gcp is a file copier, loosely inspired from cp, but with high level
functionalities such as:
- Progress bar.
- gcp keeps copying even when there is an issue: it just skips the file,
logs an error and goes on.
- Logging: gcp writes what it’s doing to a log file; this allows you to
know which files were effectively copied.
- Fixing file names to be compatible with the target filesystem (e.g.
removing incompatible chars like
* on FAT).
- Queue: if you launch a copy when another copy is already running, the
files are added to the first queue; this optimizes hard drive head movement
and filesystem fragmentation.
- Files saving: you can keep track of the files you have copied, and copy
them again later (useful when, for example, you copy some free music to your
friends on a regular basis).
- gcp will be approximately option-compatible with cp (approximately
because the behaviour is not exactly the same, see below).
WARNING: gcp is at a relatively early stage of development, use at your own
How to use it?
Pretty much like cp (see
Please note that the behaviour is not exactly the same as cp’s, even if gcp
aims to be option-compatible. Mainly, the destination filenames can be modified
gcp doesn’t implement all the options from cp yet, but it’s a long-term goal.
The log file is aimed to be used by gcp itself, buts remains human-readable. It
is located in
3 states are used:
- OK means the file was copied and all operation were successful.
- PARTIAL means the file was copied, but something went wrong (file
permissions could not be preserved, file name had to be changed, etc.).
- FAILED: the file was not copied.
After the state, a list of things that went wrong is shown, separated by “, “.
Here are some ideas for future developments:
- handle XDG
- copy queue management (moving copy order)
- advanced console interface
- notification (XMPP and maybe email) when a long copy is finished
- retry for files that were not correctly copied
- badly encoded unicode filenames fix
- file copy integrity check
And in an even more distant future:
- graphic interface
- desktop (Kde, Gnome, XFCE…) integration
- distant copy (FTP)
- basic server mode, for copying files on network without the need of NFS or
other heavy stuff

gcp uses ProgressBar, a class

This heavily used library is used here for the main loop, event catching, and
for DBus. Get it at https://developer.gnome.org/glib/.
This excellent IPC is ut the heart of gcp. Get more information at
Python and its amazing standard library:
gcp was coded quickly for my own needs thanks to this excellent and efficient
language and its really huge standard library. Python can be download at
