Installation guide

• file
Reads one or more files as input, performs a series of tests on the files,
and determines their types.
• lex
Generates a C language source file that matches patterns for simple
lexical analysis of an input stream.
• lint
Checks C application files for coding that is inefficient, not portable, or
might cause errors. For example, this command finds unreachable
statements, automatic variables that are declared and not used, and
logical expressions that have a constant value.
• make
Builds up-to-date versions of application programs. The make command
updates the application program depending on whether the files used to
build the program have changed. The make command updates the
program only if the files used to build it have changed.
DIGITAL UNIX also includes the ULTRIX make command. See
Section 7.1 for information on using the ULTRIX make command.
• nm
Displays symbol table information for object files and archive files.
• odump
Displays information about an object file, archive file, or executable file.
For example, you can use odump options to display an object file’s
header, defined symbols, or program regions.
• pixie and prof and pixstats
The pixie command reads applications, partitions them into basic
blocks, and counts the execution of the basic blocks. Use the prof
command with the -pixie option to display pixie data. The
pixstats command analyzes the output from pixie. These profiling
tools are only supported with archive libraries. They cannot be used
with shared libraries. Note that the pixstats command produces
incorrect results on DIGITAL UNIX systems.
• size
Displays the number of bytes required by each section of an object file,
as well as the total number of bytes required by the object file.
• stdump
Displays detailed symbol table information for an application or object.
• strip
