What is total in "ls -l" command ?

[sunbiz_3000]

Can anyone tell me what the total <?????> refer to when we give the ls command with the -l arguement ????

My teacher told me its the no. of bytes, but that doesnt seem to be true in my PC...

[markwolfe Veteran]

Size in bytes.

Do an ls -lh to put it in "human readable" units. ;)

[EDIT: Yes, your teacher is correct. ;) ]

Looks more like kilobytes to me.

[nuka_t]

nope, ls- lh is megabytes, it even says xxM

[Tek]

No one's talking about ls -lh, look at the top of the output of ls -l at 'total'.

[nuka_t]

the post right above yours was talking about ls -lh.

however, i just checked and ls -l is in kilobytes, not bytes. also, ls -l gives me 12,345 and ls -lh gives 11M

why does it round wrong like that?

You've got a file that's 12345kb? Sounds like you made that one up :whistle:

I have several html files a few kb in size, and here is my output of ls -l

[mark@localhost 192.168.1.2]$ ls -l
total 92

At least on my Fedora box, it is in bytes.

ls -l = kilobytes for me

ls -lh = megabytes

Do you have an alias set up?

ls -lh should switch between bytes, KB, and MB based on filesize... :unsure:

It does. I needed to check a few other folders.

But... ls -l always shows KB for me.

Why'd you complain about it rounding to 11 then?

I get bytes as well. Which makes more sense than kb, since not every file is in the kb range, but should be at least 1 byte.

i just made up a nubmer. what it really was was something like

73,333 rounding down to 72. ill try to post a screenie.

Actually it would be rounding up in that case. Since 73333MB/1024(MB/GB)=71.6GB

If you use --si, then it'll use 1000 instead of 1024.

[nuka_t]

aaah, gotcha. thats what i thought it was, at first, but i wasnt sure.

Isn't switching between powers of 10 and 2 wonderful? :laugh:

This is why hard drive manufacturers suck, they stick to powers of 10 instead of powers of 2 like they should be :rolleyes:

I know... They even added an --si option to the ls command to put it in "Drive Manufacturer Units" :rofl:

In the CODE that you have given, I was asking what that total<92>, 92 was. I dont think that is in bytes.

I know that the fifth column which has <5638>, <2997> those are in bytes, but I wanted to know what is that 92 ???

All of the numbers that I have posted have been about the total at the top not the fifth column. I don't think that some of the others understood your question.

In his example 92 stands for 92 kilobytes not bytes.

Oops! :blush:

You are exactly right, Fred. I was going off the individual file sizes. I guess a picture was literally worth 1000 words, as the output of the ls query helped make things clear what the original poster wanted.

Oops for me too! :blush:

Although we had a few people asking questions on different parts of the output of ls.
