feature-request: brief syntax for $(type -p somecommand)
It would be nice if there was some really brief syntax for $(type -p somecommand)
Re: feature-request: brief syntax for $(type -p somecommand)
[Oops--I sent that incomplete.] It would be nice if there was some really brief syntax for $(type -p somecommand) I find myself using this all day long with 'ls', 'file', 'ldd', 'strings', 'nm', etc., and the current incantation is just long enough to be annoying. Mike

Use a function, e.g.:
p()
{
pp=$( type -p $@ )
}

Hmm. So I would use this like so?
$ p somecommand; ls -l $pp
I guess it's not obvious that that's an improvement. Along these
lines, though, is there some way to do something like this
script named 'p':
$!/bin/bash
exec type -p $1
which could then be used like
$ ls -l $(p somecommand)
except without the external script?

If that's what you want, you can include it in the function:
p()
{
_p=$( type -p $@ )
[ -n $_p ] ls -l $_p
}

Mike Why do you need to get the path of a program that's in PATH? If you only need to check if it's in PATH then you can use other things, and these in a loop. J.

Mike Why do you need to get the path of a program that's in PATH? Well, for example, I may have an undocumented program 'foobar' in my path, and running 'strings' on it is a good way to grab its usage message and/or look at its embedded messages, etc. I might run 'ldd' on it to see what libs it's depending on, 'ls' to see when it was last updated, who owns it, etc., 'file' to see what it is (script or executable, 32-bit or 64, etc.). Obviously for all of these, I could do a 'type -p' first and then paste the result in as the argument for these other commands, but it's handy not to have to do that. Currently I have a whole bunch of aliases (pls, pfile, pldd, pstrings, etc.) to do this, but it seems like a useful enough pattern that it'd be worth having a general shortcut for it. Mike

This is more or less what I'm doing now, with one function for each
command. I suppose the command could be an argument, too, so that one
could run
$ p ls somecommand
$ p ldd somecommand
$ p strings somecommand
$ p file somecommand
$ p nm somecommand
though there's no command completion this way. I guess I could add that, too.
One problem, though, like the wait for slot feature I suggested a
few months ago, is that something like this is quite a bit more useful
when it's available everywhere (without having to drag one's bash
library around).

I have a more universal function (also named p) here:

Maybe it is of use for you, too.
