The d command
Run make or other commands in the background, with output to a file.

If you use the command line very much at all...

Usage: d [ -f file ] c[a][n][r][x][p][f|w|!] cmd [ arg ... ]
or:    d [ -f file ] m[a][n][r][x][p][f|w|!] [ make-arg ... ]
or:    d [ -f file ] s[a][n][r][x][p][f|w|!] [ additional-arg ... ]
or:    d [ -f file ] h

Run a command in the background, with its stdout and stderr redirected to a log file called 'out' or to the given file. The -f file option changes the name of the log file persistently.

The d command does
   mv out ,out
before creating a new 'out' file unless told to append instead.

The first argument to the d command, the todo argument, must consist of one of these:
c Run the following command. You can use ;|> etc. if you escape them
m Run 'make' with the arguments given.
s Run the same command again. Extracts the last command from 'out' and runs it again, as root if the previous run was as root, and without 'nice' unless you ask for 'nice' again.
h Print a history of commands logged in 'out'.
You can add any of these:
a Append to 'out'.
n Do it 'nice'ly.
r Do it as root.
x Clear the screen.
, First,  mv ,out out
! Disown the process, so it will continue if you log out. Put this last so your shell won't interpret it as asking for shell history.
and one of these:
p Just print the command that would be executed; don't run it.
w Wait for it.
f Wait for it, and show the command output as it progresses.

The d command comes along with several helper shell functions:

q tail -f out
qq cat out
qt tail -20 out
cq clear ; q
cqq clear ; qq
wq wait "$@" ; printf "\007" ; qq
wqt wait "$@" ; printf "\007" ; qt

The output from d into the file 'out' consists of
   prologue
   output from the command
   epilogue
as shown in the example below, which does this:

223 Z% d c 'sleep 5 ; echo Hello Folks'
[5] 3937
224 Z% 
[5]  + 3937 done       yostD_run
224 Z% d sna
Run again nice: sleep 5 ; echo Hello Folks!
[5] 3965
225 Z% 
[5]  + 3965 done       yostD_run
225 Z% qq

Download d.sh.

To use the d command and its helpers, you need to source d.sh from your zsh or bash.

I have tested this only with zsh 5.0.5 and bash 3.2.51(1)-release. Please feel free to send bug fixes.
