If you want to send somebody parts of your svn repository, then you mostly do not want to give them your .svn folders with all the settings and base files inside.
I wrote a short command to remove all the .svn folders recursive from the current directory:
for dir in $(find . -name ".svn" -type d); do rm -rf "$dir"; done
find . -name ".svn" -type d
- Will list recursive all directorys named '.svn' in current directory.
for dir in $(...); do rm -rf "$dir"; done
- Will delete all items from the result of $().
If you do not want to type and remember that much, you can easily add this as a bash alias.
Open your .bashrc and add this line:
alias unsvn='for dir in $(find . -name ".svn" -type d); do rm -rf "$dir"; done'
The next time you start a bash, you have a new command "unsvn".
