how to get removed perforce binary files in /opt/perforce directory

Perforce requires at least two executables: the Perforce service (p4d on Unix, p4s.exe on Windows), and at least one Perforce application (such as p4 on UNIX, or p4.exe on Windows).

• Helix Core (P4D) Server

• Helix Command-Line Client (P4)

There is a lengthy list of prerequisites. Did you follow an installation procedure like this: “p4search perforce application installation and configuration Guide in Linux“.

You shouldn’t get that message, instead you should see this:

apt-get install helix-p4d

Read the documentation for installation at: “Installing and Upgrading the Server“.

“The package update commands with apt-get or yum do not complete the process of updating your Perforce service. Packages for Linux simplify only certain steps of that process.

Updating packages without completing the rest of the update process leaves your Perforce service in a precarious state. Make sure to read and understand the entire process before updating any packages.”.

You need to:

1. Configure the Perforce package repository.

2. Import the Perforce package signing key.

3. Install the appropriate Perforce service package.

4. Run the post-installation configuration script.

See the link above (“Installing and Upgrading the Server“) for complete details.
