FIND2PERL(1) Perl Programmers Reference Guide FIND2PERL(1)NAMEfind2perl - translate find command lines to Perl code
SYNOPSISfind2perl [paths] [predicates] | perl
DESCRIPTIONfind2perl is a little translator to convert find command
lines to equivalent Perl code. The resulting code is typ
ically faster than running find itself.
"paths" are a set of paths where find2perl will start its
searches and "predicates" are taken from the following
list.
""! PREDICATE""
Negate the sense of the following predicate. The "!"
must be passed as a distinct argument, so it may need
to be surrounded by whitespace and/or quoted from
interpretation by the shell using a backslash (just as
with using "find(1)").
""( PREDICATES )""
Group the given PREDICATES. The parentheses must be
passed as distinct arguments, so they may need to be
surrounded by whitespace and/or quoted from interpre
tation by the shell using a backslash (just as with
using "find(1)").
""PREDICATE1 PREDICATE2""
True if _both_ PREDICATE1 and PREDICATE2 are true;
PREDICATE2 is not evaluated if PREDICATE1 is false.
""PREDICATE1 -o PREDICATE2""
True if either one of PREDICATE1 or PREDICATE2 is
true; PREDICATE2 is not evaluated if PREDICATE1 is
true.
""-follow""
Follow (dereference) symlinks. The checking of file
attributes depends on the position of the "-follow"
option. If it precedes the file check option, an
"stat" is done which means the file check applies to
the file the symbolic link is pointing to. If "-fol
low" option follows the file check option, this now
applies to the symbolic link itself, i.e. an "lstat"
is done.
""-depth""
Change directory traversal algorithm from breadth-
first to depth-first.
""-prune""
Do not descend into the directory currently matched.
""-xdev""
Do not traverse mount points (prunes search at mount-
point directories).
""-name GLOB""
File name matches specified GLOB wildcard pattern.
GLOB may need to be quoted to avoid interpretation by
the shell (just as with using "find(1)").
""-perm PERM""
Low-order 9 bits of permission match octal value PERM.
""-perm -PERM""
The bits specified in PERM are all set in file's per
missions.
""-type X""
The file's type matches perl's "-X" operator.
""-fstype TYPE""
Filesystem of current path is of type TYPE (only
NFS/non-NFS distinction is implemented).
""-user USER""
True if USER is owner of file.
""-group GROUP""
True if file's group is GROUP.
""-nouser""
True if file's owner is not in password database.
""-nogroup""
True if file's group is not in group database.
""-inum INUM""
True file's inode number is INUM.
""-links N""
True if (hard) link count of file matches N (see
below).
""-size N""
True if file's size matches N (see below) N is nor
mally counted in 512-byte blocks, but a suffix of "c"
specifies that size should be counted in characters
(bytes) and a suffix of "k" specifes that size should
be counted in 1024-byte blocks.
""-atime N""
True if last-access time of file matches N (measured
in days) (see below).
""-ctime N""
True if last-changed time of file's inode matches N
(measured in days, see below).
""-mtime N""
True if last-modified time of file matches N (measured
in days, see below).
""-newer FILE""
True if last-modified time of file matches N.
""-print""
Print out path of file (always true).
""-print0""
Like -print, but terminates with \0 instead of \n.
""-exec OPTIONS ;""
exec() the arguments in OPTIONS in a subprocess; any
occurence of {} in OPTIONS will first be substituted
with the path of the current file. Note that the com
mand "rm" has been special-cased to use perl's
unlink() function instead (as an optimization). The
";" must be passed as a distinct argument, so it may
need to be surrounded by whitespace and/or quoted from
interpretation by the shell using a backslash (just as
with using "find(1)").
""-ok OPTIONS ;""
Like -exec, but first prompts user; if user's response
does not begin with a y, skip the exec. The ";" must
be passed as a distinct argument, so it may need to be
surrounded by whitespace and/or quoted from interpre
tation by the shell using a backslash (just as with
using "find(1)").
""-eval EXPR""
Has the perl script eval() the EXPR.
""-ls""
Simulates "-exec ls -dils {} ;"
""-tar FILE""
Adds current output to tar-format FILE.
""-cpio FILE""
Adds current output to old-style cpio-format FILE.
""-ncpio FILE""
Adds current output to "new"-style cpio-format FILE.
Predicates which take a numeric argument N can come in
three forms:
* N is prefixed with a +: match values greater than N
* N is prefixed with a -: match values less than N
* N is not prefixed with either + or -: match only values equal to N
