_ip > $OUTFILE

oct1=`/usr/bin/cut -d. -f1 $OUTFILE`
oct2=`/usr/bin/cut -d. -f2 $OUTFILE`
oct3=`/usr/bin/cut -d. -f3 $OUTFILE`
CLASS_C="${oct1}.${oct2}.${oct3}"

rm -f $OUTFILE

BRIDGE_STRING="server-bridge ${eth_ip} 255.255.255.0 ${CLASS_C}.30
${CLASS_C}.35"
IP_REGEX="d{1,3}.d{1,3}.d{1,3}.d{1,3}"
BRIDGE_REGEX="server-bridge[ ]${IP_REGEX}[ ]${IP_REGEX}[
]${IP_REGEX}[ ]${IP_REGEX}"

${PERL} -pi -e "s/${BRIDGE_REGEX}/${BRIDGE_STRING}/g" $OVPN_CFG

I believe, given what you say above, that you'd get
some-text 1111 1111 1111 1111

sed
-e 's/pchloe.com/abc.com/g'
-e 's/192.92.123.5/10.10.0.3/g'

You can also use semi colons for example:

sed 's/pchloe.com/abc.com/; s/192.92.123.5/10.10.0.3/g' orgfile >> newfile
