.SH DESCRIPTION

This manual page documents briefly the

|
|
command.

\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.
|
|

|
|
A summary of options is included below.
|
|
.SS "General options"

.B \-\-preserve=PRESERVE
|
|

|
that timestamps preservation has some limits, see section LIMITS.
|

|
.B \-v, \-\-verbose
|
|
Display what is being done.
|
|
.SS "Sources saving"
|
|
.TP
|
|
.B \-\-sources\-save=SOURCES_SAVE
|
|
Save the list of source files in a list named SOURCES_SAVE.
|
|
.TP
|
|
.B \-\-sources\-replace=SOURCES_REPLACE
|
|
Save the list of source files in a list named SOURCES_REPLACE and
|
|
replace it if it already exists.
|
|
.TP
|
|
.B \-\-sources\-load=SOURCES_LOAD
|
|
Reuse the list of source file named SOURCES_LOAD.
|
|
.TP
|
|
.B \-\-sources\-del=SOURCES_DEL
|
|
Delete the list of source files named SOURCES_DEL.
|
|
.TP
|
|
.B \-\-sources\-list
|
|
List the names of source file lists.
|
|
.TP
|
|
.B \-\-sources\-full\-list
|
|
List the names of source file lists, including their content.
|
|
.SH EXIT STATUS
|
|
The exit status can be:
|
|
.IP \[bu] 2
|
|
\fB0\fP if files have been copied correctly or if another instance of gcp is already running and will do the copy.
|
|
.IP \[bu]
|
|
\fB1\fP if at least one file has not been copied, or if something went wrong.
|
|
.IP \[bu]
|
|
\fB2\fP if all files have been copied but with some issues
|
|
.SH LIMITS
|
|
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.
