Using svn command line option
Use the following diff command to avoid diff context
$ svn diff --diff-cmd=diff -x -U0
Option -x
passes option -U0
to the diff command which make 0 line context.
Using alias
Set the following svndiff alias in ~/.bash_profile
alias svndiff='svn diff --diff-cmd=diff -x -U0 -x -w'
Now source the ~/.bash_profile. It is not needed when we login again.
$ source ~/.bash_profile
After that we can simply use svndiff
$ svndiff
