capgetp - Linux

Overview

capgetp is a command-line tool used to get the permitted capability set of a process. It can be used to check the capabilities that a process is allowed to use, or to set the permitted capability set of a process. Capabilities are a mechanism for granting specific privileges to a process, such as the ability to mount filesystems or access privileged ports.

Syntax

capgetp [-v | --verbose] [-h | --help]

Options/Flags

The following options are available:

• -v, –verbose: Display the complete list of capabilities, including those that are not set.
• -h, –help: Display help and usage information.

Examples

To get the permitted capability set of the current process, run:

capgetp

To get the permitted capability set of a specific process, use the -p option followed by the process ID:

capgetp -p 1234

To set the permitted capability set of the current process, use the -S option followed by a comma-separated list of capabilities:

capgetp -S cap_sys_admin,cap_net_bind_service

Common Issues

One common issue with capgetp is that it can only be used to get or set the permitted capability set of a process. It cannot be used to get or set the effective capability set of a process. To get or set the effective capability set of a process, use the capset command.

Another common issue is that capgetp requires root privileges to run. If you try to run capgetp without root privileges, you will get an error message.

Integration

capgetp can be used with other Linux commands and tools to perform advanced tasks. For example, capgetp can be used to check the capabilities that a specific process is allowed to use before running that process. This can help to prevent security vulnerabilities.

Related Commands
