1.22 aaron 47: .Nm
1.1 deraadt 48: recursively descends the directory tree for each

1.22 aaron 52: (composed of the
53: .Dq primaries
54: and
1.52 otto 55: .Dq operators
1.22 aaron 56: listed below) in terms
1.12 millert 57: of each file in the tree.
1.34 deraadt 58: In the absence of an expression,
59: .Ic -print
60: is assumed.
1.66 jmc 61: If an expression is given,
62: but none of the primaries
63: .Ic -exec ,
64: .Ic -ls ,
65: .Ic -ok ,
66: .Ic -print ,
67: or
68: .Ic -print0
1.67 jmc 69: are specified, the given expression is effectively replaced by
1.66 jmc 70: .Cm \&( Ar given expression Cm \&)
71: .Ic -print .
1.1 deraadt 72: .Pp
73: The options are as follows:
74: .Bl -tag -width Ds
75: .It Fl d
1.16 aaron 76: Causes
1.22 aaron 77: .Nm
1.45 jmc 78: to visit directories in post-order
79: i.e. all entries in a directory will be acted on before the directory itself.
1.1 deraadt 80: By default,
1.22 aaron 81: .Nm
1.45 jmc 82: visits directories in pre-order i.e. before their contents.
1.43 jaredy 83: .It Fl f Ar path
1.16 aaron 84: Specifies a file hierarchy for
1.22 aaron 85: .Nm
1.1 deraadt 86: to traverse.
1.52 otto 87: File hierarchies may be specified without the
88: .Fl f
89: option if they are given immediately after any other options.
1.35 millert 90: .It Fl H
91: Causes the file information and file type (see
92: .Xr stat 2 )
93: returned for each symbolic link encountered on the command line to be
94: those of the file referenced by the link, not the link itself.
95: If the referenced file does not exist, the file information and type will
96: be for the link itself.
97: File information of all symbolic links not on
98: the command line is that of the link itself.
1.1 deraadt 99: .It Fl h
1.35 millert 100: An alias for the
101: .Fl L
102: option.
1.37 david 103: This option exists for backwards compatibility.
1.35 millert 104: .It Fl L
1.16 aaron 105: Causes the file information and file type (see
1.22 aaron 106: .Xr stat 2 )
1.1 deraadt 107: returned for each symbolic link to be those of the file referenced by the
108: link, not the link itself.
109: If the referenced file does not exist, the file information and type will
110: be for the link itself.
111: .It Fl X
1.16 aaron 112: Permit
1.1 deraadt 113: .Nm
114: to be safely used in conjunction with
115: .Xr xargs 1 .
116: If a file name contains any of the delimiting characters used by
117: .Xr xargs ,
118: a diagnostic message is displayed on standard error, and the file
119: is skipped.
1.22 aaron 120: The delimiting characters include single
121: .Pq Ql '
122: and double
123: .Pq Ql \&"
124: quotes, backslash
125: .Pq Ql \e ,
126: space, tab, and newline

1.79 schwarze 131: instead.
1.1 deraadt 132: .It Fl x
1.16 aaron 133: Prevents
1.22 aaron 134: .Nm
1.1 deraadt 135: from descending into directories that have a device number different
136: than that of the file from which the descent began.
137: .El
1.76 schwarze 138: .Pp
139: It is not an error to specify more than one of
140: the mutually exclusive options
141: .Fl H
142: and
143: .Fl L .
144: Where more than one of these options is specified,
145: the last option given overrides the others.

1.63 otto 206: .Pp
207: Since

550: .Sh STANDARDS
551: The
1.22 aaron 552: .Nm
1.68 jmc 553: utility is compliant with the
1.72 jmc 554: .St -p1003.1-2008
1.68 jmc 555: specification.
1.1 deraadt 556: .Pp
1.55 jmc 557: The options
558: .Op Fl dfhXx
559: and primaries
1.18 deraadt 560: .Ic -amin ,

1.1 deraadt 575: and
576: .Ic -print0
1.68 jmc 577: are extensions to that specification.
1.27 deraadt 578: The
579: .Ic -iname
1.57 otto 580: primary was inspired by GNU find.
1.1 deraadt 581: .Pp
582: Historically, the
583: .Fl d ,
1.26 aaron 584: .Fl H ,
1.1 deraadt 585: and
586: .Fl x
1.14 deraadt 587: options were implemented using the primaries
588: .Ic -depth ,
589: .Ic -follow ,
590: and
591: .Ic -xdev .
1.1 deraadt 592: These primaries always evaluated to true.
593: As they were really global variables that took effect before the traversal
594: began, some legal expressions could have unexpected results.
1.22 aaron 595: An example is the expression
1.54 jmc 596: .Dq -print -o -depth .
1.22 aaron 597: As
1.54 jmc 598: .Cm -print
1.22 aaron 599: always evaluates to true, the standard order of evaluation
600: implies that
1.54 jmc 601: .Cm -depth
1.22 aaron 602: would never be evaluated.
1.1 deraadt 603: This is not the case.
604: .Pp
1.22 aaron 605: The operator
606: .Cm -or
607: was implemented as
1.54 jmc 608: .Cm -o ,
1.22 aaron 609: and the operator
610: .Cm -and
611: was implemented as
1.54 jmc 612: .Cm -a .
1.1 deraadt 613: .Pp
614: Historic implementations of the
615: .Ic -exec
616: and
617: .Ic -ok
1.22 aaron 618: primaries did not replace the string
619: .Qq {}
620: in the utility name or the
1.1 deraadt 621: utility arguments if it had preceding or following non-whitespace characters.
622: This version replaces it no matter where in the utility name or arguments
623: it appears.
1.30 aaron 624: .Sh HISTORY
625: A
626: .Nm
627: command appeared in
628: .At v1 .
1.50 jmc 629: .Sh CAVEATS
1.1 deraadt 630: The special characters used by
1.22 aaron 631: .Nm
1.1 deraadt 632: are also special characters to many shell programs.
1.22 aaron 633: In particular, the characters
634: .Ql * ,
1.78 schwarze 635: .Ql \&[ ,
1.22 aaron 636: .Ql \&] ,
1.40 jmc 637: .Ql \&? ,
1.78 schwarze 638: .Ql \&( ,
1.22 aaron 639: .Ql \&) ,
1.40 jmc 640: .Ql \&! ,
1.22 aaron 641: .Ql \e ,
642: and
643: .Ql \&;
644: may have to be escaped from the shell.
1.79 schwarze 645: .Pp
646: Passing the output of
647: .Nm
648: to other programs requires some care:
649: .Pp
650: .Dl "$ find . -name \e*.jpg | xargs rm"
651: or
652: .Dl "$ rm `find . -name \e*.jpg`"
653: .Pp
654: would, given files
655: .Dq important\ .jpg
656: and
657: .Dq important ,
658: remove
659: .Dq important .
660: Use the
661: .Ic -print0
662: or
663: .Ic -exec
664: primaries instead.
1.1 deraadt 665: .Pp
666: As there is no delimiter separating options and file names or file
667: names and the
668: .Ar expression ,
1.22 aaron 669: it is difficult to specify files named
670: .Dq -xdev
671: or
1.65 jmc 672: .Sq \&! .
1.1 deraadt 673: These problems are handled by the
674: .Fl f
675: option and the
676: .Xr getopt 3
1.65 jmc 677: .Sq --
1.22 aaron 678: construct.
