this is insane!
I've run the same command many times (at least I thought so).
Never mind, it works as expected.
Thanks

I have a few .tex files generated with html2latex. They have some extra \\ that generate error with pdflatex, so I would like to get rid of them.
This

I thought this was a very trivial thing, but I see it is not. devtakh's solutiong gives me the same result I had with sed, but that gives columns of different width.
aigles' solution seems to be...

Ok, it seems I'm getting there. Telling explicitly the width of the wider (wider than a tab) column, I get an aligned table.
BEGIN {
FS=","
}
{printf "%s\t%-40s\t%s\n", $1,$2,$3}
But isn't...

no, sorry again, it works, for some mistyping an extra '}" was in the script, so it did not work.
So, finally it works.
Thank you again.

something like this:
Header one
Header two
Header three
col1 col2 col3
short datavery long data data

no, sorry, it is still not right, now the 'š' goes to the very end of the sorting:
aaa&ccc&ddd
aaa&bbb&ccc
aaa&aaa&bbb
bbc&aaa&aaa
cab&&
lmn&bbb&aaa
mmn&aaa&ccc
saš&&
sss&&aaa
tuaa&&...

I've googled a lot on this, but could not fine a simple one-liner to do this.
I have a .csv file that looks like this:
Header one
Header two
Header three
col1,col2,col3
short data, very long...

I have perl 5.8.8 on unix
Works great! I did not know you have to tell perl to use utf8.
Thanks a lot!

well, I'm not a programmer, so I don't know if I'm able to define a custom locale right now, but of course I'm willing to learn if there's no other option. But isn't the line:
$in =~...

In another thread (field separator in Perl) I nearly solved my sorting problem and I finally understood the Schwartzian transform especially thank to KevinADC. After that I've found out that the...

ok kevinadc, thanks a lot for you time, you've been of great help!
;)

No, sorry, the original code has 'ū', what I wanted to ask is why you put 'ū' in the first and 'u' in the second.
$in =~ tr<aeiouū>
<aeiouu>;
And also wanted to ask, if I change this
...

Yes, actually, it is something I wanted to ask, because putting 'ū' in the left side would not work, but it does work like this (with two "normal" 'u' . Why is that?

Cool! With this code for example:
use strict;
use warnings;
open (_file_, "< /home/sw/zza") or die "Failed to read file : $! ";
my @not_sorted = <_file_>;
sub normalize {
my @in = @_;
...

Thanks a lot, I haven't had time to try it this day, I'm way too busy, but what does this mean:

I had to add this because otherwise Perl would not sort proerly "u" and "ū"

would it look like this? I did not try it yet.
map {chomp; [$_,normalize((split(/\&/))[0,1,2])]} @not_sorted;

Now I understand.
Although I don't need it right now, what if I wanted to sort by second column or third ect.? And why does Perl by defalut store only the first column as [1], and trips away the...

Thank you KevinADC, but I still cannot fully understand, and especially, quirkasaurus seems to be at least in part right. If I use [1] in the sort line everything goes fine, but if I use this:
use...

does this mean that the sort line will always have [1] or that it should be one number higher than the map line? eg. map [0] sort [1]; map [1] sort [2]

I'm starting to understand.
But please explain me the use of [1] and [0]:
sort{ $a->[1] cmp $b->[1]}
map {chomp; [$_,normalize((split(/\&/))[0])]} @not_sorted;
I find it a bit...

:(

I take everything back, it still does not work. I tried to change [1] to [2] to see if it sees the "&", but I got this:

Use of uninitialized value in string comparison (cmp) at zs line 14,...

I've finally got the thing to work. Thank you all.
Here's the code.
use strict;
use warnings;
open (_file_, "< path-to-file") or die "Failed to read file : $! ";
my @not_sorted = <_file_>;...

Thank you again. For some reason, I didn't even think of custom sorting in my database (postgres), I'll check it out. But since I have to do some changes on the file when it comes out, I thought to...

Thank you all. To tell the truth, I'm getting quite confused. I think I have to do some serious reading of the man pages, because I still cannot figure out how to make this split work with my posted...
