passing passwd to a command in a script
Hi All,

I have a requirment..
I need to pass a registry password to a command.. Actually when the command executed in the script, it will return some warnings first, then after it'll ask password like below,

Code:
 
$ cleartool rmtag -vob -all <vob_name>
Warnings: ------------------
Registry password:
$

I tried like below,
Code:
$ cleartool rmtag -vob -all <vob_name> <<eof
$pwd
eof

Here, 'pwd' variable is set with the registry password. But no luck.. it's still asking the passwd. I guess, it's because of that it's returning some warnings.. but i cant ignore those warnings...
Can anyone please provide the way to pass the passwd in this scenario?

Thank in advance..

Regards,
VRN

See if you could supply the password from a file.

Code:
$ 
$ # show the contents of the script "cleartool.sh"
$ cat -n cleartool.sh
     1    #!/bin/bash
     2    echo "Warnings: this is warning # 1"
     3    echo "Warnings: this is warning # 2"
     4    echo "Warnings: this is warning # 3"
     5    printf "Registry password: "
     6    read PSWD
     7    echo "Your registry password is $PSWD"
     8    ## And now the rest of the code...
$ 
$ # show the contents of the response file "myregistrypassword"
$ cat -n myregistrypassword
     1    PASSWORD_FROM_FILE
$ 
$ # run "cleartool.sh" and enter password from stdin
$ ./cleartool.sh rmtag -vob -all vobname
Warnings: this is warning # 1
Warnings: this is warning # 2
Warnings: this is warning # 3
Registry password: PASSWORD_FROM_STDIN
Your registry password is PASSWORD_FROM_STDIN
$ 
$ 
$ # run "cleartool.sh" and supply the password from the response file
$ ./cleartool.sh rmtag -vob -all vobname < myregistrypassword
Warnings: this is warning # 1
Warnings: this is warning # 2
Warnings: this is warning # 3
Registry password: Your registry password is PASSWORD_FROM_FILE
$

Hi tyler_durden,

Thank you for your reply..

I tried to pass the passwd from a file also... but no luck.. it's still asking the passwd.. I used the same way for passing the passwd when using `sudo su command`, it worked.. But it's not working for this command only,

And one more thing is we have stored the passwd in a hidden zip file, when we redirect the passwd as input to this command, it's unable to take the passwd..

Code:
$ cleartool rmtag -vob -all <vob_name> < .rgy_pwd.gz
Cleartool: Warnings: ---------------------------------
Registry passwd:  
## Here, it's asking passwd again even we provided it through file
$

I tried the same with normal file also (.rgy_pwd), it did not worked.. Smilie

Can you please advice on this..?

Thanks in advance..

Regards,
VRN..

Of course it won't work in this manner, because you never supplied your correct password. What you did supply was a stream of bytes from that gzipped file. That's not your password.

No idea about this. But I guess it doesn't hurt to ask - is your file ".rgy_pwd" an ASCII text file ? Or did you do a "mv .rgy_pwd.gz .rgy_pwd" ? That is, if you do a "cat .rgy_pwd" on your Terminal prompt, then you should be able to see your password as clear text.

If all the checks are done and if it still doesn't work, then I'd suggest you try the Expect language. See your man page for details and examples, or check the Expect website and FAQ.
