Execute + time a program. Echo the command line and execute a command while redirecting IO, making pipes, and/or printing timing information at the end of the program. Next to some global IO redirections (these act on the complete pipe, and are not echoed back), specific IO redirections can be specified as well. The following constructions are supported:

[12]>

redirect stdout/stderr to a certain file (next argument)

[12]>>

redirect + append

0<

redirect stdin to a certain file (next argument)

1>&2

set stdout to stderr

2>&1

set stderr to stdout

Parsing if IO redirection is left-to-right. See the 'bash' manual for more details.
