pipe every command

pipe every command

[shawn wilson]

is there a way to put every command through a pipe or redirect?

i'd prefer some way that i can put logic in so that i can exclude some
commands. but, basically i want everything to go through
'source-highlight' so:
ps ax | grep ssh
will end up:
ps ax | grep ssh | source-highlight -f esc256 -s shell

and:
sa
would end up:
sa | source-highlight -f esc256 -s shell

sa doesn't look as nice as ps with this option, but hopefully i'll be
able to determine what command was given and have some logic to give
different options or none at all (for interactive commands like vim or
tmux, this might not be so good - it fails hard with vim anyway).

There might be a way to do this in the way you're talking about, but I 
accomplish a similar goal (being able to easily pipe things through 
`less`) using global aliases:

alias -g L='| less'

You could use:

# H = highlight
alias -g H='| source-highlight -f esc256 -s shell'

Then to use it, the following examples would expand into your example 
commands:

ps ax | grep ssh H

or:

sa H

Not very surprising -- Tmux and Vim require pretty full control of 
terminal I/O, so piping either one through a command won't do anything 
useful.

not as nicely baked in as i was hoping, but i guess it'll work. thanks
