1. NAME▲
find2perl - translate find command lines to Perl code
2. SYNOPSIS ▲
find2perl [paths] [predicates] | perl
3. DESCRIPTION ▲
find2perl is a little translator to convert find command lines to equivalent Perl code. The resulting code is typically 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 4 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 ) 4 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 interpretation by the shell using a backslash (just as with using find(1)).
PREDICATE1 PREDICATE2 4 True if _both_ PREDICATE1 and PREDICATE2 are true; PREDICATE2 is not evaluated if PREDICATE1 is false.
PREDICATE1 -o PREDICATE2 4 True if either one of PREDICATE1 or PREDICATE2 is true; PREDICATE2 is not evaluated if PREDICATE1 is true.
-follow 4 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 « -follow » option follows the file check option, this now applies to the symbolic link itself, i.e. an « lstat » is done.
-depth 4 Change directory traversal algorithm from breadth-first to depth-first.
-prune 4 Do not descend into the directory currently matched.
-xdev 4 Do not traverse mount points (prunes search at mount-point directories).
-name GLOB 4 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)).
-iname GLOB 4 Like « -name », but the match is case insensitive.
-path GLOB 4 Path name matches specified GLOB wildcard pattern.
-ipath GLOB 4 Like « -path », but the match is case insensitive.
-perm PERM 4 Low-order 9 bits of permission match octal value PERM.
-perm -PERM 4 The bits specified in PERM are all set in file's permissions.
-type X 4 The file's type matches perl's « -X » operator.
-fstype TYPE 4 Filesystem of current path is of type TYPE (only NFS/non-NFS distinction is implemented).
-user USER 4 True if USER is owner of file.
-group GROUP 4 True if file's group is GROUP.
-nouser 4 True if file's owner is not in password database.
-nogroup 4 True if file's group is not in group database.
-inum INUM 4 True file's inode number is INUM.
-links N 4 True if (hard) link count of file matches N (see below).
-size N 4 True if file's size matches N (see below) N is normally counted in 512-byte blocks, but a suffix of c specifies that size should be counted in characters (bytes) and a suffix of k specifies that size should be counted in 1024-byte blocks.
-atime N 4 True if last-access time of file matches N (measured in days) (see below).
-ctime N 4 True if last-changed time of file's inode matches N (measured in days, see below).
-mtime N 4 True if last-modified time of file matches N (measured in days, see below).
-newer FILE 4 True if last-modified time of file matches N.
-print 4 Print out path of file (always true). If none of « -exec », « -ls », « -print0 », or « -ok » is specified, then « -print » will be added implicitly.
-print0 4 Like -print, but terminates with \0 instead of \n.
-exec OPTIONS ; 4 exec() the arguments in OPTIONS in a subprocess; any occurrence of {} in OPTIONS will first be substituted with the path of the current file. Note that the command 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 ; 4 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 interpretation by the shell using a backslash (just as with using find(1)).
-eval EXPR 4 Has the perl script eval() the EXPR.
-ls 4 Simulates « -exec ls -dils {} ; »
-tar FILE 4 Adds current output to tar-format FILE.
-cpio FILE 4 Adds current output to old-style cpio-format FILE.
-ncpio FILE 4 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
