70 .fi
72 .SH DESCRIPTION
73 .sp
74 .LP
75 In the first synopsis form, the \fBgetconf\fR utility writes to the standard
76 output the value of the variable specified by \fIsystem_var\fR, in accordance
77 with \fIspecification\fR if the \fB-v\fR option is used.
78 .sp
79 .LP
80 In the second synopsis form, \fBgetconf\fR writes to the standard output the
81 value of the variable specified by \fIpath_var\fR for the path specified by
82 \fIpathname\fR, in accordance with \fIspecification\fR if the \fB-v\fR option
83 is used.
84 .sp
85 .LP
86 In the third synopsis form, \fBconfig\fR writes to the standard output the
87 names of the current system configuration variables.
88 .sp
89 .LP
90 The value of each configuration variable is determined as if it were obtained
91 by calling the function from which it is defined to be available. The value
92 reflects conditions in the current operating environment.
93 .SS "ksh93"
94 .sp
95 .LP
96 The \fBgetconf\fR built-in in \fBksh93\fR is associated with the \fB/bin\fR and
97 \fB/usr/bin\fR paths. It is invoked when \fBgetconf\fR is executed without a
98 pathname prefix and the pathname search finds a \fB/bin/getconf\fR or
99 \fB/usr/bin/getconf\fR executable.
100 .sp
101 .LP
102 \fBgetconf\fR displays the system configuration value for \fIname\fR. If
103 \fIname\fR is a filesystem specific variable, the value is determined relative
104 to path, or, the current directory, if path is omitted. If \fIvalue\fR is
105 specified, \fBgetconf\fR attempts to change the process local value to
106 \fIvalue\fR. \fB-\fR can be used in place of path when it is not relevant. Only
107 writable variables can be set. \fBreadonly\fR variables cannot be changed.
108 .sp
109 .LP
110 The current value for \fIname\fR is written to the standard output. If
111 \fIname\fR is valid but undefined, \fBundefined\fR is written to the standard
112 output. If \fIname\fR is invalid or an error occurs in determining its value, a
113 diagnostic is written to standard error and \fBgetconf\fR exits with a
114 \fBnon-zero\fR exit status.
115 .sp
116 .LP
117 More than one variable can be set or queried by providing the \fIname path
118 value\fR 3-tuple for each variable, specifying \fB-\fR for value when querying.
119 .sp
120 .LP
121 If no operands are specified, all known variables are written in
122 \fIname\fR\fB=\fR\fIvalue\fR form to the standard output, one per line. Only
123 one of \fB--call\fR, \fB--name\fR or \fB--standard\fR can be specified.

595 \fBExample 3 \fRDealing with Unspecified Results
596 .sp
597 .LP
598 This example shows how to deal more carefully with results that might be
599 unspecified:
601 .sp
602 .in +2
603 .nf
604 \fBif value=$(getconf PATH_MAX /usr); then
605 if [ "$value" = "undefined" ]; then
606 echo PATH_MAX in /usr is infinite.
607 else
608 echo PATH_MAX in /usr is $value.
609 fi
610 else
611 echo Error in getconf.
612 fi\fR
613 .fi
614 .in -2
616 .sp
617 .LP
618 For example:
620 .sp
621 .in +2
622 .nf
623 \fBsysconf(_SC_POSIX_C_BIND);\fR
624 .fi
625 .in -2
627 .sp
628 .LP
629 and
631 .sp
632 .in +2
633 .nf
634 \fBsystem("getconf POSIX2_C_BIND");\fR
635 .fi
636 .in -2
638 .sp

640 in a C program could give different answers. The \fBsysconf\fR call supplies a
641 value that corresponds to the conditions when the program was either compiled
642 or executed, depending on the implementation. The \fBsystem\fR call to
643 \fBgetconf\fR always supplies a value corresponding to conditions when the
644 program is executed.
646 .SH ENVIRONMENT VARIABLES
647 .sp
648 .LP
649 See \fBenviron\fR(5) for descriptions of the following environment variables
650 that affect the execution of \fBgetconf\fR: \fBLANG\fR, \fBLC_ALL\fR,
651 \fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
652 .sp
653 .LP
654 The following environment variable is supported by the \fBksh93\fR built-in
655 \fBgetconf\fR command:
656 .sp
657 .ne 2
658 .na
659 \fB\fB_AST_FEATURES\fR\fR
660 .ad
661 .RS 17n
662 Local writable values that are different from the default are stored in the
663 \fB_AST_FEATURES\fR environment variable. The \fB_AST_FEATURES\fR value is a
664 space-separated list of \fIname path value\fR 3-tuples, where \fIname\fR is the
665 system configuration name, \fIpath\fR is the corresponding path, \fB-\fR if no
666 path is applicable, and \fIvalue\fR is the system configuration value.
