Console File Viewer which shows byte position numbers

I have a large data-file with record length 800 bytes. It is to big to open it in gui-texteditors, but less and grep is working fine.

But I need to see fast which number is in the records on position 61 and 451 and so on. Is there a file-viewer or maybe function in less to display the byte numeration within a record?

on mainframe we have something like that:

Is there something like that in Linux?

I'm not sure what your "mainframe" example is supposed to show - can you add a small, testable example of the real input and desired output?

And are you sure GUI editors can't open it? I often use emacs on files that are several gigabytes in size. Finally, are you just looking for something like `head -c 143 | tail -c1` to see what character is at the 143th byte of the file?

This example is showing a line of a data file. first row is the character-line, second and third line is the hex-value of this byte and line four is the byte position number to see on which position this byte is located within the record. at the moment i am working with head and tail like terdon said. but nicer would be to have such a tool to display one line of file.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
