README
README for Android "acp" Command The "cp" command was judged and found wanting. The issues are: Mac OS X: - Uses the BSD cp, not the fancy GNU cp. It lacks the "-u" flag, which only copies files if they are newer than the destination. This can slow the build when copying lots of content. - Doesn't take the "-d" flag, which causes symlinks to be copied as links. This is the default behavior, so it's not all bad, but it complains if you supply "-d". MinGW/Cygwin: - Gets really weird when copying a file called "foo.exe", failing with "cp: skipping file 'foo.exe', as it was replaced while being copied". This only seems to happen when the source file is on an NFS/Samba volume. "cp" works okay copying from local disk. Linux: - On some systems it's possible to have microsecond-accurate timestamps on an NFS volume, and non-microsecond timestamps on a local volume. If you copy from NFS to local disk, your NFS files will always be newer, because the local disk time stamp is truncated rather than rounded up. This foils the "-u" flag if you also supply the "-p" flag to preserve timestamps. - The Darwin linker insists that ranlib be current. If you copy the library, the time stamp no longer matches. Preserving the time stamp is essential, so simply turning the "-p" flag off doesn't work. Futzing around these in make with GNU make functions is awkward at best. It's easier and more reliable to write a cp command that works properly. The "acp" command takes most of the standard flags, following the GNU conventions. It adds a "-e" flag, used when copying executables around. On most systems it is ignored, but on MinGW/Cygwin it allows "cp foo bar" to work when what is actually meant is "cp foo.exe bar.exe". Unlike the default Cygwin cp, "acp foo bar" will not find foo.exe unless you add the "-e" flag, avoiding potential ambiguity.
