The ‘–all’ (‘-a’) option overrides this option. ‘-A’ or ‘–almost-all’: In directories, do not ignore all file names that start with ‘.’ ignore only ‘.’ and ‘.’.‘-a’ or ‘–all’: In directories, do not ignore file names that start with ‘.’.The following command options can be used: It shows the list in “long format” which includes the permissions, owner, group, size, last-modified date, number of hard links and the filename described. The “ls” command option “-a” will show all files and folders, including hidden ones. The division of options into the subsections is not absolute, since some options affect more than one aspect of ‘ls’’s operation. They are described in the subsections below within each section, options are listed alphabetically (ignoring case). If no non-option argument is specified, ‘ls’ operates on the current directory, acting as if it had been invoked with a single argument of ‘.’.īy default, the output is sorted alphabetically, according to the locale settings in effect.(1) If standard output is a terminal, the output is in columns (sorted vertically) and control characters are output as question marks otherwise, the output is listed one per line and control characters are output as-is.īecause ‘ls’ is such a fundamental program, it has accumulated many options over the years. For other non-option arguments, by default ‘ls’ lists just the file name. For non-option command-line arguments that are directories, by default ‘ls’ lists the contents of directories, not recursively, and omitting files with names beginning with ‘.’. Options and file arguments can be intermixed arbitrarily, as usual. The ‘ls’ program lists information about files (of any type, including directories).
