These options change how file names themselves are printed.
-b
’--escape
’--quoting-style=escape
’
Quote nongraphic characters in file names using alphabetic and octal backslash sequences like those used in C.
-N
’--literal
’--quoting-style=literal
’
Do not quote file names. However, with ls
nongraphic
characters are still printed as question marks if the output is a
terminal and you do not specify the --show-control-chars
option.
-q
’--hide-control-chars
’
Print question marks instead of nongraphic characters in file names.
This is the default if the output is a terminal and the program is
ls
.
-Q
’--quote-name
’--quoting-style=c
’
Enclose file names in double quotes and quote nongraphic characters as in C.
--quoting-style=word
’
Use style word
to quote file names and other strings that may
contain arbitrary characters. The word
should
be one of the following:
literal
’Output strings as-is; this is the same as the -N
or
--literal
option.
shell
’Quote strings for the shell if they contain shell metacharacters or would
cause ambiguous output.
The quoting is suitable for POSIX-compatible shells like
bash
, but it does not always work for incompatible shells
like csh
.
shell-always
’Quote strings for the shell, even if they would normally not require quoting.
shell-escape
’Like ‘shell
’, but also quoting non-printable characters using the POSIX
proposed ‘$
’ syntax suitable for most shells.
shell-escape-always
’Like ‘shell-escape
’, but quote strings even if they would
normally not require quoting.
c
’Quote strings as for C character string literals, including the
surrounding double-quote characters; this is the same as the
-Q
or --quote-name
option.
escape
’Quote strings as for C character string literals, except omit the
surrounding double-quote
characters; this is the same as the -b
or --escape
option.
clocale
’Quote strings as for C character string literals, except use surrounding quotation marks appropriate for the locale.
locale
’Quote strings as for C character string literals, except use
surrounding quotation marks appropriate for the locale, and quote
'like this'
instead of "like this"
in the default C locale. This looks nicer on many displays.
You can specify the default value of the --quoting-style
option
with the environment variable QUOTING_STYLE
. If that environment
variable is not set, the default value is ‘shell-escape
’ when the
output is a terminal, and ‘literal
’ otherwise.
--show-control-chars
’
Print nongraphic characters as-is in file names.
This is the default unless the output is a terminal and the program is
ls
.
