Note that with standard sed (non-GNU) there needs to be a ; before the trailing }:
or we can avoid the braces by using negation style:
--
Alternatively we can avoid the sub shell / external command altogether with just standard shell:
--
Note also that these are all naive approaches without knowing what the format of config.boot looks like. Also, if the are more inet configs in the same file, these will only pick the first one indiscriminately.

Hi!
Been working on a script and I've been having a problem. I've finally narrowed it down to this variable I'm setting:
servername=$(awk -v FS=\/ '{ print $7 } blah.txt | sed 's\/./-/g' | awk -v FS=\- '{print $1}')"
This will essentially pare down a line like this:

Hi, wondering if it's been asked before but didn't find matches from google. Basically I have this line:

Now somehow the '\t' from the echo output gets replaced with white space and then stored in $myvar.
It creates a problem for me later to use tab as delimiter to do... (2 Replies)

in.iked
in.iked(1M) System Administration Commands in.iked(1M)NAME
in.iked - daemon for the Internet Key Exchange (IKE)
SYNOPSIS
/usr/lib/inet/in.iked [-d] [-f filename] [-p level]
/usr/lib/inet/in.iked -c [-f filename]
DESCRIPTION
in.iked performs automated key management for IPsec using the Internet Key Exchange (IKE) protocol.
in.iked implements the following:
o IKE authentication with either pre-shared keys, DSS signatures, RSA signatures, or RSA encryption.
o Diffie-Hellman key derivation using either 768, 1024, or 1536-bit public key moduli.
o Authentication protection with cipher choices of DES, Blowfish, or 3DES, and hash choices of either HMAC-MD5 or HMAC-SHA-1. Encryption
in in.iked is limited to the IKE authentication and key exchange. See ipsecesp(7P) for information regarding IPsec protection
choices.
in.iked starts at boot time if the /etc/inet/ike/config file exists. See ike.config(4) for the format of this file.
in.iked listens for incoming IKE requests from the network and for requests for outbound traffic using the PF_KEY socket. See pf_key(7P).
in.iked has two support programs that are used for IKE administration and diagnosis: ikeadm(1M) and ikecert(1M).
The SIGHUP signal causes the IKE daemon to read /etc/inet/ike/config and reload the certificate database. SIGHUP is equivalent to using
ikeadm(1M) to read the /etc/inet/ike/config file as a rule, for example:
example# ikeadm read rule /etc/inet/ike/config
OPTIONS
The following options are supported:
-c Check the syntax of a configuration file.
-d Use debug mode. The process stays attached to the controlling terminal and produces large amounts of debugging output.
-f filename Use filename instead of /etc/inet/ike/config. See ike.config(4) for the format of this file.
-p level Specify privilege level (level). This option sets how much ikeadm(1M) invocations can change or observe about the running
in.iked.
Valid levels are:
0 Base level
1 Access to preshared key info
2 Access to keying material
If -p is not specified, level defaults to 0.
SECURITY
This program has sensitive private keying information in its image. Care should be taken with any core dumps or system dumps of a running
in.iked daemon, as these files contain sensitive keying information. Use the coreadm(1M) command to limit any corefiles produced by
in.iked.
FILES
/etc/inet/ike/config
/etc/inet/secret/ike.privatekeys/*
Private keys. A private key must have a matching public-key certificate with the same filename in /etc/inet/ike/publickeys/.
/etc/inet/ike/publickeys/*
Public-key certificates. The names are only important with regard to matching private key names.
/etc/inet/ike/crls/*
Public key certificate revocation lists.
/etc/inet/secret/ike.preshared
IKE pre-shared secrets for Phase I authentication.
