How to escape from the shell
In a Script I need to push several messages to a function.
My problem here is: I have to print the string v$LOCK on the resulting line which spits out the message. What I want here is not printing the contents of $LOCK I want to escape the shell and printout v$LOCK on the line. But don't know how to.

#!/bin/sh
AWK="/bin/awk"
RESULT="30"
DBPKG="vserver56"

message() {
${AWK} -F## '{system("echo \"" $1 "\" hostname='$DBPKG' severity=" $2 " sub_origin=\""$3"\" script=\"'$SCRIPT'\" \"" $4 "\" SENTRY")}'
}

echo "There is a session locking since $RESULT minutes. See v$LOCK!##CRITICAL##$METAGONIS_APPLICATION##GE_RPM_blocking_waits" | message


Spits out:
There is a session locking since 30 minutes. See v! hostname=vserver56 severity=CRITICAL sub_origin= script= GE_RPM_blocking_waits SENTRY


But should Spit out:
There is a session locking since 30 minutes. See v$LOCK! hostname=vserver56 severity=CRITICAL sub_origin= script= GE_RPM_blocking_waits SENTRY

addseverity

ADDSEVERITY(3)						     Linux Programmer's Manual						    ADDSEVERITY(3)

NAME

       addseverity - introduce new severity classes

SYNOPSIS

       #include <fmtmsg.h>

       int addseverity(int severity, const char *s);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       addseverity(): _SVID_SOURCE

DESCRIPTION

       This  function  allows  the introduction of new severity classes which can be addressed by the severity argument of the fmtmsg(3) function.
       By default that latter function only knows how to print messages for severity 0-4 (with strings (none), HALT, ERROR, WARNING, INFO).   This
       call attaches the given string s to the given value severity.  If s is NULL, the severity class with the numeric value severity is removed.
       It is not possible to overwrite or remove one of the default severity classes.  The severity value must be nonnegative.

RETURN VALUE

       Upon success, the value MM_OK is returned.  Upon error, the return value is MM_NOTOK.  Possible errors include: out of memory,  attempt	to
       remove a nonexistent or default severity class.

VERSIONS

       addseverity() is provided in glibc since version 2.1.

CONFORMING TO

       This function is not specified in the X/Open Portability Guide although the fmtmsg(3) function is.  It is available on System V systems.

NOTES

       New severity classes can also be added by setting the environment variable SEV_LEVEL.
