Command puts in expect doesn't show the message in the order it should
I have a some scripts to automate a process and I want the message about which step I am in it shows in the command window. A piece of code I have is:
puts "** Creation of $VMNAME on $HOST begins... **"
spawn ssh -l $USER $HOST
expect_after eof {exit 0}
set timeout 10
expect "(yes/no)?" { send "yesr" }
expect "password:" { send "$PASSWORDr" }
expect "~]#" { send "dater" }
set timeout 1200
puts "** Transferring rhelvm img file to the $HOST... **"
expect "~]#" { send "scp somelink/rhelvm-0-vol.img /storage/iso/r" }
expect "Password:" { send "$TESTEMSPASSr" }
puts "** Transferring the VM conf from $TESTEMSUSER to $HOST... **"
expect "~]#" { send "scp somelink/$VMNAME.conf /rootr" }
expect "Password:" { send "$TESTEMSPASSr" }
puts "** Removing the $VMNAME... **"
expect "~]#" { send "/opt/ccm/bin/vmremove -f /root/$VMNAME.conf --forcer" }
sleep 10
expect "~]#" { send "rm -rf /storage/vmpool/*.imgr" }
sleep 10
puts "** Creating the $VMNAME... **"
expect "~]#" { send "/opt/ccm/bin/vmcreate -f /root/$VMNAME.conf -g /storage/iso/rhelvm-0-vol.img -er" }
sleep 10
puts "** Starting the $VMNAME ... **"
expect "~]#" { send "virsh start $VMNAMEr" }
sleep 10
expect "~]#" { send "virsh list --allr"}
expect "~]#" { send "dater" }
puts "** Creation of $VMNAME is completed. **"
expect "~]#" { send "exitr" }
but what I get in the output is not in this order for example it shows the message of creating the VM but then runs the rm -rf /storage/vmpool/*.img command.
I tried puts with -nonewline and send_user but nothing seems to work. Please help me!!

You may need to flush the output file. After each puts add the line
flush stdout
See the tcl flush command. Alternatively, you can set the output to non-buffered mode with a single line:
fconfigure stdout -buffering none
See tcl fconfigure.

I resolved the issue with including the puts in {} after expect and it worked. But I will look into your explanation also. thanks.
