Rudic -
To show the "raw" value of $ORACLE_SID at a command line:

Code:
oracle:hr92upg$ echo $ORACLE_SID
hr92upg

And to show no hidden characters, I'll append an 'x' on each end:

Code:
oracle:hr92upg$ echo x${ORACLE_SID}x
xhr92upgx

And, as requested, the ps and grep, without the -v to filter out the grep itself

Code:
oracle:hr92upg$ ps -ef|grep pmon_$ORACLE_SID
oracle    1237     1  0 10:37 ?        00:00:01 ora_pmon_hr92upg
oracle   31557 28288  0 12:59 pts/0    00:00:00 grep pmon_hr92upg

And in the interest of full disclosure, all possible 'pmon' processes:

Code:
oracle:hr92upg$ ps -ef|grep pmon
oracle    1237     1  0 10:37 ?        00:00:01 ora_pmon_hr92upg
oracle    1631     1  0 Jan22 ?        00:00:46 ora_pmon_fs91dmo
oracle    2842     1  0 Jan22 ?        00:00:35 ora_pmon_fs91upg
oracle    4317     1  0 Jan22 ?        00:00:49 ora_pmon_fs91dev
oracle    9786     1  0 Jan04 ?        00:03:03 ora_pmon_fs92upg
oracle   10156     1  0 Jan04 ?        00:03:02 ora_pmon_hr92dev
oracle   21794     1  0 Jan05 ?        00:02:58 ora_pmon_fs92dev
oracle   23261     1  0 Jan25 ?        00:00:11 ora_pmon_hr92tst
oracle   31578 28288  0 12:59 pts/0    00:00:00 grep pmon

Compare the above with the list of possible values for ORACLE_SID generated at line 61 of my script, and displayed at line 63

tabs

TABS(1) 						    BSD General Commands Manual 						   TABS(1)

NAME

     tabs -- set terminal tabs

SYNOPSIS

     tabs [-n | -a | -a2 | -c | -c2 | -c3 | -f | -p | -s | -u] [+m[n]] [-T type]
     tabs [-T type] [+[n]] n1[,n2,...]

DESCRIPTION

     The tabs utility displays a series of characters that clear the hardware terminal tab settings then initialises tab stops at specified posi-
     tions, and optionally adjusts the margin.

     In the first synopsis form, the tab stops set depend on the command line options used, and may be one of the predefined formats or at regular
     intervals.

     In the second synopsis form, tab stops are set at positions n1, n2, etc.  If a position is preceded by a '+', it is relative to the previous
     position set.  No more than 20 positions may be specified.

     If no tab stops are specified, the ``standard'' UNIX tab width of 8 is used.

     The options are as follows:

     -n      Set a tab stop every n columns.  If n is 0, the tab stops are cleared but no new ones are set.

     -a      Assembler format (columns 1, 10, 16, 36, 72).

     -a2     Assembler format (columns 1, 10, 16, 40, 72).

     -c      COBOL normal format (columns 1, 8, 12, 16, 20, 55)

     -c2     COBOL compact format (columns 1, 6, 10, 14, 49)

     -c3     COBOL compact format (columns 1, 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58, 62, 67).

     -f      FORTRAN format (columns 1, 7, 11, 15, 19, 23).

     -p      PL/1 format (columns 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61).

     -s      SNOBOL format (columns 1, 10, 55).

     -u      Assembler format (columns 1, 12, 20, 44).

     +m[n], +[n]
	     Set an n character left margin, or 10 if n is omitted.

     -T type
	     Output escape sequence for the terminal type type.

ENVIRONMENT

     The LANG, LC_ALL, LC_CTYPE and TERM environment variables affect the execution of tabs as described in environ(7).

     The -T option overrides the setting of the TERM environment variable.  If neither TERM nor the -T option are present, tabs will fail.

EXIT STATUS

     The tabs utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     expand(1), stty(1), tput(1), unexpand(1), termcap(5)

STANDARDS

     The tabs utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A tabs utility appeared in PWB UNIX.  This implementation was introduced in FreeBSD 5.0.

BUGS

     The current termcap(5) database does not define the 'ML' (set left soft margin) capability for any terminals.
