How I can delete in VIM all text from current line to end of file?

Finding all files containing a text string on Linux

I'm trying to find a way to scan my entire Linux system for all files containing a specific string of text. Just to clarify, I'm looking for text within the file, not in the file name.

When I was looking up how to do this, I came across this solution twice:

find / -type f -exec grep -H 'text-to-find-here' {} \;

However, it doesn't work. It seems to display every single file in the system.

Is this close to the proper way to do it? If not, how should I? This ability to find text strings in files would be extraordinary useful for me for some programming projects I'm doing.

MySQL: Large VARCHAR vs. TEXT?

I've got a messages table in MySQL which records messages between users. Apart from the typical ids and message types (all integer types) I need to save the actual message text as either VARCHAR or TEXT. I'm setting a front-end limit of 3000 characters which means the messages would never be inserted into the db as longer than this.

Is there a rationale for going with either VARCHAR(3000) or TEXT? There's something about just writing VARCHAR(3000) that feels somewhat counter-intuitive. I've been through other similar posts on Stack Overflow but would be good to get views specific to this type of common message storing.

Any help would be appreciated. Thanks.

CSS text-overflow in a table cell?

I want to use CSS text-overflow in a table cell, such that if the text is too long to fit on one line, it will clip with an ellipsis instead of wrapping to multiple lines. Is this possible?

I tried this:

td {
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
}

But the white-space: nowrap seems to make the text (and its cell) continually expand out to the right, pushing the total width of the table beyond the width of its container. Without it, however, the text continues to wrap to multiple lines when it hits the edge of the cell.

Android: combining text & image on a Button or ImageButton

I'm trying to have an image (as the background) on a button and add dynamically, depending on what's happening during run-time, some text above/over the image.

If I use ImageButton I don't even have the possibility to add text. If I use Button I can add text but only define an image with android:drawableBottom and similar XML attributes as defined here.

However these attributes only combine text & image in x- and y-dimensions, meaning I can draw an image around my text, but not below/under my text (with the z-axis defined as coming out of the display).

Any suggestions on how to do this? One idea would be to either extend Button or ImageButton and override the draw()-method. But with my current level of knowledge I don't really know how to do this (2D rendering). Maybe someone with more experience knows a solution or at least some pointers to start?

How can I detect the encoding/codepage of a text file

In our application, we receive text files (.txt, .csv, etc.) from diverse sources. When reading, these files sometimes contain garbage, because the files where created in a different/unknown codepage.

Is there a way to (automatically) detect the codepage of a text file?

The detectEncodingFromByteOrderMarks, on the StreamReader constructor, works for UTF8 and other unicode marked files, but I'm looking for a way to detect code pages, like ibm850, windows1252.

Thanks for your answers, this is what I've done.

The files we receive are from end-users, they do not have a clue about codepages. The receivers are also end-users, by now this is what they know about codepages: Codepages exist, and are annoying.

Solution:

• Open the received file in Notepad, look at a garbled piece of text. If somebody is called François or something, with your human intelligence you can guess this.
• I've created a small app that the user can use to open the file with, and enter a text that user knows it will appear in the file, when the correct codepage is used.
• Loop through all codepages, and display the ones that give a solution with the user provided text.
• If more as one codepage pops up, ask the user to specify more text.

Android TextView Justify Text

How do you get the text of a TextView to be Justified (with text flush on the left- and right- hand sides)?

I found a possible solution here, but it does not work (even if you change vertical-center to center_vertical, etc).

Best way to convert text files between character sets?

What is the fastest, easiest tool or method to convert text files between character sets?

Specifically, I need to convert from UTF-8 to ISO-8859-15 and vice versa.

Everything goes: one-liners in your favorite scripting language, command-line tools or other utilities for OS, web sites, etc.

Best solutions so far:

On Linux/UNIX/OS X/cygwin:

• Gnu iconv suggested by Troels Arvin is best used as a filter. It seems to be universally available. Example:

  $ iconv -f UTF-8 -t ISO-8859-15 in.txt > out.txt

  As pointed out by Ben, there is an online converter using iconv.

• Gnu recode (manual) suggested by Cheekysoft will convert one or several files in-place. Example:

  $ recode UTF8..ISO-8859-15 in.txt
  This one uses shorter aliases:
  $ recode utf8..l9 in.txt

  Recode also supports surfaces which can be used to convert between different line ending types and encodings:

  Convert newlines from LF (Unix) to CR-LF (Dos):
  $ recode ../CR-LF in.txt
  

  Base64 encode file:
  $ recode ../Base64 in.txt     

  You can also combine them.

  Convert a Base64 encoded UTF8 file with Unix line endings to Base64 encoded Latin 1 file with Dos line endings:
  $ recode utf8/Base64..l1/CR-LF/Base64 file.txt

On Windows with Powershell (Jay Bazuzi):

• PS C:\> gc -en utf8 in.txt | Out-File -en ascii out.txt

  (No ISO-8859-15 support though; it says that supported charsets are unicode, utf7, utf8, utf32, ascii, bigendianunicode, default, and oem.)

Edit: Do you mean iso-8859-1 support? Using "String" does this e.g. for vice versa
gc -en string in.txt | Out-File -en utf8 out.txt Note: Th e possible enumeration values are "Unknown, String, Unicode, Byte, BigEndianUnicode, UTF8, UTF7, Ascii"

• CsCvt - Kalytta's Character Set Converter (http://www.cscvt.de) is another great command line based conversion tool for Windows.

PostgreSQL: Difference between text and varchar (character varying)

What's the difference between the text data type and the character varying (varchar) data types?

According to the documentation

If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.

and

In addition, PostgreSQL provides the text type, which stores strings of any length. Although the type text is not in the SQL standard, several other SQL database management systems have it as well.

So what's the difference?
