Hi,
So what I'm trying to do is
I have these variables and if they have a dot in them , I want everyting before and including the dot removed.
Any ideas ?
Something like this I would want :

I want to save that removal $var... (2 Replies)
HOw can I use any variable in sed command.
For example I am using 'sed -e 's/?/$ORACLE_HOME/g' $file_name
Here it replaces ? with $ORACLE_HOME. Instead of it I need actual value of $ORACLE_HOME. How can I do that?
Please advice.
Thanks in advance.

Hi,
My shell script searches a VALUE in a file, copies it to a variable and updates a line in another file with this new VALUE (replacing the old)
The value has a pattern-
VALUE=`$$MyDate=11-11-2008 09.09.56.123456`
(yes the $ - . = and space are all part of the string)

spkac
SPKAC(1) OpenSSL SPKAC(1)NAME
spkac - SPKAC printing and generating utility
SYNOPSIS
openssl spkac [-in filename] [-out filename] [-key keyfile] [-passin arg] [-challenge string] [-pubkey] [-spkac spkacname] [-spksect
section] [-noout] [-verify] [-engine id]
DESCRIPTION
The spkac command processes Netscape signed public key and challenge (SPKAC) files. It can print out their contents, verify the signature
and produce its own SPKACs from a supplied private key.
COMMAND OPTIONS -in filename
This specifies the input filename to read from or standard input if this option is not specified. Ignored if the -key option is used.
-out filename
specifies the output filename to write to or standard output by default.
-key keyfile
create an SPKAC file using the private key in keyfile. The -in, -noout, -spksect and -verify options are ignored if present.
-passin password
the input file password source. For more information about the format of arg see the PASS PHRASE ARGUMENTS section in openssl(1).
-challenge string
specifies the challenge string if an SPKAC is being created.
-spkac spkacname
allows an alternative name form the variable containing the SPKAC. The default is "SPKAC". This option affects both generated and input
SPKAC files.
-spksect section
allows an alternative name form the section containing the SPKAC. The default is the default section.
-noout
don't output the text version of the SPKAC (not used if an SPKAC is being created).
-pubkey
output the public key of an SPKAC (not used if an SPKAC is being created).
-verify
verifies the digital signature on the supplied SPKAC.
-engine id
specifying an engine (by its unique id string) will cause spkac to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default for all available algorithms.
EXAMPLES
Print out the contents of an SPKAC:
openssl spkac -in spkac.cnf
Verify the signature of an SPKAC:
openssl spkac -in spkac.cnf -noout -verify
Create an SPKAC using the challenge string "hello":
openssl spkac -key key.pem -challenge hello -out spkac.cnf
Example of an SPKAC, (long lines split up for clarity):
SPKAC=MIG5MGUwXDANBgkqhkiG9w0BAQEFAANLADBIAkEA1cCoq2Wa3Ixs47uI7F

NOTES
A created SPKAC with suitable DN components appended can be fed into the ca utility.
SPKACs are typically generated by Netscape when a form is submitted containing the KEYGEN tag as part of the certificate enrollment
process.
The challenge string permits a primitive form of proof of possession of private key. By checking the SPKAC signature and a random challenge
string some guarantee is given that the user knows the private key corresponding to the public key being certified. This is important in
some applications. Without this it is possible for a previous SPKAC to be used in a "replay attack".
