dear frineds:
i want to run top command in connected computers with opensuse 12.1.
pssh -h hostsfile -i top
but it gives me the following error:
dingpeng@ReNeng-01:~> pssh -h hostsfile -i top
[1] 08:29:09 [FAILURE] 192.168.1.1 Exited with error code 1
Stderr: TERM environment variable not set.
[2] 08:29:09 [FAILURE] 192.168.1.3 Exited with error code 1
Stderr: TERM environment variable not set.
[3] 08:29:09 [FAILURE] 192.168.1.4 Exited with error code 1
Stderr: TERM environment variable not set.
[4] 08:29:09 [FAILURE] 192.168.1.2 Exited with error code 1
Stderr: TERM environment variable not set.

could you please gives me some sugesstions about this error

Either set the TERM variable or better: use top in batch mode with 'top -n1 -b' and receive output on stdout. *Note if you want to run top on several hosts continuously then you probably suffer from "using the wrong tool for the right job" syndrome in the sense of never having heard of Monit, Nagios, SNMP, etc, etc...

thank you very much
it works. but how to output the first 25 lines of top command in each nodes.
i run the following commad, but it seems that it does not work
pssh -h hostsfile -i top -n1 -b|head -n25

In this case this should work:
