however ssh IP "df -k" > output works fine

Sounds like the machine doesn't have the top command installed, or it's in a dir thats not in PATH.

no friend, top commands works absolutely fine on prompt. The thing is that it is not working in a script.
Its like
top -d1 > file is working

but

ssh -l root IP "top -d1" > file is not working.

Try:

Code:

ssh remotehost top -bn1 > output

The reason that it doesn't work is that if top is outputting to a terminal (normal operation), it uses the curses library to perform operations such as setting bold/inverse video fonts, moving the cursor etc.

These operations have no meaning when re-directing output to a file, and so curses does not work (complaints about the TERM variable). Using the -b option tells top to print in a way which is OK for re-direction.

hey again, this works absolutely fine for Linux Machines, but in Solaris Machines i am getting error.

Check the manual page in the Solaris machine and see if there is a similar option for the version of top which installed there. I seem to have some memory from an old sunos4 machine which I worked on that it does, but I do not recall what it is.

Another thought - maybe the Solaris machines do not support option clustering. I also found a manual page on the net which said -n was an alias to -b, so try them separately. Try each of these and see if they help:

Code:

ssh remotehost top -b -n 1 > output
ssh remotehost top -b > output
ssh remotehost top -n > output

THANKS TO ALL, ssh IP "/usr/bin/top -b -n1" works well on solaris as well as linux machines.
