anthraxx / dfrs Goto Github PK

This is great; good work :)

Just a suggestion / request, but... a du -hcs * equivalent, durs, would be really nice. Essentially for something like kdirstat, but at the command line.

If enough of the code was shared, it might make sense to have the same executable behave differently based on its argv[0] name (durs or dfrs), as some other tools (whatis, mtools, gawk, etc.) do.

Edit: never mind. inspired by this, I found a few du equivalents on crates.io, like parallel-disk-usage :)

[yuri@yv /usr/ports/sysutils/dfrs]$ dfrs 
Error: No such file or directory (os error 2)

It doesn't say what file it was trying to open.
It was actually /proc/self/mounts.

 15940 dfrs     NAMI  "/proc/self/mounts"
 15940 dfrs     RET   openat -1 errno 2 No such file or directory

sysctl kern.disks reads mounted disks on FreeBSD.

dfrs is kinda bad-color-noisy with default tresholds:

so is duf, for example:

but duf has a flag to modify them:

How duf does it is however still not perfect, my complex suggestion to tackle this properly is here: Canop/dysk#18 (comment)

Hi dear dev⋅s !

Can you please add the ability to list mount options (or tell us if you plan to release this feature since the MOUNT structure has the mnt_opts element, which seems to imply that it is planned) as seen in parse_mount() test and like the dfctool do :
file : dfrs/src/mount.rs:12 (for the struct → :17) :

#[derive(Clone)]
pub struct Mount {
    pub mnt_fsname: String,
    pub mnt_dir: String,
    pub mnt_type: String,
    pub mnt_opts: String,
    pub mnt_freq: i32,
    pub mnt_passno: i32,
    pub capacity: u64,
    pub free: u64,
    pub used: u64,
    pub statfs: Option<nix::sys::statfs::Statfs>,
}

file : dfrs/src/mount.rs:166 (for the test) :

 #[test]
    fn parse_mounts() {
        let file = r#"sysfs /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0
proc /proc proc rw,nosuid,nodev,noexec,relatime,hidepid=2 0 0

Thank you for this great tool and to contrib to the rustutils'vers 👍

df has --total. Could be interesting to have this in dfrs. Together with the better defaults of dfrs, it would show the net storage with ``

$ df --help | grep total
      --total           elide all entries insignificant to available space,
                          and produce a grand total
field names are: 'source', 'fstype', 'itotal', 'iused', 'iavail', 'ipcent',
# df --total -T / /boot /dev 
Filesystem                  Type     1K-blocks      Used Available Use% Mounted on
/dev/mapper/nvme0n1p5_crypt btrfs    478497792 158877508 318601596  34% /
/dev/nvme0n1p1              btrfs       487424    188340    240604  44% /boot
udev                        devtmpfs  16161996         0  16161996   0% /dev
total                       -        495147212 159065848 335004196  33% -

To keep things simple, maybe --total should be limited to fs on actual block devices and not tmpfs nor udev?

When using dfrs, ZFS datasets/filesystems aren't displayed unless dfrs -aa is used. However, -aa also displays a lot of filesystems that probably aren't useful to look at, like tmpfs, hugetlbfs etc.

Assume a CIFS mount at /mnt/x, running dfrs /mnt/x results in

dfrs /mnt/x
Filesystem          Type                       Used% Avail   Used   Size Mounted on
/xxxxxx/root        ext4 ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇╍╍  88.8% 52.4G 414.3G 466.7G /

which is equivalent to dfrs / while df -h shows usage of the filesystem at //cifshost/folder.

currently on Ubuntu 22.04 and currently have several snap package installed. When using dfrs (0.0.7), all looped devices for every snap application shows up in the listing which is rather useless since they all show 100% utilization. Was wondering if squashfs filesystems could be added to the list of filesystems that are normally hidden unless -a or -aa is used to show them.
