Using the ever useful grep, with -l option, it outputs only the matching filenames:

grep -rl --exclude '*.svn*' CMFCore *

vim loads multiples file in one line separated by spaces. So I need to join the multiple lines into one, separated by space. Here we have the paste command. For each line, put a space as the separator:

paste  -s -d " "

Finally I wanted vim to load this in GUI mode with tabs, so we put it together:

gvim -p $(grep -rl --exclude '*.svn*' CMFCore *  | paste  -s -d " " -)

• the part inside the $( ) is the output of the command.
• using pipes | the output of grep (the list of files) is read by paste
• the - in paste is telling it to input the stdout output of grep

I then quickly have my editor setup for work,
