UNIX for Advanced & Expert Users

Hello,

I want to automate the process of importing a SSL certificate name *.cer to cacerts through perl script. both the certificates belong to same folder.

The usual way of doing it is by executing the below command which imports the key name certnew.cer to cacerts in the same folder.

keytool -import -alias antipodes -file certnew.cer -keystore ./cacerts

Enter keystore password:
REEnter keystore password:

After this command is executed the user will be prompted for password twice similar to above. if possible I want to allow user to specify the password in an external text file from where its will be imported and entered (this is secondary though).

Any help with a code snippet or direction to resource will be appreciated.

Thank you.

Wait, you want to automate it, then you are talking about user interaction, which one is true ? If user has to enter the pass, storing it in plain file would be security risk, give the user a chance to enter it with "<STDIN>. Else, you can use "print <<EOM; password password EOM" blocks.

Thats is true . But I am more interested in the first part. Automatically execute the command . How would i do that?

The basic idea is to write a perl script which executes a lengthy linux command.

Never mind I got it
