     WALK(1)                                                   WALK(1)

          walk - walk a path

          walk [ -dftxu ] [ -n mind,maxd ] [ -e statfmt ] [ name ... ]

          Walk recursively descends any directory arguments, printing
          the name of each file on a separate line.  When no arguments
          are given, the working directory is assumed.  Non-directory
          arguments are checked for existence, then printed, if so.

          Options are:

          -d   Print only directories.

          -f   Print only non-directories.

          -t   Print a file only if it has the temporary flag set.

          -x   Print a file only if it has any executable bits set.

          -u   Unbuffered output.

          -n min,max
               Set the inclusive range of depths for filtering in
               results.  Both min and max are optional.

          -e statfmt
               Setting the statfmt string allows specifying the data
               walk should print.  It takes a string of characters,
               each corresponding to some piece of information about
               the file being traversed, and prints them separated by

          The statfmt characters are as follows:

          U  owner name (uid)
          G  group name (gid)
          M  name of last user to modify (muid)
          a  last access time (atime)
          m  last modification time (mtime)
          n  final path element (name)
          p  path
          q  qid path.version.type (see stat(2))
          s  size in bytes
          x  permissions
          D  server device
          T  server type (kernel device rune)

     WALK(1)                                                   WALK(1)

          The default statfmt is simply, p.

          List files in a directory, sorted by modification time.

               walk -femp catpics | sort -n | sed 's/^[^ ]+ //'

          Print the size and path of files (excluding dirs) in the
          working directory.

               walk -fn1 -esp


          ls(1), du(1)

          Statfmt character `x' displays permissions as an integer.

          Manipulating ifs is a nuisance.

          File names are assumed to not contain newlines.

          Correct invocation requires too much thought.

          Walk first appeared in 9front (March, 2019).
