Hi Perl Gurus,
perl -e 'print "http://www.site@domain.com"'
The output of the above is :
http://www.site.com"
I want to print http://www.site@domain.com without using escape sequence before '@' like '\@'.
Is there any way to do this in perl?
Thanks,

ib_acme
ib_acme(7) ib_acme ib_acme(7)NAME
ib_acme - test and configuration utility for the IB ACM
SYNOPSIS
ib_acme [-f addr_format] [-s src_addr] -d dest_addr [-v] [-c] [-P] [-S svc_addr] [-C repetitions]
ib_acme [-A [addr_file]] [-O [opt_file]] [-D dest_dir] [-V]
DESCRIPTION
ib_acme provides assistance configuring and testing the ibacm service. The first usage of the service will test that the ibacm is running
and operating correctly. The second usage model will automatically create address and configuration files for the ibacm service.
OPTIONS -f addr_format
Specifies the format of the src_addr and dest_addr parameters. Valid address formats are: 'i' ip address, 'n' host name, 'l' lid,
'g' gid, and 'u' unspecified. If the -f option is omitted, an unspecified address format is assumed. ib_acme will use getaddrinfo
or other mechanisms to determine which format the address uses.
-s src_addr
Specifies the local source address of the path to resolve. The source address can be an IP address, system network name, or LID, as
indicated by the addr_format option.
-d dest_addr
Specifies the destination address of the path to resolve. The destination address can be an IP address, system network name, or
LID, as indicated by the addr_format option.
-v Indicates that the resolved path information should be verified with the active IB SA. Use of the -v option provides a sanity check
that resolved path information is usable given the current cluster configuration.
-c Instructs the ACM service to only returned information that currently resides in its local cache.
-P Queries performance data from the destination service
-S svc_addr
address of ACM service, default: local service
-C repetitions
number of repetitions to perform resolution. Used to measure performance of ACM cache lookups. Defaults to 1.
-A [addr_file]
With this option, the ib_acme utility automatically generates the address configuration file ibacm_addr.cfg. The generated file is
constructed using the system host name and any IP addresses that are assigned to IPoIB device instances.
-O [opt_file]
With this option, the ib_acme utility automatically generates the option configuration file ibacm_opts.cfg. The generated file is
currently generated using static information.
-D dest_dir
Specify the destination directory for the output files.
-V Enables verbose output. When combined with -A or -O options, ib_acme will display additional details, such as generated address
information saved to the ibacm_addr.cfg file.
NOTES
The ib_acme utility performs two main functions. With the -A and -O options, it automatically generates address or options configuration
files. The generated files are text based and may be edited. These options are intended to provide a simple way to configure address and
option information on all nodes on a cluster.
The other function of the ib_acme utility is to test the ibacm service, including helping to verify that the service is usable given the
current cluster configuration. The ib_acme utility can resolve IP addresses, network names, or IB LIDs into a path record. It can then
compare that path record against one obtained by the SA. When used to test the ibacm service, the ib_acme utility has the side effect of
loading the ibacm caches.
Multiple, numerical destinations can be specified by adding brackets [] to the end of a base destination name or address. Users may spec-
ify a list of numerical ranges inside the brackets using the following example as a guide: node[1-3,5,7-8]. This will result in testing
node1, node2, node3, node5, node7, and node8.
