I am writing to ask if anyone has done a command for "lc".
For those not "in the know" about "lc", this little command
list all directories and then all files at a the given node
of your file system.
For instance on my system at the office, I can do
% lc
Directories:
alpha beta comments gamma
Files:
EXAMPLE0.ARC EXAMPLE2.ARC autoboot.arc gu_start gulam.g
gulamfix.arc ljd_bugs.arc
and for many purposes it is more convenient than the nearest "ls"
equivalent:
% ls -F
EXAMPLE0.ARC autoboot.arc gamma/ gulamfix.arc
EXAMPLE2.ARC beta/ gu_start ljd_bugs.arc
alpha/ comments/ gulam.g

It seems that your `lc' is non-standard with respect to System V; that's where it came from. On my Unix(tm) Box I have the alias: alias lf 'lc -F' which produces your `ls -F'. Ls -F tells you what's executable or not, usually :-]. Under gulam I use a similar alias. Have fun, -- Ralph P.

The One True "lc" predates V7; it was invented at the University of Waterloo under V6 (maybe earlier). The 4BSD version has been posted to comp.sources.unix. On Xenix, lc is a link to ls, and is effectively an alias for "ls -C". This is probably a Xenixism, based on a Berkeleyism. Why would anyone want their files sorted down instead of across?

As far as I know, -C is not to discern between sorted down or sorted across, but to force multiple column output. 'ls' and 'ls -C' give exactly the same result (when connected to a terminal) on my system (Ultrix 2.0, which is a Berkeleyism 8-). Remember that 'ls' is a very old Unix program; it tries to be smart: when standard output is a terminal you get automagically multiple columns (and sorted down), when not the filenames each appear on one line; try f.i. 'ls|more'. Nowadays that would be considered a kludge, but since 'ls' is that old, changing it could perhaps break other programs (notably shell scripts). So if you want multiple columns through the pipe, do it ala 'ls -C|more'. If your experience with -C is different, your system is certainly different from BSD. |Why would anyone want their files sorted down instead of across? That's not so unreasonable; telephone books are also organized that way. In fact it is much easier scanning a vertical list than a horizontal one (of course your opinion may differ ...). The only time I don't like this is when a column is longer than the screen (but why shouldn't scrolling be sidewards instead of downwards ...). Leo.

I think that "lc" pre-dates V6, even. I believe it was written in the early 70s, shortly after the Math Faculty acquired a machine with a GCOS operation system. It was out the the frustration of having to deal with a couple of miserable "cata" and "catl" commands that "lc" was born, and was one of the first of a new breed of system commands installed on that system. The command was written in "B", (a pre-cursor to "C"). When the Math Faculty acquired a UNIX system, the "B" code was quickly translated to "C". Today, many users on Honeywell and Honeywell-Bull machines running GCOS operating system use the "lc" command, along with other software developed and written at Waterloo. Those who must use that hardware, but who do not have the benefit of this software, suffer under undue hardship.

It is, in system 5 jargon, equivalent to ls -C. It forces ls to produce multi-column output with the entries sorted down the column (as opposed to ls -x which sorts across). Some system 5s come with lc just to humor the XENIX users - ENIX is an example. I don't have my 386 5.3.2 manual here but it may have been added by ATT in that release just to humor people but I can promise you it isn't standard in release 5.3.0 from ATT. The solution of course is to get a complete set of our pocket references on all flavors of UNIX so you can play mix and match games :-). -- Phil Hughes, SSC, Inc. P.O.

Because "lc" is a nice command to have on a command line interpreter. In my first posting, I gave an example that showed what was wanted. Your example (not repeated here) shows the right stuff. "lc" is not specific to unix, as I stated in an earlier posting, but for some folks, it has been ported there. Those who have "lc" aliased to "ls -C" are missing something, if they do not know about the good stuff are culturally deprived. Too bad.

Lc was originally written in 'B' and ran on a honeywell at Waterloo because the catalogue listing commands, like most of the software that honeywell produced, was rather 'quaint'. (how about 'ACCESS MF foobar' to change the file attributes... blech) Needless to say, its been ported quite a bit.

The One True lc (that is, Waterloo lc) has the advantages of separating files by type and printing dotfiles: % lc / Directories: bin dev etc lib lost+found mnt once operator tmp u usr Files: .profile boot boot- dos xenix xenix- xenix.880922 For exploring the file system, lc is superior to ls. For shell scripts, lc is all but useless. Thus lc is the antithesis of proper UNIX tools. Even so, it is a good bet that a clone of lc can be found on any machine that a Waterloo-raised UNIX zealot uses. Accept no substitutes.

I've already sent off the source code for Unix to LJDickey, and I think that he is working on a port. Shouldn't be a problem unless it uses very unusual Unix libraries, but since I ported it from BSD to V several years ago that is unlikely.
