\fBgcp\fP is a file copier, loosely inspired by cp, but with high level functionalities like: |
|
|
|
\- transfer progression indication |
|
|
|
\- continuous copying when there is an issue: it skips the problematic file and goes on |
|
|
|
\- copy status logging: which files were effectively copied |
|
|
|
\- name mangling to handle target filesystem limitations (e.g. removing incompatible chars like "?" or "*" on vfat) |
|
|
|
\- forced copy serialization: new files to copy are added to a global queue to avoid hard drive head seeks |
|
|
|
\- transfer list management: gcp can save a list of files to copy and reuse it later |
|
|
|
\- approximate option compatibility with cp (approximate because the behaviour is not exactly the same, see below) |

.SH OPTIONS |
|
|
|
These programs follow the usual GNU command line syntax, with long |
|
|
|
options starting with two dashes (`-'). |
|
|
|
By default, calling gcp is equivalent to calling gcp \-\-preserve=mode,ownership,timestamps. |

.SH LIMITATIONS |
|
|
|
Timestamps preservation with \-\-preserve option is limited by the os python |
|
|
|
module on POSIX systems. Currently, python only returns timestamps in float |
|
|
|
format, which is a smaller precision than what POSIX provides. Progress on this |
|
|
|
issue can be seen at http://bugs.python.org/issue11457. |

Timestamps preservation with \fB\-\-preserve\fP option is limited by the |

.PP |
|
|
|
The \fB\-\-preserve\fP option cannot currently be used without an attribute |
|
|
|
list (\fBgcp \-\-preserve foo bar\fP will behave as \fBgcp \-\-preserve=foo |
|
|
|
bar\fP). Use the \fB\-p\fP switch instead. |
|
|
|
.SH NOTE ON NTFS |
|
|
|
NTFS will not enforce the same file name limitations than FAT, but files that |
|
|
|
would not be accepted on a FAT filesystem will still cause problems on Windows. |
|
|
|
Hence, it is recommended to use \-\-fix-filenames=force when copying to NTFS |
|
|
|
(when Windows compatibility is desired, anyway). |
