I’m looking for a way (using standard command) to find a file that is in
a directory up from the search location. The find command would
work fine, but I cannot find an option to get it to scan in the
upward direction in the directory tree. It only goes downward
in deeper level of directory.
Do you want to start it in the next directory up or do you really want to
find a file above you by any means necessary? “find / -name file” will start
the search for file in the root of the filesystem no matter where you are
but I’m sure that’s not what you mean.

I don’t know of a way to do it with a single command, but it’s pretty
easy with a shell script. Edit “/usr/bin/addvariant” and look for the
line “find the directory containing common.mk”.

Above the current level.

No that wouldn’t work cause it may find multiple instance of the file
I’m looking for. I’m very surprise “find” doesn’t have an option
to search backward.

That’s exaclty what I want to do. Problem is I want
to run this from a Makefile $(shell). I would really want to avoid the need
for an external script/program. As of now I’ve written a program
that does it but it has to be available in the user’s path.

Now I re-read this. Are you saying that you want to look in your parent’s
dir, then your parent’s parent’s dir, etc?
If so, write a program yourself. Readdir() isn’t that hard to use. I’ve
done this in QNX4. (I haven’t tried it in QNX6 yet.)

Using “;” to put multiple commands on one line, you should be able to hack
that together.

Exactly.

That’s what I done. There was not need for readdir since I know
the file I’m looking for, no need to scan the directory:
I’m basicly doing
stat( “file” );
stat ( “…/file” );
stat( “…/…/file” )
…
Until it success or it gives up after X level.

As I said in another post, I want to avoid using a program or a script.
I need to do this within a Makefile.

Mario,
Here’s a script:
#! /bin/sh
#__USAGE
#%C filename
file=$1
dir=$PWD
while true; do
[ -f “$dir/$file” ] && echo $dir/$file && exit 0
parent=dirname $dir
[ “$parent” eq “$dir” ] && break
dir=$parent
done
echo “File ‘$file’ not found”
exit 1
Of course you can strip this down considerably and use line-continuation
characters (’’) liberally in order to stuff it into a Makefile.

Preceed first line with ‘@’ and escape all newlines except last one with ‘’.
This is nice too. I had only used find -maxdepth 1 so that you could do
all the funky stuff that find lets you do…you know, mtime, type, etc.
If you’re just doing a simple search for a name, this is a much better
script.
