delay: a simple scheduler
the "delay" utility is an invaluable tool for me. with gnu-screen it allows you to schedule something and have it run and output to the current terminal, unlike "at". You can also use it like "sleep" with seconds and also with date: delay until 13:33 friday && echo test get it from: http://onegeek.org/~tom/software/delay/current/delay.c (author: Tom Rothamel)

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.

[vim] Clear trailing whitespace in file
% acts on every line in the file. \s matches spaces. \+ matches one or more occurrences of what's right behind it. Character '$' matches end-of-line.
