Which unnecessary files can i delete in the root folder?

epamuk · 08-10-2009, 08:37 AM

Hi,

I have used Redhat Red Enterprise Linux AS release 4 Update 6. I have a free size problem on the root folder. Root folder Using %92 space. Therefore It have 800 mb free size.

I want to delete unnecessary files in the root folder. Which files can I delete in the root folder?

Example, windows have temp folder. And Windows system admins can delete temp folder files for open free size. Does linux system have any folder as temp?

Which files i must delete in the folder for open free size?

Thanks.

You can use the command du to find where a lot of space is used. Next you can analyze that.

And yes, there is a /tmp directory. The other directory that you might want to look at is /var as it contains a lot of logfiles.

Please use du command as shown below.

Code:

[root@localhost ~]# du -h --max-depth=1 /
16K     /lost+found
du: cannot access `/proc/20610/task/20610/fd/4': No such file or directory
du: cannot access `/proc/20610/task/20610/fdinfo/4': No such file or directory
du: cannot access `/proc/20610/fd/4': No such file or directory
du: cannot access `/proc/20610/fdinfo/4': No such file or directory

4.0K    /srv
2.3G    /usr
76M     /var
2.7G    /
[root@localhost ~]#

It will show you the 'real size' of directories. When posting, please use code tags (as I did) as it retains the formatting.

Note: taken on an acer aspire one, so the numbers might not be a reference.

Hi Wim,

I worked your write command and I saw /usr/lib and /usr/share have a lot big size. This folders contain a lot files. And Maybe I can delete some files in the this folders. Which files can i delete from this folders?

Thanks.

I'd e looking in /usr/share from that output, but you wouldn't ever just delete files, you'd remove the packages that are responsible for those files being there.

Same issue here, but I also have files in /usr/share that are come from other systems (I was going to share /usr/share to independent partition with other systems but looks unwell), then you’re nowhere to remove them using packages removal.

OK. No question here, nor any information. How does your problem relate to this 9-year-old thread?

Please start a new thread with the details of the problem you want help with. Thank you.
