I don't know who needs to hear this but `man ascii` contains a complete table of all ASCII-7 values including their hex, decimal and octal equivalents
@mcc I refer to this man page frequently
@mcc this could have saved me so much time a few months ago!
@Gar *slamming fist on table sadly* once again i'm too late…
@Gar @mcc s/a few months ago/the past 25 years/;
@mcc this is going to help so much! every few hours working on a project I search for the ascii table online

@mcc there was a time in my life when typing "a" in the browser address bar would autosuggest asciitable.com - with its badly-compressed gif table, impossible to copy paste any of the entries, impossible to decipher the weird watermark in the background. If only I had been able to remember any other ascii table website domain, but then again I could have just memorized \n and \r in the first place.

Anyway, thanks for your PSA!

@mcc hUH?
@halcy I am not sure I understand what you are seeking clarification on
@mcc i’ve been looking up this table online for literal decades for no reason??
@halcy yes this was me as well until embarrassingly recently
@halcy @mcc Some of us just had an ASCII chart taped at eye level on the wall by the desk.
@mcc it me, unix user since ~1980. i needed to hear it.

That's a great Today I Learned!

Notepad++ has a useful side panel for this kind of thing in case that's also helpful.

@mcc I also don't know who needs to hear this
@mcc I approve this message!
@mcc the only tattoo I’ve seriously contested getting

@mcc I tend to use ascii(1) fron plan9(port) which defaults to hex and has -d, -o options, plus allows to encode/decode. (same kind of deal with the unicode command)

For example:

$ ascii -t 68 65 6c 6c 6f hello
@mcc Me, typing in `man unicode` immediately after this:
@mcc (unless, as I just discovered, you have the ascii utility installed, in which case you want man 7 ascii, which is oddly mnemonic)
@mcc you're mansplaining in the open 😱
@mcc @mulad omg that person is me
@mcc section 7 is a real gold mine
@mcc is this sort of advice considered "man-splaining"?
@mcc Finally no more Googling for an ASCII conversion table
@mcc For better or worse, `man unicode` is somewhat less comprehensive

@mcc I needed to hear this. For a while I had this in my reverse search:

python -c "print('\n'.join(f'{i:02x} {chr(i)}' for i in range(128)))"

@mcc also enormously useful, the ascii binary
@mcc this will be highly useful for me when I get stranded on Mars and need to communicate with Earth in hex ascii! 🙂
@mcc ascii-man, ascii-man, goes wherever a single byte can
@mcc I am such an old time Unix nerd that I knew that this page was in the Bell Labs 7th edition Unix from 1980 or so. Section 7, so you had to type "man 7 ascii" to get it.
@mcc Ah, one of the ancient and dusty scrolls.

Petition to alias mansplain=man
@mcc @jrose I discovered this just this week too! No idea why it took me so long to try it.
@mcc Everybody. That's who.
@mcc nobody wants to write the manpage for UTF-8? No? No takers? Darn 🥲
@corpsmoderne bizarrely it was Ken Thompson who invented the utf 8 binary encoding. If anyone was gonna be in a position to get a manpage added you'd think it would be him.
@mcc I was so expecting this to be a mansplaining joke that it took me several "but I don't get it" rereads, before I realised you meant an actual man page. That is useful, thanks!
@mcc Hello $10 DLE, my old friend. The first compression standard I learned about.
@cibyr Abolishing the State would fix this
@mcc I use this:

How to display ASCII characters from 0 to 127 in decimal, octal and hexadecimal format using linux bash script?

I have added the awk format to show the ascii character in bash script. But how can we actually display the ascii value in decimal, octal and hexadecimal in bash script? awk -F":" ' BEGIN { prin...

Stack Overflow
@mcc back when Google still had their "I'm feeling lucky" button, I would search "ascii table" and said button would bring me to exactly what I needed
@mcc Thanks for sharing, I still google that from time to time, which is ridiculous.
Do we have the same thing for UTF8?
@dolanor it would be nice. i have like, multiple websites i cross-reference together whenever i want to understand something about the unicode documents.
@mcc Obligatory nitpick; ASCII is 7-bits, so "ASCII-7" is redundant.
@balglaas I sometimes say this to be totally clear I mean the standard ASCII and not any of the nonstandard extensions.
@mcc It's too bad Mark Watney didn't know this
@mcc It's me, I needed to hear this. Thanks so much! 💜
