Hi Sebastian,

Ok, I've changed the grub menu.lst file. After the reboot I will write

this is the kernel interface to set the brightness.
I have it, but running
cho 2 /sys/class/backlight/acpi_video0/brightness
has no effect in the display brightness.
CONFIG_BACKLIGHT_LCD_SUPPORT
is the appropriate kernel config category to look at in recent kernels.
Yes, that variable is set.
BTW which kernel are you using?
2.6.27-r2
No doubt: the first dimms the videocard output, the latter the LCD.
I didn't know the reasons for this missmatch, thanks a lot for this
brief but useful explanation.
You can use xev to see which keycode is emmitted and then look in your
desktop environment if this is match with some action.
In fact, Fn + dimming keys produces output. Now, to do something
useful, I need to know how to dim the light of the LCD.
Well. it should be somehow applicable, because it is rather generic.
I don't know how to replace this line
echo level ${LEVEL} /proc/acpi/ibm/brightness
I have a file
/proc/acpi/video/C14B/C160/brightness
whose contents look like
levels: 100 51 30 37 44 51 58 65 72 79 86 93 100
current: 72
I did some echoes to that file, but no luck so far :(

For instance, if I'm dropping columns 6 12 from a 20 column wide data set, then I'm dropping 6 12 from all N lines. This is where using cut after the line is built is difficult as I'm forced to figure out a list like 6,12,26,32,46,52, etc. Easy to make a mistake doing that. If I could say something like Drop 6 12 from all rows, and 1 2 from all rows higher than the first that make up this new line then that would be great. That's a lot to ask though. D1,T1,A1,B1,C1,D1, D2,T2,A2,B2,C2,D2, D3,T3,A3,B3,C3,D3, D4,T4,A4,B4,C4,D4, D5,T5,A5,B5,C5,D5, In the data above if I drop column A, then I drop it for all rows. (For instance, A contains 0 and isn't necessary, etc.) Assuming 3 wide I'd get D1,T1,B1,C1,D1,B2,C2,D2,B3,C3,D3 D2,T2,B2,C2,D2,B3,C3,D3,B4,C4,D4 D3,T3,B3,C3,D3,B4,C4,D4,B5,C5,D5 Making that completely flexible - where I can drop 4 or 5 random columns - is probably a bit too much work. On the other hand maybe sending it to cut as part of the whole process, line by lone or something, is more reasonable? I don't know. The current dropcol variable drops fields from the beginning of line. Doing that for arbitrary columns can be done, but requires an array where to save the numbers of the columns to drop. So, in my understanding this is what we want to accomplish so far: given an input of the form D1,T1,a1,b1,c1,d1,...,R1 D2,T2,a2,b2,c2,d2,...,R2 D3,T3,a3,b3,c3,d3,...,R3 D4,T4,a4,b4,c4,d4,...,R4 D5,T5,a5,b5,c5,d5,...,R5 (the ... mean that an arbitrary number of columns can follow) You want to group lines by n at a time, keeping the D and T column from the first line of each group, and keeping the R column from the last line of the group, so for example with n=3 we would have: D1,T1,a1,b1,c1,d1,...a2,b2,c2,d2,...a3,b3,c3,d3,...R3 D1,T1,a2,b2,c2,d2,...a3,b3,c3,d3,...a4,b4,c4,d4,...R4 D1,T1,a3,b3,c3,d3,...a4,b4,c4,d4,...a5,b5,c5,d5,...R5 (and you're right, that produces an output that is roughly n times the size of the original file) Now, in addition to that, you also want to drop an arbitrary number of columns in the a,b,c... group.

something like

Perfectly correct for all the data rows.
For the header I now see that we have a slightly harder job. What we'd
need to do is read the first line of the file, duplicate it N times,
and then drop the same columns as we drop in the rows. The problem is
that now I have the same header value for N columns which won't make
sense to the tool that uses this data. If we could read the header and
then automatically postpend the number N to each duplicated name. (or
some string like _N)
So in the last example the header would be something like
D,T,a,b,c,d,...,R
in the original file, and would become
D,T,a_1,b_1,c_1,d_1,...a_2,b_2,c_2,d_2,...a_3,b_3,c_3,d_3,...R
and
D,T,a_1,d_1,...a_2,d_2,...a_3,d_3,...R
respectively for the two sample outputs above.
Maybe better would be a separate small program to do the header part
and then this program could read that header and make it the first
line of the output file. My worry is that when this data file becomes
very large - say 1GB or more of data - I probably cannot open the file

kindly building would just read it, cut out columns, and put it at the
start of the new large file.
Does that make sense?
Maybe, but while we're at it my personal preference would be to just add
header handling to the existing program. Here's the revised code (also
cleaned up a bit and more structured):
# returns a ,a1,b1,c1,.. line
# drops unwanted columns
function do_line(num) {
line=
for(j=3;jNF;j++)
if(!((j-2) in dc)){line=line OFS $j (num0?_num:)}
return line
}
# dcols is a string like '2,3,4,7' with a comma separated values list of
# the columns to drop (first data column after date/time is column 1
# here)
BEGIN {FS=OFS=,
t=split(dcols,tmp,/,/)
for(i=1;i=t;i++)dc[tmp[i]]
}
# process the header
NR==1{
l=$1 OFS $2;
for(i=1;i=n;i++)l=l do_line(i)
l=l OFS $NF
print l
}
NR=2{
for(i=1;in;i++){
s[i]=s[i+1]
dt[i]=dt[i+1]
}
dt[n]=$1 OFS $2
s[n]=do_line(-1)
if(NR=n+1){
l=dt[1]
for(i=1;i=n;i++)l=l s[i]
l=l OFS $NF
print l
}
}'
I think two examples are enough here to demonstrate how it works (blank
lines between commands added for clarity - remember first line is header
line):
$ cat file.csv
D,T,a,b,c,d,R
D1,T1,a1,b1,c1,d1,R1

$ awk -v n=3 -v dcols='1,3' -f program.awk file.csv
D,T,b_1,d_1,b_2,d_2,b_3,d_3,R
D1,T1,b1,d1,b2,d2,b3,d3,R3
D2,T2,b2,d2,b3,d3,b4,d4,R4
D3,T3,b3,d3,b4,d4,b5,d5,R5
D4,T4,b4,d4,b5,d5,b6,d6,R6
The program still assumes that first two columns and last column must be
excluded from the general processing, and just prepended and appended to
the output lines. That can be changed though.

D1,T1,a3,b3,c3,d3,...a4,b4,c4,d4,...a5,b5,c5,d5,...R5
(and you're right, that produces an output that is roughly n times
the size of the original file)
Now, in addition to that, you also want to drop an arbitrary number
of columns in the a,b,c... group. So for example, you want to drop
columns 2 and 3 (b and c in the example), so you'd end up with
something like
D1,T1,a1,d1,...a2,d2,...a3,d3,...R3
D1,T1,a2,d2,...a3,d3,...a4,d4,...R4
D1,T1,a3,d3,...a4,d4,...a5,d5,...R5
Please confirm that my understanding is correct, so I can come up
with some code to do that.
Perfectly correct for all the data rows.
For the header I now see that we have a slightly harder job. What we'd
need to do is read the first line of the file, duplicate it N times,
and then drop the same columns as we drop in the rows. The problem is
that now I have the same header value for N columns which won't make
sense to the tool that uses this data. If we could read the header and
then automatically postpend the number N to each duplicated name. (or
some string like _N)
So in the last example the header would be something like
D,T,a,b,c,d,...,R
in the original file, and would become
D,T,a_1,b_1,c_1,d_1,...a_2,b_2,c_2,d_2,...a_3,b_3,c_3,d_3,...R
and
D,T,a_1,d_1,...a_2,d_2,...a_3,d_3,...R
respectively for the two sample outputs above.
Maybe better would be a separate small program to do the header part
and then this program could read that header and make it the first
line of the output file. My worry is that when this data file becomes
very large - say 1GB or more of data - I probably cannot open the file
with vi to edit the header. Better if I could put the header in it's
own file. That file would be 1 line long. I could check it for the
name edits, make sure it's right, and then the program you are so
kindly building would just read it, cut out columns, and put it at the
start of the new large file.
Does that make sense?
Maybe, but while we're at it my personal preference would be to just add
header handling to the existing program. Here's the revised code (also
cleaned up a bit and more structured):
# returns a ,a1,b1,c1,.. line
# drops unwanted columns
function do_line(num) {
line=
for(j=3;jNF;j++)
if(!((j-2) in dc)){line=line OFS $j (num0?_num:)}
return line
}
# dcols is a string like '2,3,4,7' with a comma separated values list of
# the columns to drop (first data column after date/time is column 1
# here)
BEGIN {FS=OFS=,
t=split(dcols,tmp,/,/)
for(i=1;i=t;i++)dc[tmp[i]]
}
# process the header
NR==1{
l=$1 OFS $2;
for(i=1;i=n;i++)l=l do_line(i)
l=l OFS $NF
print l
}
NR=2{
for(i=1;in;i++){
s[i]=s[i+1]
dt[i]=dt[i+1]
}
dt[n]=$1 OFS $2
s[n]=do_line(-1)
if(NR=n+1){
l=dt[1]
for(i=1;i=n;i++)l=l s[i]
l=l OFS $NF
print l
}
}'
I think two examples are enough here to demonstrate how it works (blank
lines between commands added for clarity - remember first line is header
line):
$ cat file.csv
D,T,a,b,c,d,R
D1,T1,a1,b1,c1,d1,R1
D2,T2,a2,b2,c2,d2,R2
D3,T3,a3,b3,c3,d3,R3
D4,T4,a4,b4,c4,d4,R4
D5,T5,a5,b5,c5,d5,R5
D6,T6,a6,b6,c6,d6,R6
$ awk -v n=3 -f program.awk file.csv
D,T,a_1,b_1,c_1,d_1,a_2,b_2,c_2,d_2,a_3,b_3,c_3,d_3,R
D1,T1,a1,b1,c1,d1,a2,b2,c2,d2,a3,b3,c3,d3,R3
D2,T2,a2,b2,c2,d2,a3,b3,c3,d3,a4,b4,c4,d4,R4
D3,T3,a3,b3,c3,d3,a4,b4,c4,d4,a5,b5,c5,d5,R5
D4,T4,a4,b4,c4,d4,a5,b5,c5,d5,a6,b6,c6,d6,R6
$ awk -v n=3 -v dcols='1,3' -f program.awk file.csv
D,T,b_1,d_1,b_2,d_2,b_3,d_3,R
D1,T1,b1,d1,b2,d2,b3,d3,R3
D2,T2,b2,d2,b3,d3,b4,d4,R4
D3,T3,b3,d3,b4,d4,b5,d5,R5
D4,T4,b4,d4,b5,d5,b6,d6,R6
The program still assumes that first two columns and last column must be
excluded from the general processing, and just prepended and appended to
the output lines. That can be changed though.
Excellent! Worked identically for me once I removed an extra single
quote after the last brace that somehow crept into your copy/paste in
this email. Really good stuff.

Re: [gentoo-user] How to dim the display brightness
Hello Damian,
and take a look if /sys/class/backlight/acpi_video0/ is present:
On an IBM T61 i have acpi_video1 too. Video0 represents the vga/dvi output
where video1 represents the LCD.
Also have a look on max_brightness on this dirs for the maximum value.
You can use xev to see which keycode is emmitted and then look in your
desktop environment if this is match with some action.
In fact, Fn + dimming keys produces output. Now, to do something
useful, I need to know how to dim the light of the LCD.
As workarround you could switch to a console (Ctrl+Alt+F1) and try to dim with
your fn+ keys.
Well. it should be somehow applicable, because it is rather generic.
I don't know how to replace this line
echo level ${LEVEL} /proc/acpi/ibm/brightness
I have a file
/proc/acpi/video/C14B/C160/brightness
whose contents look like
levels: 100 51 30 37 44 51 58 65 72 79 86 93 100
current: 72
Be careful to touch the right (video-)output. In /proc/acpi/video i have two
devices: VID and VID1. VID1 references to my LCD.

Re: [gentoo-user] OT -- superuser file manager access to remote via ssh with no root login?

Have a bunch of random renaming to do on that machine though, so would like to point and click for a change. Is this possible? No GUI libs on the remote machine... I was thinking sshfs, but since I can't login directly as root, is there some other way? I can see several solutions, as well: 1. Restrict root auth to public key and bind public key to your IP only ( 'from=IP ssh-dss ...' in authorized_hosts, or tcp wrappers ). 2. Create login like 'somerandomuser' (you can actually use a hash here, if you're security-crazed) and disallow root auth from pam, not sshd. 3. Since it sounds like you have no need to do it repeatedly, why not open root and do the stuff? Provided you don't have '123' as password. While I think security is overally a good thing, making some aspects of it a pain in the ass is what I just can't understand in people: it may take ages to pick the root password (provided you have right anti-brute daemon installed), but they will make their lives miserable over it, while leaving the same passwords typed in the terminals and written on paper scraps lying on the desk, not to mention a lot of more obvious things. -- Mike Kazantsev // fraggod.net signature.asc Description: PGP signature

Is OO really so stupid that it makes you add by hand for each user an extension spelling library from /usr/lib/openoffice/extension/install to get a spelling checker to work? Is this anyway to run a business? OK, solved. Working. I don't get it.

Go to ~/.kde/share/apps/kmail/mail/folder/cur, and delete the actual file. grep can help you find it even if only by identifying the files that isn't it. Then delete the relevant index files in ~/.kde/share/apps/kmail/mail. Your inbox for example is called .inbox.index.* and there will be three of them. Restart kmail, it will rebuild it's indexes and all will be well. (With KDE-4, change those paths to ~/.kde4/ I suppose I could delete my home directory, create a new one and import kmail's stuff from the old to the new, together with other applications' stuff, but I don't know any way to import filters, and anyway it's an awful fag.
