crow is a simple tool for Linux that effectively duplicates the functionality of xargs, but with a peculiar bit of syntax and more appropriate defaults for casual use.
Any expression enclosed in -[ brackets like these ]- will be evaluated, and each line of its output will be expanded as one argument. crow's command line arguments can be used at the beginning of any such expression. These expression brackets may be nested and they may be used in initial position to generate command names (but be careful with this.)
By default, crow expects the first term it sees to be the name of an executable, and treats the rest as its arguments. This means that it will ignore aliases and shell commands; use the -c argument to pass it to the shell.
