sed command working different in linux environment.

Hi
I tried running the code
Code:
scrname=`whence $0 | sed -e 's/\.\///g'`

where $0 is substituted by cm_dsjobrun.sh
in unix env then the value it returns me is

SCRNAME=/data/ds/dpr_ebicm_uat/etl/cm3_0/scripts/shell/cm_dsjobrun.sh

whereas i ran the same code on linux env

The value its returning me as in scrname as ''

I am not able to figure out why this is happening, could you all please help me. What changes should i make in the command so that it will return me the same output as it is giving in unix enviornment i.e .
Code:
SCRNAME=/data/ds/dpr_ebicm_uat/etl/cm3_0/scripts/shell/cm_dsjobrun.sh

Please help

Thanks.

I read on the whence command one point i would like to share is it detects it detects commands and aliases, and searches your path.
So my script path is searched properly in unix env... whereas this is not happening in the linux enviornment.
Could you all please help me in modifying the command so that i get the exact path of my script.

HI

To get the path in linux i tried
Code:
scrname={PWD}/$0

Where $0 will be script name.

My question is if i am using PWD instaed of whence in linux what difference it can cause to my script.

Thanks

NAME
diffmk - mark differences between versions of a troff input file SYNOPSIS
diffmk oldfile newfile markedfile DESCRIPTION
diffmk compares two versions of a file and creates a third version that includes "change mark" (.mc) commands for nroff(1) and troff(1). oldfile and newfile are the old and new versions of the file. diffmk generates markedfile, which, contains the text from newfile with troff(1) "change mark" requests (.mc) inserted where newfile differs from oldfile. When markedfile is formatted, changed or inserted text is shown by | at the right margin of each line. The position of deleted text is shown by a single *. USAGE
See largefile(5) for the description of the behavior of diffmk when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). EXAMPLES
Example 1 An example of the diffmk command. diffmk can also be used in conjunction with the proper troff requests to produce program listings with marked changes. In the following command line: example% diffmk old.c new.c marked.c ; nroff reqs marked.c | pr the file reqs contains the following troff requests: .pl 1 .ll 77 .nf .eo .nh which eliminate page breaks, adjust the line length, set no-fill mode, ignore escape characters, and turn off hyphenation, respectively. If the characters | and * are inappropriate, you might run markedfile through sed(1) to globally change them. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWdoc | +-----------------------------+-----------------------------+ SEE ALSO
diff(1), nroff(1), sed(1), troff(1), attributes(5), largefile(5) BUGS
Aesthetic considerations may dictate manual adjustment of some output. File differences involving only formatting requests may produce undesirable output, that is, replacing .sp by .sp 2 will produce a "change mark" on the preceding or following line of output. SunOS 5.11 14 Sep 1992 diffmk(1)
