Open in TextMate Sidebar files (recursively) with names matching REGEX_A and not matching REGEX_B
This does the following: 1 - Search recursively for files whose names match REGEX_A 2 - From this list exclude files whose names match REGEX_B 3 - Open this as a group in textmate (in the sidebar) And now you can use Command+Shift+F to use textmate own find and replace on this particular group of files. For advanced regex in the first expression you can use -regextype posix-egrep like this: mate - `find * -type f -regextype posix-egrep -regex 'REGEX_A' | grep -v -E 'REGEX_B'` Warning: this is not ment to open files or folders with space os special characters in the filename. If anyone knows a solution to that, tell me so I can fix the line.
