How can I build the string before I call the system on the string?
The basic flow is this:
Read the next line in the file.
Cycle through each field in the file until it sees "Network address"
Knowing that the next field in the file after "Network address" is the DNS name of the
host, pass said DNS name to dig.
Put all of the IP addresses returned from dig, comma separated, on the line after the host name.
The command I'm passing works on the command line.
If I paste
on the command line, it works.
When I encase that in a print system([that string]) line, I get the following:
I tried escaping the apostrophes (backticks produced even more errors) and that didn't help either.
Take pity on me. I'm a router / switch / firewall guy who is having to write scripts to translate from Symantec SGS to Cisco. I speak Cisco. I'm brand new to scripting.
I am writing a shell script.
Now i need to read in a string and send it to an awk file to compare and search for compatible record.
I wrote it like tat:
read serial | awk -f generate.awk data.dat
p/s: the data file got 6 field.
According to an expert, we can write it like tat:

hosts
HOSTS(5) BSD File Formats Manual HOSTS(5)NAME
hosts -- host name data base
DESCRIPTION
The hosts file contains information regarding the known hosts on the network. For each host a single line should be present with the follow-
ing information:
Internet address
Official host name
Aliases
Items are separated by any number of blanks and/or tab characters. A ``#'' indicates the beginning of a comment; characters up to the end of
the line are not interpreted by routines which search the file.
Network addresses may either be specified for IP version 4 or version 6. IP version 4 addresses are specified in the conventional dotted
address notation. IP version 6 addresses are specified using the colon-separated notation described in RFC1924.
Host names may contain any printable character other than a field delimiter, newline, or comment character.
The hosts file is read by mDNSResponder(8) and used to supply results for calls to getaddrinfo(3), getnameinfo(3), etc. in addition to
results obtained from multicast and unicast DNS.
FILES
