LS(1) LS(1) NAME ls - list contents of directory SYNOPSIS ls [ -acdfgilqrstu1ACLFR ] name ... DESCRIPTION For each directory argument, _l_s lists the contents of the directory; for each file argument, _l_s repeats its name and any other information requested. By default, the output is sorted alphabetically. When no argument is given, the current directory is listed. When several argu‐ ments are given, the arguments are first sorted appropriately, but file arguments are processed before directories and their contents. There are a large number of options: -l List in long format, giving mode, number of links, owner, size in bytes, and time of last modification for each file. (See below.) If the file is a special file the size field will instead contain the major and minor device numbers. If the file is a symbolic link the pathname of the linked-to file is printed preceded by ‘‘->’’. -g Include the group ownership of the file in a long output. -t Sort by time modified (latest first) instead of by name. -a List all entries; in the absence of this option, entries whose names begin with a period (.) are _n_o_t listed. -s Give size in kilobytes of each file. -d If argument is a directory, list only its name; often used with -l to get the status of a directory. -L If argument is a symbolic link, list the file or directory the link references rather than the link itself. -r Reverse the order of sort to get reverse alphabetic or oldest first as appropriate. -u Use time of last access instead of last modification for sorting (with the -t option) and/or printing (with the -l option). -c Use time of file creation for sorting or printing. -i For each file, print the i-number in the first column of the report. -f Force each argument to be interpreted as a directory and list the name found in each slot. This option turns off -l, -t, -s, and -r, and turns on -a; the order is the order in which entries appear in the directory. -F cause directories to be marked with a trailing ‘/’, sockets with a trailing ‘=’, symbolic links with a trailing ‘@’, and exe‐ cutable files with a trailing ‘*’. -R recursively list subdirectories encountered. -1 force one entry per line output format; this is the default when output is not to a terminal. -C force multi-column output; this is the default when output is to a terminal. -q force printing of non-graphic characters in file names as the character ‘?’; this is the default when output is to a terminal. The mode printed under the -l option contains 11 characters which are interpreted as follows: the first character is d if the entry is a directory; b if the entry is a block-type special file; c if the entry is a character-type special file; l if the entry is a symbolic link; s if the entry is a socket, or - if the entry is a plain file. The next 9 characters are interpreted as three sets of three bits each. The first set refers to owner permissions; the next refers to permis‐ sions to others in the same user-group; and the last to all others. Within each set the three characters indicate permission respectively to read, to write, or to execute the file as a program. For a direc‐ tory, ‘execute’ permission is interpreted to mean permission to search the directory. The permissions are indicated as follows: r if the file is readable; w if the file is writable; x if the file is executable; - if the indicated permission is not granted. The group-execute permission character is given as s if the file has the set-group-id bit set; likewise the user-execute permission charac‐ ter is given as s if the file has the set-user-id bit set. The last character of the mode (normally ‘x’ or ‘-’) is t if the 1000 bit of the mode is on. See _c_h_m_o_d(1) for the meaning of this mode. When the sizes of the files in a directory are listed, a total count of blocks, including indirect blocks is printed. FILES /etc/passwd to get user id’s for ‘ls -l’. /etc/group to get group id’s for ‘ls -g’. BUGS Newline and tab are considered printing characters in file names. The output device is assumed to be 80 columns wide. The option setting based on whether the output is a teletype is unde‐ sirable as ‘‘ls -s’’ is much different than ‘‘ls -s | lpr’’. On the other hand, not doing this setting would make old shell scripts which used _l_s almost certain losers. 3rd Berkeley Distribution May 12, 1986 LS(1)
