redirect each command output to respective log file expect script

set commands {"show phone xxx 11""show phone yyy 22""show phone zzz 33"}spawn ssh -o StrictHostKeyChecking=no $UserId@$hostsleep 15#wait for password promptexpect "*assword:"#send password send -- "$Passwd\r"sleep 5foreach cmd $commands {    set logfile [join [lrange [split $cmd] 2 end] _]    log_file -a $logfile    send -- "$cmd\r"    expect -re "admin:"    exp_sleep 8    log_file}

was not able redirect command's output to respective log file.

xxx_11 log file contains 'spawn ssh -o StrictHostKeyChecking=no $UserId@$host' output.yyy_22 log file contains 'show phone xxx 11' command output.zzz_33 log file contains 'show phone yyy 22' command output.

How to write log files in the following way:

XXX_11 log file contains 'show phone xxx 11' command outputyyy_22 log file contains 'show phone yyy 22' command outputzzz_33 log file contains 'show phone zzz 33' command output
