Hello, here is a creeping feature for ls. I prefer to see the directories listed first, sorted separately from the files. I added a new sort flag, -Y or --sort=dirext, that sorts by extension, with directories 'smallest', no extension next smallest, and sorted by filename within same extensions. Thus any extension on a directory is ignored. I am pretty sure this is the right thing, as directories don't tend to have meaningful extensions, and it makes hidden directories behave correctly.
I notice that QNX has this ability, but it uses the flag -v and is a standalone option (with any sort, it puts the directories first). http://qdn.qnx.com/support/docs/neutrino/utilities/l/ls.html Please let me know if this is useful or should be improved upon. flip >>>>>>>>>>>>>>>>>>>>> Example: <<<<<<<<<<<<<<<<<<<<<<<<< ~$ ls -Xa ###### OLD ###### bin/ .bash_logout .ICEauthority .rhosts config/ .bash_profile .kde/ .sawmill/ Desktop/ .bashrc .kderc .screenrc friction/ .dir_colors dead.letter .ssh/ mail/ .emacs .addressbook.lu .wallpaper/ nsmail/ .enlightenment/ .Mathematica/ .Xauthority pub/ .fullcircle/ .mc/ .Xdefaults wallpaper@ .gnome/ .mozilla/ .xinitrc zips/ .gnome-desktop/ .netscape/ .Xkeymaprc ./ .gnome-help-browser/ .pinerc .xsession ../ .gnome_private/ .plan .addressbook .gtkrc .profile .bash_history .history .promptrc ~$ ls -Ya ###### NEW ###### ./ mail/ .bash_history .plan ../ .Mathematica/ .bash_logout .profile bin/ .mc/ .bash_profile .promptrc config/ .mozilla/ .bashrc .rhosts Desktop/ .netscape/ .dir_colors .screenrc .enlightenment/ nsmail/ .emacs .Xauthority friction/ pub/ .gtkrc .Xdefaults .fullcircle/ .sawmill/ .history .xinitrc .gnome/ .ssh/ .ICEauthority .Xkeymaprc .gnome-desktop/ .wallpaper/ .kderc .xsession .gnome-help-browser/ zips/ dead.letter .gnome_private/ wallpaper@ .addressbook.lu .kde/ .addressbook .pinerc >>>>>>>>>>>>>>>>>>>>>>> Begin Patch <<<<<<<<<<<<<<<<<<<<<<<<<< --- ls.old.c Sun Apr 29 04:42:47 2001 +++ ls.c Fri Oct 19 16:18:17 2001 @@ -293,6 +293,10 @@ const struct fileinfo *file2)); static int rev_cmp_extension PARAMS ((const struct fileinfo *file2, const struct fileinfo *file1)); +static int compare_dirext PARAMS ((const struct fileinfo *file1, + const struct fileinfo *file2)); +static int rev_cmp_dirext PARAMS ((const struct fileinfo *file2, + const struct fileinfo *file1)); static int compare_version PARAMS ((const struct fileinfo *file1, const struct fileinfo *file2)); static int rev_cmp_version PARAMS ((const struct fileinfo *file2, @@ -429,6 +433,7 @@ sort_none, /* -U */ sort_name, /* default */ sort_extension, /* -X */ + sort_dirext, /* -Y */ sort_time, /* -t */ sort_size, /* -S */ sort_version /* -v */ @@ -720,12 +725,12 @@ static char const *const sort_args[] = { - "none", "time", "size", "extension", "version", 0 + "none", "time", "size", "extension", "dirext", "version", 0 }; static enum sort_type const sort_types[] = { - sort_none, sort_time, sort_size, sort_extension, sort_version + sort_none, sort_time, sort_size, sort_extension, sort_dirext, sort_version }; static char const *const time_args[] = @@ -1076,7 +1081,7 @@ } while ((c = getopt_long (argc, argv, - "abcdfghiklmnopqrstuvw:xABCDFGHI:LNQRST:UX1", + "abcdfghiklmnopqrstuvw:xABCDFGHI:LNQRST:UXY1", long_options, NULL)) != -1) { switch (c) @@ -1268,6 +1273,11 @@ sort_type_specified = 1; break; + case 'Y': + sort_type = sort_dirext; + sort_type_specified = 1; + break; + case '1': /* -1 has no effect after -l. */ if (format != long_format) @@ -2163,6 +2173,9 @@ case sort_extension: func = sort_reverse ? rev_cmp_extension : compare_extension; break; + case sort_dirext: + func = sort_reverse ? rev_cmp_dirext : compare_dirext; + break; case sort_size: func = sort_reverse ? rev_cmp_size : compare_size; break; @@ -2317,6 +2330,51 @@ return cmp; } +/* Compare file extensions.
