Unless you have quotas enabled, your user will be able to use as much space is available in /home, ie a bdf /home will show you what's available. Of course this space is shared with the other users who have home dirs under /home.
If quota is set on this user account "bts" then you can use just issue .. $ quota -v and it'll report the usage in this format .. Disk quotas for bts (uid ???): Filesystem usage quota limit timeleft files quota limit timeleft If quota is not set you can check what's the size of the filesystem "bts" is on by running.. $ cd $ bdf .
No .. du gives you the disk usage, not how much is allocated to "bts". The output means /u/bts_prod is currently using about 47MB of the disk space. Since you do not have disk quota set up your limit would be the FS limit. So just run .. $ bdf . in your home directory or run .. $ bdf /u/bts_prod from anywhere and look at the column "avail". That shows the amount of disk space (in KBytes) available to you and everyone else (if any) that are on this filesystem.
