Programming :: Python - Find And Replace While Typing In Raw Input

Apr 30, 2010

I'm writing a program in Python that presents a place for the user to input one-line of text (using raw_input). I need, however, as the user types, for certain words to be replaced, even before the user hits enter.

I try to make an animation so you can see what I mean, here the word "pig" gets replaced with "sheep":
>I|
>I |
>I l|
>I li|
>I lik|
>I like|
>I like |
>I like t|
>I like to|
>I like to |
>I like to e|
>I like to ea|
>I like to eat|
>I like to eat |
>I like to eat p|
>I like to eat pi|
>I like to eat pig|
>I like to eat sheep|

Note, the user never typed "sheep", the program replaced "pig" with "sheep" as soon as they finished typing the word "pig". The user did not use "Enter". Is this at all possible in Python?

Programming :: Find And Replace Script In Bash?

Sep 28, 2010

Im looking for assistance to create a script to find and replace files.Probably best if I give you the background Our server uses a specific application which stores user data, each user data account (a folder on the server) has a file called 'Profile.xml' this file gets updated and replaced about every 30 mins similar to the fashion logrotate works i.e. Profile.xml.1 Profile.xml.2 -> .10

What we experience is that if the application crashes unexpectedly while it is doing its user profile refresh task we end up with sometimes a few hundred Profile.xml files which end up 0kb(should be around 4kb) , and our server see's these as corrupted profiles and will not see them. Our fix is to go back thru and rename the Profile.xml.1 to be Profile.xml (or sometimes up to Profile.xml.5 to Profile.xml) We want a script we can manually run to automate this process The server tree is

/mnt/array1/username/db/Profile.xml
/mnt/array2/username/db/Profile.xml
etc
etc

What we have so far is a script which finds the affected files

find /mnt/ -maxdepth 4 -name Profile.xml -size -1k

This will display a list of affected profiles, and we can append it to a text file with >>output.txt on the end.

if 'pattern' in 'location' equals '0kb' then 'cp' Profile.xml.1 Profile.xml

Programming :: Exact Text Find And Replace?

Aug 13, 2010

I have a sysctl.conf that has the following in it:

kernel.exec-shield-randomize = 1
kernel.exec-shield = 1

When I grep kernel.exec-shield I get both line, hence I keep over writing the kernel.exec-shield-randomize in my script because it finds them both for my sed commend.

How can I get an exact match with either sed/awk/grep in shell so I can do a find and replace?

Example: sed 's/^kernel.exec-shield =.*/kernel.exec-shield = 1/g' /etc/sysctl.conf will replace BOTH lines

Example: grep "^kernel.exec-shield" find both line and I want it to find only the exact line.

Software :: Applications Not Taking Typing Input?

Jul 8, 2010

I'm using an application, then suddenly, it won't take any typed input. Happens on my internal and USB keyboard (is a laptop). Happens usually to just one application at a time (I can type in other applications). The only way I see to fix it is to quit the application, and restart the application. Very bad if I have lots of work open!

Software where I have seen this problem:
firefox
gedit
gimp
save dialogs

My setup:
Debian 5.0.4
XFce
SCIM

Programming :: Multi-line Find - Replace With GnuWin32 Sed?

Apr 26, 2009

I would like to have a script that will do a search in an XML file for a specific block of XML code and replace it with a different block of XML code using the Windows build of GNU Sed 4.1.5.

Here's the text I want to find:

Code:

And here's what I want to replace it with:

Code:

There is however a lot of stuff in there that would mess up sed, and the one example from the sed FAQ (from the Sourceforge site) that looked promising and easy enough to figure out (4.23.3. Try to use a block of "literal strings") fails with this error message: sed: file blockrep.sed line 18: unterminated `s' command

Anyone got any ideas, or even an alternate program that can do this? (Preferably one that I can automate.)

Programming :: Find And Replace A String In A File Using Perl Command From Bash Script?

Feb 14, 2011

I wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.

perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";

But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.

Fedora :: Upgrade / Replace Current Python 2.5.2 On F10?

Dec 31, 2009

I have some tools that seem to have issues with Python 2.5 but are OK (on other systems) with Python 2.6. So, I was considering upgrading my Python interpreter to the current 2.6.4, but I know that in various RH distros, this was strongly discouraged. Is it OK to replace my current Python 2.5.2 on F10? If so, should that be done from source or can I do this cleanly through yum?

Programming :: Command For Find/Replace In Text Files (inc. Files In Sub-folders)?

Oct 11, 2010

I found this command that works great finding and replacing a simple string to another in files located in that folder and all sub-folders.

Code: find . -name '*.php' | xargs perl -pi -e 's/OldText/NewText/g'

The problem I have is that I need to replace a more complex string, like this: Old string: /mnt/stor6-wc2-dfw1/627896/982574/ New string: /mnt/stor8-wc2-dfw1/369587/302589/ There I don't know how to do it... since the / is what separates the old from the new strings, and the strings that I want to replace have / in it. Also, I would like to know how to specify under what folder replace the files, for example, I want that it search/replaces all files under /var/www/mysite/htdocs folder.

Programming :: Perl: Find Variable Text Between Keywords And Replace W/ "term_<variable_text>_term"?

Jul 12, 2010

I am trying to write a Perl script that can open a file, find text that appears between two identifying strings (for now, "start" and "end"), then modify that text by enclosing it between "term_" and "_term" . Since the identified strings vary, the replacement string becomes "term_$1_term". From looking at other threads in this forum I've been able to get as far as spitting out the modified terms using the following code:

open FILE, "start2.txt" || die ("Could not open file <br> $!");
$text = <FILE>;
while ($text=~ s/start (.*?) end//) {

[code]....

The problem is how to get "term_$1_term" into the file in the same while loop, which I'm guessing would be some of variant of "$text=~ s/$1/$term/;" (which doesn't work as it stands).

General :: Define A Keyboard Layout / Input Method For Ubuntu In Python?

Jun 20, 2010

defining keyboard layouts in linux (ubuntu 10.04 here). there does not seem to be any easy, graphical way to define keyboard mappings (except for keyboardlayouteditor, but frankly, i do not understand the installation description.i am using an apple aluminum keyboard with a german layout, but no matter what i do the (<>) and (^) keys are always swapped (i did manage to change the default behavior for the f1...f12 keys from multimedia back to 'ordinary', application-centric... all you have to do is add the line echo 2 > /sys/module/hid_apple/parameters/fnmode to /etc/rc.local... this is so bloody obvious i am ashamed i had to search the web for this!).

adding to my distress, i find the chinese IMEs a horror (not a single one of the many i tried does anywhere come near google pinyin for windows), and have gotten neither ibus nor scime to work in a satisfactory way for me. i find linux keyboard handling a morass. i know this must be one of the hardest problems in computer science, since this subject gets so convoluted no matter whether its on windows or in-the-browser javascript. as a linguist i am well aware of the inherent complications proper text handling poses, but looking at descriptions how to configure xkb makes building interstellar spaceships look like a cakewalk.

find a place in the system where keystrokes are recorded;read out those codes (could be scan codes or character codes) using a daemon (implemented in python; i heard you have to listen to IOCTL or somesuch); when certain code combinations appear, switch them to do what you want;applications now get to see a X where formerly the got to see a U and vice versa;profit!

Is there a place, in ubuntu / linux systems that does allow reading out keyboard codes? Is there a way to block processing of such keyboard actions until an intercepting daemon has processed them? Would such an interceptor work for a broad range of use cases? like on the command line, in a gtk app, in wine, in firefox and so on? An alternative would actually be to grok keyboardlayouteditor, so if someone could post about a readable, complete installation instruction or point out installable packages, that'd be great, too.

Software :: How To Find And Replace On All Backslashes

Ubuntu :: Find And Replace With Sed At Beginning Of A Word

Nov 15, 2010

I want to write a small script to rename a bunch of files. Their name is of the form 'long number'|'name'|'extension', for example:

52354Football_part2.flv
2353452Nice_weather_4_ducks.flv

I would like to rename these to:

Football_part2.flv
Nice_weather_4_ducks.flv

If in my script I use something like

Code:
sed s/[0-9]//g
on each file, I will get
Football_part.flv, instead of Football_part2.flv,
and
Nice_weather__ducks.flv, instead of Nice_weather_4_ducks.flv.

how to instruct sed to only remove numbers that are in the beginning of the name in a simple way?
