% ls -al | egrep '^[ld]'
It isn't the best as far as being stuck with the long format of ls,
but it does the job.

If you mean "what would be the command for listing all those files within a particular directory that are either subdirectories or symbolic links", try "ls -l | egrep '^[dl]'". If you want a recursive listing of that flavor, try "find . \( -type d -o -type l \) -print".

It is more the lack of a more powerful "ls" command what is bothering you. Solutions to this exist, e.g.: ls -l `find . \( -name . -o -prune \) -a \( -type d -o -type l \) -print` or ls -l | grep "[ld]" -- Juergen Wagner gandalf@csli.stanford.edu wagner@arisia.xerox.com

How about "ls -F", which (on BSD) marks subdirectories with a trailing "/" and symlinks with a trailing "@"? ls -F | grep '[/@]$' When you feed BSD "ls" into a pipe, it doesn't print the filenames in columns; that's good for this test but it looks lousy on the screen if there are lots of filenames. A kludge for that looks like this: ls -F | grep '[/@]$' | pr -4 -l1 -t The "-4" gives 4 columns -- adjust that, depending on the filename length. --Jerry Peek; Syracuse University Academic Computing Services; Syracuse, NY jdpeek@rodan.acs.syr.edu, jdpeek@suvm.bitnet +1 315 443-3995

It does the former on S5 as well, although since vanilla S5 doesn't have symlinks (unless they've snuck it into 3.2), it doesn't do the latter. I hope anybody whose S5 *does* have them added it to "ls" that way; SunOS's S5 "ls" ("/usr/5bin/ls") does that, and I expect S5R4's to do so as well.

Well, only if a directory or symbolic link shows up as the *last* file in a line. The other solution I saw, with ls -F | grep '[/@]$' | pr -5 -l1 -t is probably the only way to do it in one line with existing tools. (You need to adjust the "5" by trial-and-error.) Another bizarre solution is: ls -CFd `find . '(' -type d -o -type l ')' -print` which produces roughly the same list, if you don't mind getting subdirectories as well. And, I dislike having to 'ls' a file that 'find' already saw, but that's life. Just a UN*X Hacker, -- ***** PLEASE IGNORE THE ADDRESS IN THE HEADER ***** /=Randal L.

Yeah, but what about symbolic links to directorys? They also come out with trailing `/'s. Better would be trailing `\'s, to distinguish them. BTW, Sun's `ls -lR' works dirrerently than 4.3 BSD. One follows symbolic links and the other does not. Why the change? My example above may be wrong. Perhaps it is the behaviour of `ls -R' that exhibits different behaviour. In any case, something changed. Root Boy Jim is what I am Are you what you are or what?
