Bash: Copy named files recursively, preserving folder structure

Question

I was hoping:

cp -R src/prog.js images/icon.jpg /tmp/package

would yield a symmetrical structure in the destination dir:

/t         


        

Answer 1

rsync of course! tutorial here. and here

Or unison

Answer 2

Try...

for f in src/*.js; do cp $f /tmp/package/$f; done

so for what you were doing originally...

for f in `echo "src/prog.js images/icon.jpg"`; do cp $f /tmp/package/$f; done

or

v="src/prog.js images/icon.jpg"; for f in $v; do cp $f /tmp/package/$f; done

Answer 3

rsync's -R option will do what you expect. It's a very feature-rich file copier. For example:

$ rsync -Rv src/prog.js images/icon.jpg /tmp/package/
images/
images/icon.jpg
src/
src/prog.js

sent 197 bytes  received 76 bytes  546.00 bytes/sec
total size is 0  speedup is 0.00

Sample results:

$ find /tmp/package
/tmp/package
/tmp/package/images
/tmp/package/images/icon.jpg
/tmp/package/src
/tmp/package/src/prog.js

Answer 4

Alternatively, if you're old-school, use cpio:

cd /source;
find . -print | cpio -pvdmB /target

Clearly, you can filter the file list to your heart's content.

The '-p' option is for 'pass-through' mode (as against '-i' for input or '-o' for output). The '-v' is verbose (list the files as they're processed). The '-m' preserves modification times. The '-B' means use 'big blocks' (where big blocks are 5120 bytes instead of 512 bytes); it is possible it has no effect these days.

Answer 5

One way:

tar cf - <files> | (cd /dest; tar xf -)

Answer 6

Have you tried using the --parents option? I don't know if OS X supports that, but that works on Linux.

cp --parents src/prog.js images/icon.jpg /tmp/package

If that doesn't work on OS X, try

rsync -R src/prog.js images/icon.jpg /tmp/package

as aif suggested.
