UNUSUAL FILENAMES
Many of the actions of find result in the printing of data which
is under the control of other users. This includes file names,
sizes, modification times and so forth. File names are a
potential problem since they can contain any character except
`\0' and `/'. Unusual characters in file names can do unexpected
and often undesirable things to your terminal (for example,
changing the settings of your function keys on some terminals).
Unusual characters are handled differently by various actions, as
described below.
-print0, -fprint0
Always print the exact filename, unchanged, even if the
output is going to a terminal.
-ls, -fls
Unusual characters are always escaped. White space,
backslash, and double quote characters are printed using
C-style escaping (for example `\f', `\"'). Other unusual
characters are printed using an octal escape. Other
printable characters (for -ls and -fls these are the
characters between octal 041 and 0176) are printed as-is.
-printf, -fprintf
If the output is not going to a terminal, it is printed
as-is. Otherwise, the result depends on which directive
is in use. The directives %D, %F, %g, %G, %H, %Y, and %y
expand to values which are not under control of files'
owners, and so are printed as-is. The directives %a, %b,
%c, %d, %i, %k, %m, %M, %n, %s, %t, %u and %U have values
which are under the control of files' owners but which
cannot be used to send arbitrary data to the terminal, and
so these are printed as-is. The directives %f, %h, %l, %p
and %P are quoted. This quoting is performed in the same
way as for GNU ls. This is not the same quoting mechanism
as the one used for -ls and -fls. If you are able to
decide what format to use for the output of find then it
is normally better to use `\0' as a terminator than to use
newline, as file names can contain white space and newline
characters. The setting of the LC_CTYPE environment
variable is used to determine which characters need to be
quoted.
-print, -fprint
Quoting is handled in the same way as for -printf and
-fprintf. If you are using find in a script or in a
situation where the matched files might have arbitrary
names, you should consider using -print0 instead of
-print.
The -ok and -okdir actions print the current filename as-is.
This may change in a future release.
