ipython colours
Yellow on white is unreadable. Adjust by:
% colors LightBG
in the ipython window. Make permanent by editing
~/.ipython/ipythonrc
If that has no effect, check IPYTHONDIR:
echo $IPYTONDIR
to check the ipython config directory is as expected.

HDD hard drive failure
To rescue:
Buy a new drive.
On a separate machine:
Create a boot usb stick. I chose unetboot for this, with ubuntu heron 64.
Download the source for dd_recover. In its directory, type, 'make'.
Copy the executable onto the usb drive.
On the injured machine:
Disconnect all irrelevant drives (reduce the chance of mistake).
Boot, with the old and new drive connected.
Establish which is the dying drive, and the new drive, by 'ls /dev/sd*'
Open a terminal, navigate to /cdrom
Execute, 'dd_recover /dev/sdbroken /dev/sdnew'
Cross fingers and wait. At 50Mb/s, a 1Tb drive will take 5 hours: best case.
When complete, replace the dying with the new drive and try to boot. Then,
partition the drive to get to the extra space. This may require booting from
the usb stick if the drive is in use. Better, would be to remove the new drive
and treat in a separate machine.
------------------------------
Another dead drive, this time an external USB HDD. It does not mount
when connected. Apparently, power was turned off during format.

suggested adding irqpoll to the kernel options on boot. I didn't, though.
Buy a new drive.
On a separate machine:
Create a boot usb stick. I chose unetboot for this, with ubuntu heron 64.
Download the source for dd_recover. In its directory, type, 'make'.
Copy the executable onto the usb drive.
On the injured machine:
Disconnect all irrelevant drives (reduce the chance of mistake).
Boot, with the old and new drive connected.
Establish which is the dying drive, and the new drive, by 'ls /dev/sd*'
Open a terminal, navigate to /cdrom
Execute, 'dd_recover /dev/sdbroken /dev/sdnew'
Cross fingers and wait. At 50Mb/s, a 1Tb drive will take 5 hours: best case.
When complete, replace the dying with the new drive and try to boot. Then,
partition the drive to get to the extra space. This may require booting from
the usb stick if the drive is in use. Better, would be to remove the new drive
and treat in a separate machine.
------------------------------
Another dead drive, this time an external USB HDD. It does not mount
when connected. Apparently, power was turned off during format.

suggested adding irqpoll to the kernel options on boot. I didn't, though.

Mass file renaming, linux!
Well, congrats to Gavbo: This has been tested and does just what was desired.
# Rename Writings.* to Index.*
for s in Writings.*; do mv $s ${s/'Writings'/'Index'}; done;
# Rename Writings.* to Index.*
for s in Writings.*; do mv $s ${s/'Writings'/'Index'}; done;
command line loop: copy file with incrementing filename and substitute text
for example:
Test the command:
for i in 0 1 2 3 4 5 6 7; do echo cp tol_b3.DAT tol_b1$i.DAT; done
Run the command:
for i in 0 1 2 3 4 5 6 7; do cp tol_b3.DAT tol_b1$i.DAT; done
Substitute parameter: This uses sed, with all the files.
To replace 'abc' with def' in file, 'xyz':
sed -e 's/abc/def/' xyz > xyz
So, to replace ''step' = 1' with ''step' = index' where index is increasing:
(note, the tmp and mv is required, as sed will wipe the file, otherwise.)
for i in 0 1 2 3 4 5 6 7;
do
sed -e "s/step' = 1/step' = $i/" tol_b1$i.DAT > tmp
mv tmp tol_b1$i.DAT
done
which becomes the following one line:
for i in 0 1 2 3 4 5 6 7; do sed -e "s/step' = 1/step' = $i/" tol_b1$i.DAT > tmp; mv tmp tol_b1$i.DAT; done
Also, sets of files being copied / renamed (according to Gavin):
for s in Writings.*; do mv $s ${s/'Writings'/'Index'}; done;
