ssh command output to save in a text file in shell script

Question

I want to write shell script, in which i am using ssh command. Whatever output i will get through ssh command i want save this in text file or varibale, so i can use this in my shell script. Currently i am saving output in a variable , but when i used that variable outside ssh command , value is showing blank. Code is

ssh hostname -c "'
`pwd`;
var=$(ps -ef | grep Consumer | cut -f6 -d' ')
'";
echo $?;

echo "vbar  $var";

var value is blank when i print.

im not sure, but i think this form might help: ssh XXXXXXX > outfile.txt; cat outfile.txt — user230910

It's blank, because var gets assigned a value in a bash session running on the remote machine (ssh). However, your variable evaluation happens at the local session. — anishsane

To save ssh's output in local file "file.log":

ssh hostname > file.log << EOF
pwd
ps -ef | grep Consumer | cut -f6 -d' '
EOF

How can use one ssh for two commands to save 2 different files. Like one command is ps -ef | grep Consumer | cut -f6 -d' ' and save this output in file.log, second command is ps -ef | grep Test | cut -f7 -d' ' and save output in test.log
