cat can not open file

Hi All,

I have stumbled upon very unique issue. In my script I am doing cat file and then greping and cutting so as to assign the value to variable. My file is,

<mxc_tl_load_extractdata_prop.bsh>

Code:
DB_USER=test_oper hostname=xxx FTP_USER=test1_operate
MAIL_LIST=xxx@yyy.com SLEEPTIME=7200 PROD_CONN=aaa.bb.cc.com UAT_CONN=bbb.bb.cc.com PROD_FTP_HOST=x1.bb.cc.com UAT_FTP_HOST=y1.bb.cc.com



In my script ,
Code:
FTP_USER=`cat mxc_tl_load_extractdata_prop.bsh| grep -i "FTP_USER"|cut -d"=" -f2`



This command did not work and gives error as
cat: cannot open mxc_tl_load_extractdata_prop.bsh

But in the same script after above command next variable "hostname" is able to be extracted (with exact same command) and is assigned to variable.

The script worked on "SunOS 5.8 Generic_117350-55 sun4us sparc FJSV,GPUZC-Land" but issue is coming on "SunOS 5.10 Generic_137111-04 sun4u sparc SUNW,SPARC-Enterprise"

I have alrady checked for white space issue.

Can anybody help? Smilie

Regards

NAME
cat, read, nobs - catenate files SYNOPSIS
cat [ file ... ] read [ -m ] [ -n nline ] [ file ... ] nobs [ file ... ] DESCRIPTION
Cat reads each file in sequence and writes it on the standard output. Thus cat file prints a file and cat file1 file2 >file3 concatenates the first two files and places the result on the third. If no file is given, cat reads from the standard input. Output is buffered in blocks matching the input. Read copies to standard output exactly one line from the named file, default standard input. It is useful in interactive rc(1) scripts. The -m flag causes it to continue reading and writing multiple lines until end of file; -n causes it to read no more than nline lines. Read always executes a single write for each line of input, which can be helpful when preparing input to programs that expect line-at-a- time data. It never reads any more data from the input than it prints to the output. Nobs copies the named files to standard output except that it removes all backspace characters and the characters that precede them. It is useful to use as $PAGER with the Unix version of man(1) when run inside a win (see acme(1)) window. SOURCE
/src/cmd/cat.c /src/cmd/read.c /bin/nobs SEE ALSO
cp(1) DIAGNOSTICS
Read exits with status eof on end of file or, in the -n case, if it doesn't read nlines lines. BUGS
Beware of and which destroy input files before reading them. CAT(1)
