Pseudo-terminal will not be allocated because stdin is not a terminal ssh bash -

okay heres part of code when ssh servers server.txt list.

while read server <&3;   #read server names while loop     servername=$(uname -n)  if [[ ! $server =~ [^[:space:]] ]] ;  #empty line exception     continue  fi     echo server on list = "$server"  echo server signed on = "$servername"  if [ $servername == $server ] ; #makes sure server doesnt try ssh     continue  fi     echo "connecting - $server"     ssh "$server"  #ssh login     echo connected "$servername"     exec < filelist.txt     while read updatedfile oldfile;     #   echo updatedfile = $updatedfile #use troubleshooting     #   echo oldfile = $oldfile   #use troubleshooting                if [[ ! $updatedfile =~ [^[:space:]] ]] ;  #empty line exception                 continue # empty line exception                fi                if [[ ! $oldfile =~ [^[:space:]] ]] ;  #empty line exception                 continue # empty line exception                fi              echo comparing $updatedfile $oldfile             if diff "$updatedfile" "$oldfile" >/dev/null ;                 echo files compared same. no changes made.             else                 echo files compared different.                 cp -f -v $oldfile /infanass/dev/admin/backup/`uname -n`_${oldfile##*/}_$(date +%f-%t)                 cp -f -v $updatedfile $oldfile              fi               done  done 3</infanass/dev/admin/servers.txt 

i keep on getting error , ssh doesn't connect , perform code on server suppose ssh'd on.

pseudo-terminal not allocated because stdin not terminal 

i feel guy above said wrong.

expect?

it's simple:

ssh -i ~/.ssh/bobskey bob@10.10.10.10 << eof echo creating file called apples in /tmp folder touch /tmp/apples exit eof 

everything in between 2 "eof"s run in remote server.

the tags need same. if decide replace "eof" "waynegretzky", must change 2nd eof also.
