find : missing conjunction

I made a poor assumption that HP-UX 11 was more similar to a linux system, where find does have a -print0 option. But since you are running a system-V unix, you can use:
Code:
find . -type f \( -name '*.jsp' -o -name '*.js' \) -print | xargs grep -n chiru

which will work provided none of your file or directories contains whitespace or quotes -- see this for more information. If your files might contain whitespace or quotes, you will have to use:
Code:
find . -type f \( -name '*.jsp' -o -name '*.js' \) -print | sed -e 's/[ "'"'"']/\\&/g' | xargs grep -n chiru

to escape the separators.

Can you please explain what you mean by this?
Also, what version of perl are you running?

virt-login-shell

VIRT-LOGIN-SHELL(1)					      Virtualization Support					       VIRT-LOGIN-SHELL(1)

NAME

       virt-login-shell - tool to execute a shell within a container matching the users name

SYNOPSIS

       virt-login-shell

DESCRIPTION

       The virt-login-shell program is a setuid shell that is used to join an LXC container that matches the user's name.  If the container is not
       running, virt-login-shell will attempt to start the container.  virt-sandbox-shell is not allowed to be run by root.  Normal users will get
       added to a container that matches their username, if it exists, and they are configured in /etc/libvirt/virt-login-shell.conf.

       The basic structure of most virt-login-shell usage is:

	 virt-login-shell

OPTIONS

       -h, --help
	   Display command line help usage then exit.

       -V, --version
	   Display version information then exit.

CONFIG

       By default, virt-login-shell will execute the /bin/sh program for the user.  You can modify this behaviour by defining the shell variable
       in /etc/libvirt/virt-login-shell.conf.

       eg.  shell = [ "/bin/ksh", "--login"]

       By default no users are allowed to use virt-login-shell, if you want to allow certain users to use virt-login-shell, you need to modify the
       allowed_users variable in /etc/libvirt/virt-login-shell.conf.

       eg. allowed_users = [ "tom", "dick", "harry" ]
