Set max. character limit with echo

[pseudo knot]

rad

[harsh granite]

what no

[slate birch]

@harsh granite d Can you explain what the objective is?

[harsh granite]

ok, so basically: I have echo "$B - $A" and if $A is longer, than... let's say 35 characters, only use the 35 characters of that and end it with ...

[slate birch]

${variable:0:35}

[harsh granite]

Is there a way to end it with ...?

[slate birch]

Just use a branch

string="$A - $B"

if [[ ${#string} -gt 35 ]]; then
  echo ${string:0:35}...
else
  echo "$string"
fi

[slate birch]

Or use sed

sed 's/\(^.\{35\}\).*/\1.../'

[harsh granite]

unreadable, but exactly what i was looking for. thanks!

[neon crag]

Unreadable?

[slate birch]

No offence, just a test

[neon crag]

Is it a pangram though?

It isn't...

[slate birch]

I recommend reading the bash man page from line 1207 onwards.

[slate birch]

sudo sometimes French taunts you if you mistype your password.

[neon crag]

What do you mean here?

"Sudo sometimes taunts you in French if you mistype your password?"

That's the next closest semantically correct sentence I see... @slate birch

[slate birch]

No, it does French taunts you

Search "French taunt"

[neon crag]

So what's with the "sudo" particle at the beginning?

[slate birch]

I don't know if there is a sudo particle besides fermions, quarks, leptons, bosons, photons, protons, gravitons, glutons, neutrons and electrons.

[neon crag]

What is that "sudo" at the beginning, it's unreadable.

Well, maybe you just didn't put in effort to writing your sentence there, so I won't bother.

[slate birch]

Well, maybe you just didn't put in effort to reading my sentence there, so I won't bother.

[neon crag]

Yes, it must have been a sentence with effort put into it, as it doesn't even capitalize the first letter.

[slate birch]

comity of courtesy is congruent, consequently, cease
your conterfeit condemnation.

[neon crag]

This yes, it's from the movie, which many don't know.

[neon crag]

Though this, I don't understand the reference.

[slate birch]

of course not, You are english-types

[neon crag]

Ah, and you know this reference...

Of course you do...

[slate birch]

What a strange person.

[neon crag]

You know that communication is not done like that.

Just like a person who knows of Linux very well, and is talking about bootloaders to a windows user, who doesn't.

[slate birch]

i don't want to talk to you no more, i fart in your general direction. Now go away, or I shall taunt you a second time.

[neon crag]

Literally you.

Except the girl part. And Linux substituted with some old movie refrences.

[slate birch]

You are in the wrong thread.
