i have expect script ssh runs on host a, remotes host b, runs bash script b on host b, append output of script b file on host a. after running expect script, appended contents desire, duplicated. instance, if desired output "abc", i'm getting "abcabc". run timestamp duplicate same original.
please see expect script below:
#!/usr/bin/expect set ip ip set user "user" set password "password" set first " " spawn ssh $user@$ip /path/to/script/b/scriptb.sh expect { -re "(^abc)|(^password)" set variable $expect_out(buffer) set first [cut -c1-3 $variable] } if {"$first" == "abc"} { send "123" send "$password\r"; } else { send "$password\r" } expect -re "(?s)-{30}\r\n(.*?)-{30}" puts $expect_out(0,string) my hypothesis expect_out(buffer) has 2x out , 2nd expect -re matching output twice. tried using unset expect_out(buffer) unsuccessfully. played positioning of second expect -re , puts statement if-statement no avail. apologize if fix simple have spent many hours on forums looking it. ideas appreciated.
regards,
alan
fixed duplication issue; see updated code below:
expect { -re "(?s)-{30}\r\n(.*?)-{30}"
{puts $expect_out(0,string) } }
