Hi,

I like to copy a bunch of directories from one tree to a new location,
I am using 2 find commands:

find . -type d -name run -maxdepth 4 -exec mkdir -p /tmp/{} \;
find . -type d -name run -maxdepth 4 -exec cp {}/the_file /tmp/{} \;

Is there a way I can put the 2 commands together after -exec in one
find command? I tried the following, but got syntax error:

find . -type d -name run -maxdepth 4 -exec mkdir -p /tmp/{} && cp
{}/the_file /tmp/{} \;

and

find . -type d -name run -maxdepth 4 -exec { mkdir -p /tmp/{} &&
cp {}/the_file /tmp/{} } \;


Thanks.

Note that the syntax above is not standard as {} is not an
argument by its own. But find implementations that support the
non-standard -maxdepth also support that.


find . -type d -name run -maxdepth 4 -exec mkdir -p /tmp/{} \; \
-exec cp {}/the_file /tmp/{} \;


Or portably:

find . -type d -name run -maxdepth 4 -exec sh -c '
mkdir -p "/tmp/$1" && cp "$1/the_file" "/tmp/$1"' sh {} \;

[...]

&& is a shell operator that delimits commands, so above you'd
run the find command and then the cp command if find was
successful.

Isn't there a way with tar and a pipe?

Here's something from my personal notes:


tar: trick: To COPY Dir-TREE: "cd fromdir ; tar cf - . | (cd todir && tar xfBp -)".
tar: trick: To COPY Dir-TREE: "cd <FROMDIR> ; tar cf - . | (cd <TODIR> && tar xfBp -)".
tar: ===>> (ALSO, see pg 216 of UNIX USER TOOLS, 2nd ed) <<<============ !!!!!


Which reminds me -- BUY THAT BOOK, "unix power tools" 3d ed, O'Reilly.

Consists of 1000 or so pages of hints and tricks all lifted from
these usenix groups.

Trust me, guys. Get it.
Cheap from nerdbooks (is where you go now if you used
to go to the "late" bookpool)
