'pee "command1" "command2"' outputs everything from command1, then
everything from command2. Example:
% seq 3 | pee "cat" "tac"
1
2
3
3
2
1
There's no switch (I'll call it '-r') to output line #1 from command1
and line #1 from command2, then line #2 from command1 and line #2 from
command #2, etc. Example:
% seq 3 | pee -r "cat" "tac"
1
3
2
2
3
1
One of many uses: 'head' & 'tail' could be used to sample or compare the
outputs of similar programs, or different versions of the same program.
Variant: an '-rl' switch to output all line #Ns on the same line, maybe
with an optional delimiter string to separate them. Example:
# " : " is the separator.
% seq 3 | pee -rl " : " "cat" "tac"
1 : 3
2 : 2
3 : 1
Such output would be easy to parse with 'set', 'sed', 'cut', 'printf',
etc. Uses: culling data from similar utils (or mutually exclusive
switches of a complex util) when you want part of the output of util
#1, and part of the output of util #2, etc.
(Note: the '-rl' switch letters are arbitrary, call 'em anything.)
