9 sconsign [options...] file [...]
10
12 The sconsign command displays the contents of one or more .sconsign
13 files specified by the user.
14
15 By default, sconsign dumps the entire contents of the specified
16 file(s). Each entry is printed in the following format:
17
18 file: signature timestamp length implicit_dependency_1: signature
19 timestamp length implicit_dependency_2: signature timestamp length
20 action_signature [action string]
21
22 None is printed in place of any missing timestamp, bsig, or csig values
23 for any entry or any of its dependencies. If the entry has no implicit
24 dependencies, or no build action, the lines are simply omitted.
25
26 By default, sconsign assumes that any file arguments that end with a
27 .dbm suffix contains signature entries for more than one directory
28 (that is, was specified by the SConsignFile () function). Any file
29 argument that does not end in .dbm is assumed to be a traditional
30 .sconsign file containing the signature entries for a single directory.
31 An explicit format may be specified using the -f or --file= options.
32
34 Various options control what information is printed and the format:
35
36 -a, --act, --action
37 Prints the build action information for all entries or the
38 specified entries.
39
40 -c, --csig
41 Prints the content signature (csig) information for all entries or
42 the specified entries.
43
44 -d DIRECTORY, --dir=DIRECTORY
45 When the signatures are being read from a .dbm file, or the -f dbm
46 or --format=dbm options are used, prints information about only the
47 signatures for entries in the specified DIRECTORY.
48
49 -e ENTRY, --entry=ENTRY
50 Prints information about only the specified ENTRY. Multiple -e
51 options may be used, in which case information about each ENTRY is
52 printed in the order in which the options are specified on the
53 command line.
54
55 -f FORMAT, --format=FORMAT
56 The file(s) to be printed are in the specified FORMAT. Legal values
57 are dbm (the DBM format used when the SConsignFile() function is
58 used) or sconsign (the default format used for an individual
59 .sconsign file in each directory).
60
61 -h, --help
62 Prints a help message and exits.
63
64 -i, --implicit
65 Prints the list of cached implicit dependencies for all entries or
66 the the specified entries.
67
68 --raw
69 Prints a pretty-printed representation of the raw Python dictionary
70 that holds build information about individual entry (both the entry
71 itself or its implicit dependencies). An entry's build action is
72 still printed in its usual format.
73
74 -r, --readable
75 Prints timestamps in a human-readable string, enclosed in single
76 quotes.
77
78 -t, --timestamp
79 Prints the timestamp information for all entries or the specified
80 entries.
81
82 -v, --verbose
83 Prints labels identifying each field being printed.
84
86 SCONS_LIB_DIR
87 Specifies the directory that contains the SCons Python module
88 directory (e.g. /home/aroach/scons-src-0.01/src/engine). on the
89 command line.
