How To Clear btmp File

By admin on April 21, 2015 in Linux

Running low on storage. Check the /etc/btmp file where failed login attempts are logged. This file may be very large:

ls /var/log/btmp

1	ls /var/log/btmp

The file can be cleared like this:

cat /dev/null > /var/log/btmp

1	cat /dev/null > /var/log/btmp
