Bash script with expect
Dear all
Hi
I want use expect in bash so that we can not use these with each other

/bin/bash. With. /usr/bin/expect

How can use these with on script or how can call a script from other script

Code:
#!/bin/bash
clear
echo "================================== "
echo "Enter your Esxi IP"
echo "================================== "
echo -n "IP:"
read IP
clear
echo "================================== "
echo "Enter your Host Name"
echo "================================== "
echo -n "Host Name:"
read Name
clear
echo "================================== "
echo "Enter your Esxi Authentication"
echo "================================== "
echo -n "UserName:"
read user
echo -n "Password:"
read p
/usr/bin/expect   <<EOF
set force_conservative 0
set timeout 4
spawn ssh vi-admin@172.20.35.222
expect "password:"
send  "P@ssw0rd6555\r"
expect "$"
send  "echo /usr/lib/vmware-vcli/apps/general/credstore_admin.pl add >/tmp/100.txt\r"

send "exit\r"

EOF

I don't understand the question.

If you use shared keys as the ssh protocol intends you do not need to embed the password inside the script and aren't forced to use the third-party expect brute-forcing tool. You have picked the most difficult method possible as ssh intentionally prevents you from automating passwords.

Then your program becomes as simple as
Code:
ssh vi-admin@172.20.35.222 'echo /usr/lib/vmware-vcli/apps/general/credstore_admin.pl add >/tmp/100.txt'

thanks i use your script and was ok but in local server i insert a digit for example 5 but in script $p can not get 5 what is problem ?

write this but not show anything except $p when cat ll.txt file :


Code:
read p
ssh vi-admin@172.20.35.222 'echo /usr/lib/vmware-vcli/apps/general/credstore_admin.pl add --server  --username  --password "$p" > /tmp/ll.txt'

what is problem ?

The value of $p is not expanded because it was within single quotes try:

Code:
read p
ssh vi-admin@172.20.35.222 'echo /usr/lib/vmware-vcli/apps/general/credstore_admin.pl add --server  --username  --password \"'$p'\" > /tmp/ll.txt'

or, if you have a larger script or are using a lot of quoted variables, awk scripts ect. this works quite well:

Code:
ssh -T vi-admin@172.20.35.222<<EOT
    echo '/usr/lib/vmware-vcli/apps/general/credstore_admin.pl add --server  --username  --password "$p"' > /tmp/ll.txt
EOT
