I had a quick look into the sources and functionality ([1]) and this is 
a combination of a C tool for each functionality and common 
functionality and Perl wrappers around it.

[1]: https://src.fedoraproject.org/rpms/edg-gridftp-client

Not knowing about this toolset I did create something similar with 
similar functionality some years ago and wrapped UberFTP with Bash 
scripts instead. It's called gtools and is a multicall script with all 
functionality included in a Bash "library" and the main script with 
symlinks to the specific functions (like `gcat`, `grm`, `gmv`, etc.). 
See [2] and [3] for details.

[2]: https://github.com/fr4nk5ch31n3r/gtransfer/blob/master/bin/gtools.bash

[3]: 
https://github.com/fr4nk5ch31n3r/gtransfer/blob/master/lib/gtransfer/gridftp.bashlib

I included it in the gtransfer repo, but it will actually work w/o 
gtransfer present. Apart from functionality similar - maybe not in all 
details - to the edg-gridftp-client it can use some additional features 
useful on the command line:

* host aliases ([4]) to shorten lengthy gsiftp:// URLs (incl. Bash 
completion of aliases) - in short you can replace any 
"gsiftp://host.domain.tld:<PORT>" part with something like "alias:"

* browsing remote paths directly on the command line (via Bash completion)

[4]: 
https://github.com/fr4nk5ch31n3r/gtransfer/blob/master/share/doc/host-aliases.md

It should be maybe checked if functionality is equal everywhere, but if 
it is, matching symlinks with EDG names could be created to match the 
EDG client's commands. If we decide for a replacement, it will only 
require the maintenance of some Bash scripts, as we already maintain 
UberFTP, compared to C and Perl code. Judging by the amount of work I 
put into this since its creation, I'd say the maintenance effort is near 
zero.

But I assume the edg-gridftp-client code doesn't need much maintenance 
either.

Personally I don't have a preference. Actually I'm usually in favor to 
keep useful things around. And the C code of the edg-gridftp-client 
being a useful example to show what can be done with the GCT, already 
qualifies for that in my eyes. Even if we just include it under the 
umbrella of the GridCF and make it a public archive later to keep it at 
a known place would be useful in my eyes.

Cheers,
Frank
