problems faced while using ssh

[kknegi]

Hi all,

we are using OpenSSh 3.7.1p1 version in both unix and Windows environment.
Also we had sucessfully implemented Password Less Authentication to connect to unix machine from windows using SSH.

we are able to run a script made in unix end but the same script is not getting executed when we try to run it through windows command prompt.

To make the picture more clear i will show u the errors which we are getting while executing the script from Windows command prompt:-

C:\>ssh [e-mail] /home/shadm/shcalc/DateProject/test.sh > test1.log

grep: can't open rates.rel
expr: Syntax error
grep: can't open canada_exchange_rate.txt
grep: can't open month_midmonth_release.txt
sed: Cannot find or open file month_midmonth_release.txt.

Even we changed the permissions for the above files for which we are getting the error, but still we are not able to open those files from Windows End.

Is there something to do with SSH permissions????

can anyone please help us in this regard.

Regards,
Kishore

Does your shell script contain the full file path for the files that are giving an error? (rates.rel, canada_exchange_rate.txt, month_midmonth_release.txt)

What does this script look like?

You realize that the script will be executed with its working directory
set to shadm's $HOME, correct?

Most likely, you forgot to quote something properly.  In general, I
abhor the use of expr(1) in shell scripts.  Its only real purpose is
in writing legacy (pre-POSIX, pre-ksh) Bourne shell scripts.  There
are shell builtins that can do almost everything expr does, but faster
and cleaner.

I think the fact that you're sitting in $HOME instead of wherever you
expected to be is the most likely candidate for all three of these.

Sounds more like you need a few pointers in writing shell scripts.
