lsdev - list device drivers in the system SYNOPSIS
driver | class] block_major] char_major] major] [major ...] DESCRIPTION
The command lists, one pair per line, the major device numbers and driver names of device drivers configured into the system and available for invocation via special files. A in either the block or character column means that a major number does not exist for that type. If no arguments are specified, lists all drivers configured into the system. If the option is specified, will not print a heading. This option may be useful when the output of will be used by another program. The and options are used to select specific device drivers for output. If more than one option is specified, all drivers that match the criteria specified by those options will be listed. These search options are divided into two types: name search keys (the and options) and major number search keys (the and options). If both types of options are present, only entries that match both types are printed. The same type of option may appear more than once on the command line with each occurrence providing an ORing effect of that search type. The and options may not be specified at the same time. The ability to process major arguments is provided for compatibility and functions like the option. Options List device drivers that match class. List device drivers with the name driver. List device drivers with a block major number of block_major. List device drivers with a character major number of char_major. List device drivers with either a character major number or block major equal to major. DIAGNOSTICS
The and options may not be specified at the same time. A major number is malformed or out of range. EXAMPLES
To output entries for all drivers in the class: To output entries that are in the class that have either a block or character major number of To get the character major number of into a shell environment variable: WARNINGS
Some device drivers available from the system may be intended for use by other drivers. Attempting to use them directly from a special file may produce unexpected results. A driver may be listed even when the hardware requiring the driver is not present. Attempts to access a driver without the corresponding hardware will fail. only lists drivers that are configured into the currently executing kernel. For a complete list of available drivers, please run (see sam(1M). DEPENDENCIES
Since relies on the device driver information provided in a routine, may not list drivers installed by other means. AUTHOR

autopush - manage system database of automatically pushed STREAMS modules SYNOPSIS
file major minor major minor DESCRIPTION
manages the system database that is used for automatic configuration of STREAMS devices. The command is used in three different ways as dictated by the and command-line options described below. Options recognizes the following command-line options and arguments: Using the configuration information contained in file, load the system database with the names of the STREAMS devices and a list of modules to use for each device. When a device is subsequently opened, the HP-UX STREAMS subsystem pushes the modules onto the stream for the device. If appears as a file argument, uses the standard input. file must contain one or more lines of at least four fields separated by a space as shown below: major minor lastminor module1 module2 ... moduleN The first field major can be either an integer or a device name. The device name is the name for the device used in the master file. The next two fields are integers. If minor is set to -1, then all minor devices for the specified major are configured and lastminor is ignored. If lastminor is 0, then only a single minor device is configured. To configure a range of minor devices for a major device, minor must be less then lastminor. The remaining field(s) list one or more module names. Each module is pushed in the order specified. A maximum of eight modules can be pushed. Any text after a # character in file is treated as a comment for that line only. This option is also used to restore device configuration information previously removed by However, when used in such a manner, the entire database is restored, not just the information that was previously removed. Display current configuration information from the system database for the STREAMS device specified by the major device number (or device name for the device from the master file) and minor number. If a range of minors has been previously configured then returns the configuration information for the first minor in the range, in addition to other information. Remove configuration information from the system database for the STREAMS device specified by the major device number (or device name for the device from the master file and minor number. Removal is performed on the database only, not on the original configuration file. Therefore, the original configuration can be restored by using the file option. To permanently exclude a STREAMS device from the database, its information must be removed from the configuration file. If minor matches the first minor of a previously configured range then removes the configuration information for the entire configured range. EXAMPLES
If the file contains: Then will cause and to be pushed whenever major device is opened, and and to be pushed for the first six opens of device This next example lists information about the stream for major device and its minor device FILES
