Reassign value to a string variable
hi to all,

i have a string variable that i want to reassign a new value in it through a script and i am having some trouble.
i write the following if statement:

Code:
if [ $checkupd!="lastupdate" ]
then
$checkupd="lastupdate = "
fi

in this statement i check if the variable checkupd contains the word "lastupdate". if it doesnt contain this word then i want to assign it as a value of this variable. when i run it i get the following error:
Code:
=lastupdate = : not found

do i have to assign it with different way?

thank you for your time

crl

CRL(1)								      OpenSSL								    CRL(1)

NAME

       crl - CRL utility

SYNOPSIS

       openssl crl [-inform PEM|DER] [-outform PEM|DER] [-text] [-in filename] [-out filename] [-noout] [-hash] [-issuer] [-lastupdate]
       [-nextupdate] [-CAfile file] [-CApath dir]

DESCRIPTION

       The crl command processes CRL files in DER or PEM format.

COMMAND OPTIONS

       -inform DER|PEM
	   This specifies the input format. DER format is DER encoded CRL structure. PEM (the default) is a base64 encoded version of the DER form
	   with header and footer lines.

       -outform DER|PEM
	   This specifies the output format, the options have the same meaning as the -inform option.

       -in filename
	   This specifies the input filename to read from or standard input if this option is not specified.

       -out filename
	   specifies the output filename to write to or standard output by default.

       -text
	   print out the CRL in text form.

       -noout
	   don't output the encoded version of the CRL.

       -hash
	   output a hash of the issuer name. This can be use to lookup CRLs in a directory by issuer name.

       -issuer
	   output the issuer name.

       -lastupdate
	   output the lastUpdate field.

       -nextupdate
	   output the nextUpdate field.

       -CAfile file
	   verify the signature on a CRL by looking up the issuing certificate in file

       -CApath dir
	   verify the signature on a CRL by looking up the issuing certificate in dir. This directory must be a standard certificate directory:
	   that is a hash of each subject name (using x509 -hash) should be linked to each certificate.

NOTES

       The PEM CRL format uses the header and footer lines:

	-----BEGIN X509 CRL-----
	-----END X509 CRL-----

EXAMPLES

       Convert a CRL file from PEM to DER:

	openssl crl -in crl.pem -outform DER -out crl.der

       Output the text form of a DER encoded certificate:

	openssl crl -in crl.der -text -noout

BUGS

       Ideally it should be possible to create a CRL using appropriate options and files too.
