remote execution of find -exec
Hi folks

I am working on a script which lists files of a specific pattern on a remote m/c and tar&zip them to another remote m/c via a centralized server.

M/C details:

remote1 - OSF1 vayu V5.1 2650 alpha
remote2 - cygwin based windows server
central - SunOS phys-chenab 5.8 Generic_117350-61 sun4u sparc SUNW,Sun-Fire-15000

LAYOUT
*******

remote1(vayu) -------> central (chenab) ----------> remote2 (cygwin windows)


Have a issue with the script which seriously retards me . The logic is to check if a particular file has already been transferred , and if not transfer the same . This checking happens at the remote side through remsh. This part works well when executed directly on remote1 but fails when executed from central server.


set -f;cd /usr1/smscomn/data/cards/spool/ ;find /usr1/smscomn/data/cards/spool/ -name "CS507.11.[0-9]*.47.*" -exec bash -c ' grep $0 /usr1/smscomn/data/cards/status_vayu | grep success ; if [ `echo $?` -eq 0 ] ;then printf "$0 copied \n" ; else printf " $0 transferred already \n" ; fi ' {} {} \; ;set +f


remsh vayu "set -f;cd /usr1/smscomn/data/cards/spool/ ; find /usr1/smscomn/data/cards/spool/ -name "CS507.11.[0-9]*.47.*" -exec bash -c ' grep $0 /usr1/smscomn/data/cards/status_vayu | grep success ; if [ `echo $?` -eq 0 ] ;then printf " copied"; echo $0 ; else printf $0 transferred ; fi ' {} {} \; ;set +f "

Output:

copiedbash
copiedbash
copiedbash
copiedbash


$0 parameter of bash -c should be filename output of find but why is it pointing to prog name which is bash .

Moreover when i change bash -c to sh -c , i expect output to be "copiedsh" ; but its still "copiedbash"

Can you please provide some light on whats happening? . I am open to corrections and suggestions and even harsh rebuke over insanity of the code.

SYNOPSIS

       sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port]

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.
