$ ulimit -aExample of output: The above output clearly stat that you can create file size upto 805MB limit.
To change this limit or if you do not wish to have a limit you can edit your /etc/security/limits.conf file (login as the root):
Look for your username and fsize parameter.
Delete this line or set new parameter.
For example consider following entry where I am setting new file size limit to 1 GB:
If you wish to setup limit for all users, use * on place of username like this (5GB limit):
If you don't want to apply any limits, just delete or comment entry for your username from this file.
Save the changes. Log out and log back in for the changes to take effect.
Now your limit is 1GB file size. If you do not want any limit remove fsize from /etc/security/limits.conf.
