cp not working

Fixit7 · 03-04-2014, 09:23 PM

This works fine up to the cp lines.

I can not understand why is says no file/directory when there are both ?

Thanks.

I have even read bash tutorials and made a number of posts.

cd /
cd root
cd Icons
zip Linux_Icons *.png
cp Linux_Icons /mnt/sdb1/STORAGE
cp Linux_Icons Storage

Quote from the zip manpage:

"If the name of the zip archive does not contain an extension, the extension .zip is added. If the name already contains an extension other than .zip the existing extension is kept unchanged."

In your case, the name of your ZIPfile will be "Linux_Icons.zip".

png images are already ziped

they use libz to compress

it would be better to just tar up the folder

I would like to see if a zip file takes up any less space than just the .png files.

Is there a way to modify this so it shows the total amount of bytes ?

Code:

du -sh -b *.png

if you try to zip a png it likely will be about 0.5% to 1% bigger

Use ls -l to see size.

I meant the total number of bytes of ALL files added up together.

Like Windows dir *.png would give.

just zip a single png image and compare it

Code:

ls -l 
-rw-r--r-- 1 ?????? ????? 751779 Feb 19 00:41 1.test.png
-rw-r--r-- 1 ?????? ????? 752064 Mar  9 19:50 1.test.png.zip

I know I can do that.

Does that mean that Linux has no way of giving a total number of bytes for a set of files ?

This is something that I would use often.

Try du -c *.png to get the total (add -h, -b, etc for the number format you want).

Fixit7 · 03-23-2014, 08:40 PM

Thanks.

Using in /bin

du -a -c -h -b *.* > dir.txt

I got this, but it should be a much larger list.
