10.1.7 Formatting the file names

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Do not quote file names.

`-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 output names. The word should be one of the following:
`literal'
Output names as-is; this is the same as the `-N' or `--literal' option.
`shell'
Quote names for the shell if they contain shell metacharacters or would cause ambiguous output.
`shell-always'
Quote names for the shell, even if they would normally not require quoting.
`c'
Quote names as for a C language string; this is the same as the `-Q' or `--quote-name' option.
`escape'
Quote as with `c' except omit the surrounding double-quote characters; this is the same as the `-b' or `--escape' option.
`clocale'
Quote as with `c' except use quotation marks appropriate for the locale.
`locale'
Like `clocale', but 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 `literal', but this default may change to `shell' in a future version of this package.

`--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.
