So a sysadmin who logs on to a server (which uses btrfs) over plain SSH should need to install a good chunk of X11 plus a load of support libraries on the server, plus have a X11 server on the machine they are connecting from, simply to get a tabular view of the disk space? That _might_ fly in a strictly *nix environment. In a mixed *nix/Windows (and maybe even throw in some Mac OS X) environment, not necessarily as much so. And what about the sysadmin on the road who logs on using a smartphone SSH client to get a quick overview of the disk usage situation because they received an alert that disk space is starting to run low? It appears to me that what is being discussed here is, to some extent, an edge case of use of a file system feature that hasn't even been implemented yet, but rather is only planned. Like Martin pointed out, scripts should not parse meant-for-human-consumption output anyway, and beyond trivial greps and that kind of parsing, tabular data by design lends itself rather poorly to script parsing anyway. I would personally really prefer a tabular view that perhaps does not show _all_ details when no explicit parameters are given, and a "--dump" or similar that will give a fuller data dump that might lend itself better to parsing by other tools for a more thorough presentation. The data is all right there; it's basically a matter of deciding how much of it to show by default. -- Michael Kjörling • http://michael.kjorling.se • mich...@kjorling.se “People who think they know everything really annoy those of us who know we don’t.” (Bjarne Stroustrup) -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
