Hello group,

In a bash script, what is the best way of calculating a directory path such /aDir/Backups/.

What I mean is I need to know finding out the available room under this directory.

Thanks,
ak

Hi


one way can be:

cd /aDir/Backups

df -h .

to see disk usage by directories in /aDir/Backups you can do

du -sh /aDir/Backups

thank you I have still a question. What you said works but why when I run:

$ df  

comparing to

$ df /usr/local

I get same number as available room? I thought that they should be different since every directory has assigned a percentage of the while size of hard drive.

Any comment?

Any comment?

1) df takes percentage(used memory)
EXAMPLE:

myfolder is in /var/myfolder and my partition /hda3 is mounted to /var
I get different results when I do df -h / and df -h /var

if you type just df -h you should see all partitons you have. In my case it is:
REAL EXMAPLE: :-)

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda2             897M  117M  733M  14% /
tmpfs                 253M     0  253M   0% /dev/shm
/dev/hda8              19G   49M   18G   1% /home
/dev/hda3              14G  175M   13G   2% /tmp
/dev/hda6             3.7G  360M  3.2G  11% /usr
/dev/hda7             1.8G   11M  1.7G   1% /usr/local
/dev/hda5              14G  535M   13G   4% /var
/dev/md0               74G  8.5G   62G  13% /srv

df -h /var/www/
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda5              14G  535M   13G   4% /var


2) why grade B if that worked?

So there is no way to get how much space is left under a specific directory such /usr/local ?

Sorry about B since I got the results but no details I found then. No worries next time I will make it up.
I'm a newbie so lot of question will be here.
