You're kidding, right?

If you're not MacOS' versions of the most basic tools suck :/

ls -lR | awk '{if ( $1 ~ /\./) print $1; else { print $5 "\t" $8 "\t" $9}}'
Works nicely except for files with spaces... I'm getting closer!

I happened by, and thought I would offer this "brute force" method. Someone mentioned not being able to use colrm because it would whack the directory line. Then why not scoot the directory line over like so (not the prettiest command, but...):

Code:

ls -lR | grep "^\.\|^-" | sed s/^\./                                 \./ | colrm 1 33

<edit>
That sed line has 33 spaces for the replacement

Ugh... and the grep for the dash at the beginning of a line ought to have an 'l' for links or any other file-type designators you would want to include. (like grep "^\.\|^-\|^l")
</edit>

Unfortunately, I kid you not.

Code:

Domo:~/Desktop/test domo$ ls -lhR
total 12560
-rw-r--r--  1 domo  admin       6M 26 May 15:40 filename withspace.mp3
-rw-r--r--  1 domo  domo      344B 14 Jun 10:49 fileone.txt
-rw-r--r--  1 domo  domo        0B 14 Jun 10:07 filetwo.txt
drwxr-xr-x  5 domo  domo      170B 14 Jun 11:01 folderone
drwxr-xr-x  2 domo  domo       68B 14 Jun 10:08 foldertwo

./folderone:
total 0
-rw-r--r--  1 domo  domo  0B 14 Jun 10:08 image1.txt
-rw-r--r--  1 domo  domo  0B 14 Jun 10:08 image2.txt

./foldertwo:

ls -lR | awk '{if ( $1 ~ /\./) print $1; else { if ($1 == "total") print $1 " " $2; else { print $5 "\t" $8 "\t" $9}}}'
SPACES??? 'for' in awk maybe?

Dark_Helmet · 06-14-2004, 05:00 PM

I played around with mine some more and got this (sorry, the grep earlier was killing information you looks like you wanted).

Code:

ls -lR | sed "s/^\(\.\|t\)/                                 \1/" | colrm 1 33

Again, 33 spaces. Is that what you were looking for? Blank lines and "total" lines are preserved. Anyways, just thought I would mention it.

doodar · 06-14-2004, 05:09 PM

not fixed width, so colrm doesn't work...

Code:

Domo:~/Desktop/test domo$ ls -lR | sed "s/^\(\.\|t\)/                                 \1/" | colrm 1 33

6 26 May 15:40 filename withspace.mp3
4 14 Jun 10:49 fileone.txt
0 14 Jun 10:07 filetwo.txt
0 14 Jun 11:01 folderone
8 14 Jun 10:08 foldertwo



n 10:08 image1.txt
n 10:08 image2.txt

doodar · 06-14-2004, 05:10 PM

its sloppy, but:
ls -lR | awk '{if ( $1 ~ /\./) print $1; else { if ($1 == "total") print $1 " " $2; else { print $5 "\t" $6 " " $7 " " $8 "\t" $9 " " $10 " " $11 " " $12 " " $13 " " $14 " " $15 " " $16 " " $17 " " $18 " " $19 " " $20 " " $21 " " $22 " " $23 " " $24 " " $25 " " $26 " " $27 " " $28 " " }}}'

...works for files with up to 20 spaces

Dark_Helmet · 06-14-2004, 05:12 PM

Ok, from the example you had posted earlier, it looked like the column widths were the same until you got to the file sizes. My apologies. If the reason the column widths are messed up is because of tabs, then it might be possible to use sed and replace them with the appropriate number of spaces. I'm afraid that's all I can think of though.

My word, that is disgusting :)

You should install YellowDog Linux instead, or
SuSE for the Mac ;)

Haha, I know. I work in an office heavy in photoshop users. I use slackware at home.

It's been a while since I took part in this one, but the other
day I found a nice feature in awk that reminded me of your
problem :)

I noticed another potential issue with the output of your ls,
and was wondering whether on MacOS X ls also supports
ls --time-style=long-iso ... well, it's just a matter of counting,
really, and that I don't like to get some timestamps as pure
date, and others as date & time ;)

If it does, the following should make for a reasonably
"pretty" solution to your problem:

Code:

 
ls -lR | awk '{if ( $1 ~ /\./) print $1; else { if ($1 == "total") print $1 " " $2; else { printf("%12d %10s %5s ",$5,$6,$7); for(i=8; i<=NF; i++){printf("%s ",$i)};{printf("\n") }}}}'

All that just in case you're still looking for a better solution ;)

Cheers,
Tink

Wow, it's been a while since this thread...
Thanks again, but here is the beginning of the man page for ls:

Code:

NAME
     ls -- list directory contents

SYNOPSIS
     ls [-ABCFGHLPRTWZabcdfghiklmnopqrstuwx1] [file ...]

Here's the entire manpage...

Was a while indeed ...

MacOS-X ls sucks ;)

http://www2.yo-linux.com/cgi-bin/man.cgi?topic=ls

Code:

       --time-style=STYLE
              show times using style STYLE: full-iso, long-iso,  iso,  locale,
              +FORMAT

              FORMAT  is  interpreted  like  `date'; if FORMAT is FORMAT1<new-
              line>FORMAT2, FORMAT1 applies to non-recent files and FORMAT2 to
              recent  files;  if  STYLE is prefixed with `posix-', STYLE takes
              effect only outside the POSIX locale

Oh well ... but what did you think of the change to the
awk bit? :) Now your files could have any number of
spaces ;)

Cheers,
Tink

The awk string works tremendously, thank you. I actually ended up writing an Applescript to do what I was originally trying to do. It works on both System 9 and OS X. Running a unix command with your awk string runs way faster however, and I'm defintetly going to use your version for OS X.
