Question : Silmulate keystrokes in bash script

Hi experts,

I was wondering if someone could help me out with a bash script.

I have script that simply does an scp

scp *.js [email protected]:/

Is there a way to add the password info and enter key to the bash script so I don't have enter it everytime I run the script?

Thanks!

Hi DanRaposo,

I was checking in my linux box and as "scp" does not provide an option to put the password, I can suggest you to use: "expect".

I created a very simple script that you can use, check below:
===========================================================================
#!/usr/bin/expect -f

set timeout -1
spawn scp test_file.txt root@localhost:/
match_max 100000
expect -exact "root@localhost's password: "
send -- "passxxword\r"
expect eof
===========================================================================

Above I put my script, and for yours would be something like:
===========================================================================
#!/usr/bin/expect -f

set timeout -1
spawn scp *.js [email protected]:/
match_max 100000
expect -exact "[email protected]'s password: "
send -- "passxxword\r"
expect eof
===========================================================================

The scripts above are really simple and will not handle if you have a problem during the execution of "scp" like the "problem" below:
===========================================================================
The autenticity of host 'Hostname or Ip(ip address)' can't be established.
RSA Key fingerprint is xxxxxxxxxxxxxx.
Are you sure you want to continue connecting (yes/no)?
===========================================================================

You can change the script to whatever you need and if you are not familiar with "expect", the "autoexpect" command can help you, just: "man autoexpect".

I hope it helps you. =0)
