The unix tee
command splits the standard input to stdout AND a file.
What I need is something that works the other way around, merging several inputs to one output - I need to concatenate the stdout of two (or more) commands.
Not sure what the semantics of this app should be - let's suppose each argument is a complete command.
Example:
> eet "echo 1" "echo 2" > file.txt
should generate a file that has contents
1
2
I tried
> echo 1 && echo 2 > zz.txt
It doesn't work.
Side note: I know I could just append the outputs of each command to the file, but I want to do this in one go (actually, I want to pipe the merged outputs to another program).
Also, I could roll my own, but I'm lazy whenever I can afford it :-)
Oh yeah, and it would be nice if it worked in Windows (although I guess any bash/linux-flavored solution works, via UnxUtils/msys/etc)
