UNIX for Dummies Questions & Answers

Hi,
How can I check whether a directory has enough space to create file? I have checked the space is availabe in the file system.
For example: the directory /var/tmp resides in root file system. In the root file system currently 20% (5.5gb) space availabe. but how can I check the in the /var/tmp, I can create a file which will have size nearly 1gb.

Thanks & Regards,
Siba

You say that your /var/tmp is a sub directory in the filesystem /. You say you have 5,5 GB of free space in it. Now you ask hoe you can check if it can hold a file of 1 GB...
I don't understand what the problem is since you already answered your own question.
A filesystems space you can check with

Code:

df -k

which you already did, I guess. Else you might not know you got 5,5 GB of free space there. Any subdirectory of that filesystem's mount point share that space.
If you are unsure, cd to /var/tmp and do "df -k ." and see if it has at least 1 GB free space for your needs.

Maybe I just did not understand what you want
