RedHat Spawn command not found!!!
Hi,
I am writing a script to automate installation of java in shell script.
Code:
#!/bin/sh
#!/usr/bin/expect
ls -la | grep jdk* | rpm -ivh ./jdk*.rpm
alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_71/bin/java 2
spawn alternatives --config java
expect "Enter to keep the current selection[+], or type selection number: "
send "2\r"

I am getting the following error while executing this script
Code:
[root@localhost ]# ./javaUpdate.sh
Preparing...                ########################################### [100%]
        package jdk-2000:1.7.0_71-fcs.i586 is already installed
./javaUpdate.sh: line 5: spawn: command not found
couldn't read file "Enter to keep the current selection[+], or type selection number: ": no such file or directory
./javaUpdate.sh: line 7: send: command not found

Spawn is working to other ssh script at the same server.
Can anyone let me why these errors are ?

Thanks Smilie

Please use code tags as required by forum rules!

spawn is NOT a shell command but an expect (which you don't run) builtin.
I don't think it "is working to other ssh script at the same server" unless you run expect in there.

Thanks for reply. it has another errors after changing it to expect as:
Code:
[root@ldapclient rncit]# cat javaUpdate.sh
#!/usr/bin/expect -f
ls -la | grep jdk* | rpm -ivh ./jdk*.rpm
alternatives --install /usr/bin/java java /usr/java/jdk1.7.0_71/bin/java 2
spawn alternatives --config java
expect "Enter to keep the current selection[+], or type selection number: "
send "2\r"

Errors

Code:
 invalid command name "ls"
    while executing
"ls -la | grep jdk* | rpm -ivh ./jdk*.rpm"
    (file "./javaUpdate.sh" line 2)

ls is a system command, as are grep and rpm. You can't mix up expect internals with system and shell commands.
Please make sure you understand the difference between shell and expect application.

Have you tried:
Code:
$ yum search jdk
# yum install java-1.8.0-openjdk

Hope this helps

NOTE: Ok i'm on fedora and might have a newer package, but otherwise its the same on any RedHat based system.

It ok! in case of new installation not in java-upgrade when you have no epel connected to internet. java is already installed to java-1.6.0 but need to upgrade this by rpm.
can you LEt me how to give input to this command automatically agianst to pattern matching /usr/java/jdk1.7.0_71/bin/java?

Code:
[root@localhost ~]# alternatives --config java

There are 3 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*  1           /usr/lib/jvm/jre-1.6.0-openjdk/bin/java
   2           /usr/lib/jvm/jre-1.5.0-gcj/bin/java
 + 3           /usr/java/jdk1.7.0_71/bin/java

Enter to keep the current selection[+], or type selection number:

Is this possible with shell ?
Thanks
