rsh exit code

[Jens-Uwe Spiering]

Hi all,
for a command like this

rsh host -l user test -f /pathtofile/file

i got always success for the return code $?
OK the rsh command succeeded but how can i get the result of the test command?
Thanx for any input

$ rc=`rsh tuvan 'ls nofile 2> /dev/null ; echo $?'`
$ echo $rc

rc now contains the return code of the command.

Regards,

Thanks Nick,
the echo is working fine, but as often the next problem is waiting, may be you
have an answer as well
if i rsh host 'test -f /mypath/myfile ; echo $?' everything is fine
but i don't know for wich path and file i should ask in advance so i put
variables

rsh host 'test -f $MyPath/$MyFile ; echo $?'

but that does not work. Perhaps the test command on the remote does not know
the variables although they are known locally when the rsh command is started.
Can i somehow get the remote test command to check for my variables??

If the local system environment contains $MyPath and $MyFile, you
need to enclose the command in double quotes -- not single quotes --
to allow your local shell to interpolate the variables.

Yes!
Now are the vars are expanded to their value, but again i get only success in
echo $?
Probably this variable is as well expanded and don't take the return value of
the test command

Exists=`rsh host "test -f $MyPath/$MyFile ; echo $?" `

so i tried to keep that echo $? away from the main shell with again single
quotes and and and...
to no result ;)
Any idea are more than welcome

Hello Jens,

in a korn-shell script try the following:

rc=$(rsh host "test -f $Mypath/$Myfile && echo found || echo failed")

echo $rc

REgards,

Hi,
you would want to mask the semicolon and other special characters from
rsh like this:
rsh remotehost \(thiscommand \; thatcommand 2\>\&1 \)

h.t.h.
regards, Markus

Either use double quotes and escape the variables (twice) that you
don't want interpolated or switch quoting styles as appropriate.

exists=`rsh host "test -f $mypath/$myfile; echo \\$?"`
exists=`rsh host "test -f $mypath/$myfile; "'echo $?'`
