Computer Variable Manimpulation - special characters

Hello-

I have a variables that contains a string like this usr/pass@SCHEMA

I want to extract the usr/pass part and ignore the SCHEMA part, I tried to use this ${dbconn%%@} and apparently it will not work because @ is a special character. I tried \@ and still no go.

Any idea how to solve this problem will be much appreciated.

PS. Using ksh

Thanks,
Nomaad

NAME
basename, dirname - deliver portions of path names SYNOPSIS
/usr/bin/basename string [suffix] /usr/xpg4/bin/basename string [suffix] dirname string DESCRIPTION
The basename utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan- dard output. It is normally used inside substitution marks (``) within shell procedures. /usr/bin The suffix is a pattern defined on the expr(1) manual page. /usr/xpg4/bin The suffix is a string with no special significance attached to any of the characters it contains. The dirname utility delivers all but the last level of the path name in string. EXAMPLES
Example 1 Setting environment variables The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and the environment variable MYMAILPATH to the string /home/sms/personal: example% NAME=`basename $HOME/personal/mail` example% MYMAILPATH=`dirname $HOME/personal/mail` Example 2 Compiling a file and moving the output This shell procedure, invoked with the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current directory: example% cc $1 example% mv a.out `basename $1 .c` ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of basename and dirname: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: /usr/bin +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ /usr/xpg4/bin +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWxcu4 | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
