Examples Configure a login script
This example defines a login script that waits for a login prompt and then
supplies a login name, and waits for a password prompt and then supplies
a password. The commands to define the login script are:
#> set script name=log1 s1=”P2[ogin:]2 S10 T4”
#> set script name=log1 s2=”P1 M{user-ejm\r} S1 [sword:]3 T4”
#> set script name=log1 s3=”M{my-p-word\r} G5”
#> set script name=log1 s4=”E{login failed} G-”
#> set script name=log1 s5=”E{login complete} G+”
Actions performed by the script:
• In stanza S1:
— P2 means “pause for 2 seconds before executing the rest of the
script.”
— [ogin:] indicates the string to wait for.
— 2 is the stanza to jump to when the string is received.
— S10 T4 means “wait up to 10 seconds for the string “ogin:” . If the
string does not appear in that time, jump to stanza 4.”

stanza to jump to when the string is received.
