hi guys,
i'm trying to solve the following problem and cannot find any working
solution. it might seem to be very specialized on the first sight, but i
think it's pretty general (and probably pretty easy)
i'm using pbs pro queueing system and there is a tool called pbsdsh that
runs given command and parameters on every node of a cluster allocated
for a job. i.e.,
pbsdsh ls -la /path/to/file
will print info about file on every node where it is run. however,
pbsdsh ls -la /path/to/file*
will not work because the wildcard is expanded on the 'master' host,
i.e. the machine where this command was typed. this can be solved by
pbsdsh -- /bin/sh -c 'ls -la /path/to/file*'
i.e., executing a shell with some parameters. however in the following
case, i'm lost:
export MASTER_HOST=`hostname`
export FILE_PATH=some_file_path
pbsdsh -- /bin/sh -c 'scp $FILE_PATH/file* $MASTER_HOST:'
because i want wildcard '*' to be expanded on the target machine and the
variable to be expanded on the master host ($MASTER_HOST and FILE_PATH
are not defined on the other nodes).
i would be very grateful for any hints how to accomplish this. it might
be really easy, but i don't see any solution :(
thanks,
