Shell Programming and Scripting

Hi,

I use this command in Linux but if I run the same command does not work in freebsd.

Follow the below command:

Linux works:

sed -e '1731a\' -e '####' squid.conf > squid2.conf ; sed -e '1731a\' -e 'acl TESTE_ip src 192.168.1.1/255.255.255.255' squid2.conf > squid.conf ; sed -e '1731a\' -e '########' squid.conf > squid2.conf ; sed -e '1731a\' -e '#####' squid2.conf > squid.conf

Freebsd displays the following error:

sed: 1: "acl TESTE_ip src 192.16 ...": command a expects \ followed by text

Could someone help me ?

Tks

Maybe you need to esacpe it with \, like this \/ and try.

thank you for reply.

I already tried to escape with \ the 'a' command the '\/'.

In this message, something to do with the command a(append) that I put together with the line.

sed: 1: "acl TESTE_ip src 192.16 ...": command a expects \ followed by text.

On Linux it works perfect but does not work in freebsd.

The a is not the line but the 'acl ...., i try escape '\acl but now other error display.

"\acl TESTE_ip src 192.1 ...": unterminated regular expression

Try double quotes around that entire string.

It would really help if you would clearly state what it is that you are trying to accomplish.

In any case, a guess: With regard to POSIX, GNU/Linux sed is a mess. GNU goes beyond compatible extensions and happily disregards basic command behavior (most notably, the N command). If you are trying to append text, use a newline after the backslash after the a command.

Code:

sed '1731a\
####' squid.conf'

If you are not attempting to add a line of "####" after the 1731st line, then please explain further.

Thanks for the reply.

Exactly, but I would like to add multiple lines and this command line would I assign a variable as:

$exec = "sed '1731a\ ####' squid.conf'"

How will I assign a variable with line break?

The output in a text file "squid.conf" would be:

#####
acl TESTE_ip src 192.168.1.1/255.255.255.255
########

tksss

Absolutely no point. Anything that could possibly be special to the shell is already protected by strong quotes (single quotes).

That command line will most likely just throw an error. You can't have whitespace around the "=" in an assignment.

Why don't you do yourself and us a favor and walk us through what it is that you are trying to accomplish. Step by step. Assume nothing. Break it down. Give us a few lines of input and the expected output. If you are trying to assign or extract something into a variable, give us context.
