Re: [Solved] Convert a binary file to unicode file

Your source file must be in a language.

Can use iconv.

Re: [Solved] Convert a binary file to unicode file

I tried with iconv -f binary -t uff-8 worldcitiespop.txt > output.txt but it says

iconv: le conversioni da "binary" e verso "uff-8" non sono supportate

that means that the conversion is not supported.

Run

LC_ALL=C <command>

to get output in English.
If you enabled C locale, it should work.


How did you get this file, why such conversion is necessary?

Re: [Solved] Convert a binary file to unicode file

The file is located here.

I neet to convert it to manage it with Java and create a SQL query for my table.

Do copy and paste with KWrite works, but I can't do it because that file has huge number of line and my PC is not good enough to manage it. Would you please do that for me and post the result? sad

Re: [Solved] Convert a binary file to unicode file

Hi,

that file is compressed (with gzip). Twice. Compressing a file twice usually is a mistake.

$ file worldcitiespop.txt.gz
worldcitiespop.txt.gz: gzip compressed data, from Unix
$ zcat worldcitiespop.txt.gz > worldcitiespop.txt
$ file worldcitiespop.txt
worldcitiespop.txt: gzip compressed data, was "worldcitiespop.txt", from Unix, last modified: Wed Apr 27 22:54:01 2011
$ zcat worldcitiespop.txt > worldcitiespop2.txt
$ file worldcitiespop2.txt 
worldcitiespop2.txt: ISO-8859 text

This has nothing to do with encodings like unicode, you simply have to uncompress it (twice).

You can try 'split' to cut the big file into manageable pieces.

[karol@black test]$ wc -l < worldcitiespop.txt 
2797246

Don't tell it to me. The text file is in the archive.

Errr ... this command tells you how many lines there are in the file.

You need to use zcat twice, like Vain wrote.

[karol@black test]$ zcat worldcitiespop.txt.gz > worldcitiespop.txt
[karol@black test]$ zcat worldcitiespop.txt > foo.txt
[karol@black test]$ file foo.txt
foo.txt: ISO-8859 text

Re: [Solved] Convert a binary file to unicode file

Thank you very much smile It worked, except for the char encoding that is ISO-8859 sad

Re: [Solved] Convert a binary file to unicode file

Please read the man page:

[karol@black test]$ iconv -f ISO-8859-1 -t UTF-8 foo2.txt > foo3.txt
[karol@black test]$ file foo3.txt 
foo3.txt: UTF-8 Unicode text
