One of expect parameter processing

One of expect parameter processing

Expect is a very powerful script, although the online resources are very classic, but very few, I put my own test script to paste, only for reference

2. #! / usr/bin/expect- F
   
4. 
   
6. Proc Help {} {
   
8. Puts {usage: <ivie_ip> [-P <password>] [cmd] }
   
10. }
    
12. 
    
14. If {$argc<1} {help ; Exit}
    
16. Set IP [ lindex $argv 0 ]
    
18. 
    
20. Set Password Rootroot
    
22. Set cmd ""
    
24. For {set I 1} {$i<$argc} {incr i 1} {
    
26. set M [lindex $argv $i]
    
28. Switch $m {
    
30. "-P" { if {$argc<3} {help ; exit 1 }
    
32. Set Password [lindex $argv [expr 1+$i ]]
    
34. INCR I 1
    
36. } default { puts "MM: $m"
    
38. lappend cmd $m
    
40. }
    
42. }
    
44. }
    
46. 
    
48. 
    
50. Puts "$ip-P $password $cmd"

I also like to use loops and case processing when I deal with Bash, which is simple and operable.
There are options behind switch:-exact mode,-glob mode,-regexp mode, default representation-glob mode. The-exact method is the exact match, and the matching method of the-glob mode is the same as the string Match command, and the-regexp way is the matching way of the regular expression.
