sconsign - print SCons .sconsign file information SYNOPSIS
sconsign [ options... ] file [ ... ] DESCRIPTION
The sconsign command displays the contents of one or more .sconsign files specified by the user. By default, sconsign dumps the entire contents of the specified file(s). Each entry is printed in the following format: file: signature timestamp length implicit_dependency_1: signature timestamp length implicit_dependency_2: signature timestamp length action_signature [action string] None is printed in place of any missing timestamp, bsig, or csig values for any entry or any of its dependencies. If the entry has no implicit dependencies, or no build action, the lines are simply omitted. By default, sconsign assumes that any file arguments that end with a .dbm suffix contains signature entries for more than one directory (that is, was specified by the SConsignFile () function). Any file argument that does not end in .dbm is assumed to be a traditional .sconsign file containing the signature entries for a single directory. An explicit format may be specified using the -f or --file= options. OPTIONS
Various options control what information is printed and the format: -a, --act, --action Prints the build action information for all entries or the specified entries. -c, --csig Prints the content signature (csig) information for all entries or the specified entries. -d DIRECTORY, --dir=DIRECTORY When the signatures are being read from a .dbm file, or the -f dbm or --format=dbm options are used, prints information about only the signatures for entries in the specified DIRECTORY. -e ENTRY, --entry=ENTRY Prints information about only the specified ENTRY. Multiple -e options may be used, in which case information about each ENTRY is printed in the order in which the options are specified on the command line. -f FORMAT, --format=FORMAT The file(s) to be printed are in the specified FORMAT. Legal values are dbm (the DBM format used when the SConsignFile() function is used) or sconsign (the default format used for an individual .sconsign file in each directory). -h, --help Prints a help message and exits. -i, --implicit Prints the list of cached implicit dependencies for all entries or the the specified entries. --raw Prints a pretty-printed representation of the raw Python dictionary that holds build information about individual entry (both the entry itself or its implicit dependencies). An entry's build action is still printed in its usual format. -r, --readable Prints timestamps in a human-readable string, enclosed in single quotes. -t, --timestamp Prints the timestamp information for all entries or the specified entries. -v, --verbose Prints labels identifying each field being printed. ENVIRONMENT
SCONS_LIB_DIR Specifies the directory that contains the SCons Python module directory (e.g. /home/aroach/scons-src-0.01/src/engine). on the com- mand line. SEE ALSO

elfdump(1) General Commands Manual elfdump(1) NAME
elfdump - dump information contained in object files. SYNOPSIS
num] num2] name] section] num] num2] files... DESCRIPTION
takes one or more object files or libraries and dumps information about them. The following options are supported: Dumps archive headers from an archive library. Dumps the string table(s). (Modifier) Demangles C++ symbol names before printing them. This modifier is valid with and If specified with this modifier is ignored. If specified with name, the symbol whose unmangled name matches name will be printed, and its symbol name will be printed as a demangled name. Prints the .note section which contains the compilation unit dictionary and linker footprint. This option has the same effect as Prints the compilation unit dictionary of the .notes section. Prints the linker footprint of the .notes section. The linker footprint has information on the linker used to generate the file as well as the link time. (Modifier) Prints the section whose index is num. (Modifier) Prints the sections in the range 1 to num2. If used with the sections in the range num to num2 are printed. Valid with If used with only the relocations which apply to the section(s) in the range are printed. Dumps the file header (ELF header). Dumps global symbols from an archive. Dumps the section headers. (Modifier) Dumps output information in hexadecimal, octal, or decimal format, with all options. Displays the run-time interpreter path name for (usually the location of the dynamic loader and microloader). Only shared bound executables have this string. To change the setting, use the command. Prints the object dictionary for one or more executable files, if the source file was compiled with the option or linked with (PA-RISC only) option. The object dictionary entry contains the name of the object file that contributed to a particular section, the relative offset within the section, size of the object file's contribution, and attributes of the entry. Prints the CTTI section headers according to the directory member relationship. Dumps the section in shared libraries and dynamically linked program files. Prints the section, which is only created when the incremental linker is used (with the command), or when the linker option is used (which is the default), along with the compiler option, (which is NOT the default). Prints the section, which is only created when the incremental linker is used (with the command), or when the linker option is used (which is the default), along with the compiler option, (which is NOT the default). Prints the section, which is only created when the incremental linker is used (with the command), or when the linker option is used (which is the default), along with the compiler option, (which is NOT the default). (Modifier) Dumps information about the specified section or symbol name. This option is valid with and If used with name pertains to a symbol name and will only dump the symbol entry whose name matches name. If used with the other options, name pertains to a section name and will only dump the section whose name matches it. Dumps the optional headers (program headers). (Modifier) Do not print titles, with all options. (Modifier) Suppresses printing CTTI section headers. Valid with option. Dumps the relocations. Dumps the section contents. Dumps any section beginning with as a string table. (Modifier) Dumps the section specified by name. Valid with and only. (Modifier) Dumps output information in short format. Valid with the and options. Dumps the symbol table entries. (Itanium-based systems) Dumps the value of in symbol table, in addition to information dump from option. This option is useful to verify the data stored in the symbol table. Prints the symbol whose index is num. (Modifier) Prints the symbols in the range 0 to num2. If used with print the symbols in the range num to num2. Valid with Prints versioned symbols. Prints the usage menu. Prints the unwind table. (Modifier) Verifies the CTTI section headers before printing. Valid with the option. Prints the version number for EXAMPLES
