CLI programming :)

 

Cisco-Freak#tclsh  !!! step 1
Cisco-Freak(tcl)#foreach ping_test {  !! step 2
+>1.1.1.1
+>2.2.2.2
+>3.3.3.3
+>4.4.4.4
+>5.5.5.5
+>} { puts [exec "ping v ABG $ping_test"] }

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.4.4.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/8 ms

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 5.5.5.5, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 360/365/372 ms

Cisco-Freak(tcl)#tclquit !! step 3

[NB -> Follow steps above to execute- copy paste your shit into CLI]

So the script will look like this:

Cisco-Freak(tcl)#foreach ping_test {
+>1.1.1.1
+>2.2.2.2
+>3.3.3.3
+>4.4.4.4...
