You don't need Tcl to do this for IOS. You could use an EEM applet. For example, to run those commands every day every five minutes of the 2 o'clock hour, you can use:
event manager applet automated-cli
event timer cron cron-entry "*/5 14 * * *"
action 1.0 cli command "enable"
action 2.0 cli command "show clock | redirect flash:debug.txt"
action 3.0 cli command "show interface | redirect flash:debug.txt"
