yesterday i was shown that i can't unmount a mounted partition (like /media/test or /mnt/test) if someone is using the terminal in that directory (maybe in ssh connection).
he used a command that listed the user on that directory with pid of process in order to kill the pid and unmount the partitions.
I don't remember the command, could you help me?
ty
This one works nice:
lsof | grep '^bash.*cwd'

What command line would give me a list of programs each logged in user is executing for a Linux server using bash?
You can use the w command for this.
As #ivanivan mentioned, a more complete listing can be accomplished using ps, usually coupled with grep to filter out what you don't want.

How I can find out how much /tmp space is required by an application. Generally sometime I see /tmp is full and get error saying not able to write to /tmp. So is there any way to find out how much /tmp space is required by an application ?
There is no way. Programs use /tmp on an ad-hoc basis.

How can I block someone from spamming by console using the "write" command in unix.
Run the command mesg n. Preferably, add it to your .bashrc or equivalent so it runs when you start up.
In your console, type:
mesg n
For more information, read the manual pages (man mesg).
