another solution :
 echo "/u01/Sybase/data/master.dbf" |sed 's:.*/::g'

in that command : sed 's:<old value>:<new value>:g' substitute the old value with the new value

. means any character or number
* matches the previous character set zero or more times
the new value is null
g means global replacement, replace the old value by the new one everytime u see it
Thus, the whole expression is translated to : substitute anything followed by a slash with "nothing"
So it deletes the path and u'll get the basename.

Hope that helps.
