Is there a unix program to display ASCII ? Hex ?

[mikey777]

Sometimes I need a program to just display ASCII codes, rather than look it up. I wrote a program in C to do this on Win/XP using Watcom. Is there a unix program that does this ?

Also, it there a program like Frhed to display a file in hex for unix ?

To view files in different format man od

Or hexdump(1).

man ascii will show the ASCII table.

For a hexdump of a file:

hexdump -C filename

Years ago I wrote a small utility that displays the ASCII code of keys pressed as decimal, hexadecimal, octal. binary and symbolic names. I still use it occasionally.

od -t x1

editors/hexedit is a very basic hex editor for the console. It shows ASCII, hex, and lets you edit stuff.
There is also a graphical hex editor, editors/whexeditor.

There is also a program called xxd which can take a hex dump and change it to binary. It is sometimes usefull in shell script tha need to manipulate binary files.

Yes, that's only installed by editors/vim and editors/vim-console though. Nothing else will install it, including editors/neovim and editors/vim-tiny.
