Как просмотреть содержимое файла .dat в linux

У меня есть файл с расширением .dat, как я могу просмотреть содержимое файла в гекса? Я имею в виду, что если я открою файл, я смогу увидеть содержимое в шестнадцатеричном формате, это можно сделать с помощью редактора vim. Я установил tnef, но когда я пытаюсь открыть этот файл, он говорит: «Кажется, что это не файл TNEF»

Во-первых, файл dat может быть чем угодно. Используйте file .dat чтобы найти его. Затем, в зависимости от его типа, используйте конкретное приложение, чтобы открыть его.

file — хорошая команда, чтобы попробовать сначала.

После этого я использую cat -v | less или od -a | less для «читабельного» представления. Проверьте man страницы для od и file .

xxd более современен, чем od , и часто генерирует более красивое представление, но иногда доступен только od .

Конечно, у mc (во многих серьезных дистрибутивах, доступных с базового установочного CD) есть HEX viewer. Доступ к режиму просмотра идентификатора можно получить с помощью F4.

это можно сделать с помощью редактора vim [?].

Итак, как обычно, откройте файл в vi, нажмите escape и введите :%!xxd для перехода в шестнадцатеричный режим

И когда вы закончите, нажмите [escape] еще раз и наберите :%!xxd -r для выхода из шестнадцатеричного режима.

Хорошо, так что это не то, чтобы на самом деле переключаться в «шестнадцатеричный режим» vi; Ви не имеет. То, что на самом деле делает выше, — это поток буфера vi через внешнюю программу ‘xxd’.

Попробуйте добавить следующее в /etc/vim/vimrc.local , и вы получите сочетания клавиш для переключения вперед и назад (F8 и F7).

" Switch to hex-editor` noremap :%!xxd " Switch back noremap :%!xxd -r

How to view the contents of .dat file in linux

I have a file with .dat extension how can i view the contents of the file in hexa ? mean if i open the file i should be able to see the contents in hex format, can this be done using vim editor. I have installed tnef but when i try opening this dat file it says «Seems not to be a TNEF file»

That depends on what the file is. .dat is such a generic extension that it could be anything. Where did you get the file from? What type of data do you expect to be contained in the file?

Firstly, the dat file can be anything.

Use file .dat to find what it is. Then depending out its type, use specific application to open it.

Some common Linux utilities for viewing hex dumps are:

file is a good command to try first.

After that, I use cat -v | less or od -a | less for a «readable» view. Check the man pages for od and file .

xxd is more modern than od , and often generates a prettier view, but sometimes only od is available.

Of course mc (in many serious distros available from basic install CD) has HEX viewer. It can be accessed id view mode by F4

can this be done using vim editor[?].

So, open a file in vi as usual, hit escape and type: :%!xxd to switch into hex mode

And when your [sic] done hit escape again and type: :%!xxd -r to exit from hex mode.

Okay, so this isn’t actaully switching to vi’s ‘hex mode’; vi doesn’t have one. What the above actually does is to stream vi’s buffer through the external program ‘xxd’.

Try adding the following to /etc/vim/vimrc.local , and you’ll get keyboard shortcuts for switching back and forth (F8 and F7).

" Switch to hex-editor` noremap :%!xxd " Switch back noremap :%!xxd -r

There is also a Vim tip on this subject.
