| 9 | .SH NAME |
| 10 | ls \- list contents of directory |
| 11 | .SH SYNOPSIS |
| 12 | .B ls |
| 13 | [ |
| 14 | .B \-1AaCcdFfgikLlqRrstu |
| 15 | ] [ file ... ] |
| 16 | .br |
| 17 | .SH DESCRIPTION |
| 18 | For each directory argument, |
| 19 | .I ls |
| 20 | lists the contents of the directory; |
| 21 | for each file argument, |
| 22 | .I ls |
| 23 | repeats its name and any other information requested. |
| 24 | By default, the output is sorted alphabetically. |
| 25 | When no argument is given, the current directory is listed. |
| 26 | When several arguments are given, |
| 27 | the arguments are first sorted appropriately, |
| 28 | but file arguments are processed |
| 29 | before directories and their contents. |
| 30 | .PP |
| 31 | The options are as follows: |
| 32 | .TP |
| 33 | .B \-1 |
| 34 | force one entry per line output format; this is the default when |
| 35 | output is not to a terminal. |
| 36 | .TP |
| 37 | .B \-A |
| 38 | List all entries except for ``.'' and ``..''. |
| 39 | Always set for the super-user. |
| 40 | .TP |
| 41 | .B \-a |
| 42 | List all entries; in the absence of this option, entries whose |
| 43 | names begin with a period |
| 44 | .RB ( . ) |
| 45 | are |
| 46 | .I not |
| 47 | listed. |
| 48 | .TP |
| 49 | .B \-C |
| 50 | force multi-column output; this is the default when output is to a terminal. |
| 51 | .TP |
| 52 | .B \-c |
| 53 | Use time when file status was last changed for sorting or printing. |
| 54 | .TP |
| 55 | .B \-d |
| 56 | If argument is a directory, list only its name; |
| 57 | often used with \fB\-l\fR to get the status of a directory. |
| 58 | .TP |
| 59 | .B \-f |
| 60 | Don't sort the output. |
| 61 | .TP |
| 62 | .B \-F |
| 63 | cause directories to be marked with a trailing `/', |
| 64 | sockets with a trailing `=', |
| 65 | symbolic links with a trailing `@', and executable |
| 66 | files with a trailing `*'. |
| 67 | .TP |
| 68 | .B \-g |
| 69 | Include the group ownership of the file in a long output. |
| 70 | .TP |
| 71 | .B \-i |
| 72 | For each file, print the i-number in the first column of the report. |
| 73 | .TP |
| 74 | .B -k |
| 75 | Modifies the |
| 76 | .I -s |
| 77 | option, causing the sizes to be reported in kilobytes. |
| 78 | .TP |
| 79 | .B \-L |
| 80 | If argument is a symbolic link, list the file or directory the link references |
| 81 | rather than the link itself. |
| 82 | .TP |
| 83 | .B \-l |
| 84 | List in long format, giving type and mode (in the format described by |
| 85 | .IR strmode (3)), |
| 86 | number of links, owner, size in bytes, and time of last modification |
| 87 | for each file. |
| 88 | If the file is a special file the size field will instead contain |
| 89 | the major and minor device numbers. |
| 90 | If the file is a symbolic link the pathname of |
| 91 | the linked-to file is printed preceded by ``\->''. |
| 92 | .TP |
| 93 | .B \-q |
| 94 | force printing of non-graphic characters in file names as |
| 95 | the character `?'; this is the default when output is to a terminal. |
| 96 | .TP |
| 97 | .B \-R |
| 98 | recursively list subdirectories encountered. |
| 99 | .TP |
| 100 | .B \-r |
| 101 | Reverse the order of sort to get reverse alphabetic |
| 102 | or oldest first as appropriate. |
| 103 | .TP |
| 104 | .B \-s |
| 105 | Display the sizes of files and directories in 512-byte blocks. |
| 106 | .TP |
| 107 | .B \-t |
| 108 | Sort by time modified (latest first) instead of |
| 109 | by name. |
| 110 | .TP |
| 111 | .B \-u |
| 112 | Use time of last access instead of last |
| 113 | modification for sorting |
| 114 | (with the \fB\-t\fP option) |
| 115 | and/or printing (with the \fB\-l\fP option). |
| 116 | .PP |
| 117 | The |
| 118 | .IR -1 , |
| 119 | .IR -C , |
| 120 | and |
| 121 | .I -l |
| 122 | options all override each other; the last one specified determines |
| 123 | the format used. |
| 124 | .PP |
| 125 | The |
| 126 | .IR -c , |
| 127 | and |
| 128 | .I -u |
| 129 | options override each other; the last one specified determines |
| 130 | the file time used. |
| 131 | .PP |
| 132 | When the sizes of the files in a directory |
| 133 | are listed, a total count of blocks, |
| 134 | including indirect blocks is printed. |
| 135 | .SH FILES |
| 136 | /etc/passwd to get user id's for |
| 137 | `ls \-l'. |
| 138 | .br |
| 139 | /etc/group to get group id's for |
| 140 | `ls \-g'. |
| 141 | .SH BUGS |
| 142 | The option setting based on whether the output is a teletype is |
| 143 | undesirable as ``ls\ \-s'' is much different than ``ls\ \-s\ |\ lpr''. |
| 144 | On the other hand, not doing this setting would make old shell scripts |
| 145 | which used |
| 146 | .I ls |
| 147 | almost certain losers. |
