Add a missing dash to the `--total` argument applied in the
`test_df_output` test case. Before this commit, the argument `-total`
was treated as a path argument. After this commit, `--total` is
treated as a command-line option that causes the total file usage to
be displayed.
* hashsum: add --no-names option from official b3sum tool
The official b3sum tool has a --no-names option for only printing the
hashes, omitting the filenames. This is quite handy when used from
scripts because it spares the postprocessing with "cut" or "awk".
Since the installed b3sum symlink would also serve as a drop-in for the
official tool, the --no-names option is expected to exist for
compatibility.
Add a --no-names option not only for b3sum but for hashsum in general
(and maybe GNU coreutils will also feel inspired to add this option).
Closes https://github.com/uutils/coreutils/issues/3360
Change formula from: "Used/Size * 100" to "Used/(Used + Avail) * 100".
This formula also works if "Used" and "Avail" do not add up to "Size",
which is the case if there are reserved disk blocks.
When doing
ln b b~
ln -f --b=simple a b
First, we create a backup of b
Then, we force the override of a => b but we make sure that the backup is
done.
So, we had a bug in the ordering of the actions.
we were first removing b. Therefore, losing the capability to do a backup of this.

Previously, individual file sizes were used to compute the number width, which
would cause misalignment when the total has a greater number of digits, and is
different from the behavior of GNU wc

"df --output ." was treated as "df --output=." and hence "." was
interpreted as a column name. With this commit, "." is treated as
an argument on its own.
Fixes#3324
Print a usage error when duplicat column names are specified to the
`--output` command-line argument. For example,
$ df --output=source,source
df: option --output: field ‘source’ used more than once
Try 'df --help' for more information.
Implement the "File" column in the `df` output table. Before this
commit, a blank entry appeared in the "File" column for each
row. After this commit, a "-" entry appears when `df` is run with no
positional arguments and the filename appears when run with positional
arguments. For example:
$ touch a b c && df --output=target,file a b c
Mounted on File
/ a
/ b
/ c
Produce a usage error on an invalid signal argument. For example,
$ timeout --signal=invalid 1 sleep 0
timeout: 'invalid': invalid signal
Try 'timeout --help' for more information.
Return an error when a negative interval is provided as the argument
to `uucore::parse_time::from_str()`, since a `Duration` should only be
non-negative.
Fix a bug in the behavior of `split -e -n NUM` when the input file is
empty. Previously, it would panic due to overflow when subtracting 1
from 0. After this change, it will terminate successfully and produce
no output chunks.
Use `Duration::saturating_mul()` to avoid a panic due to overflow in
`uucore::parse_time::from_str()`. This change prevents panic on very
large arguments to timeout and sleep.
These are the first half of changes needed to pass the dd/bytes.sh tests:
- Add iseek and oseek options (additive with skip and seek options)
- Implement tests for the new flags, matching those from dd/bytes.sh
Implement distributing lines of a file in a round-robin manner to a
specified number of chunks. For example,
$ (seq 1 10 | split -n r/3) && head -v xa[abc]
==> xaa <==
1
4
7
10
==> xab <==
2
5
8
==> xac <==

Previously, given 'cp -P a b', where 'a' and 'b' were both symlinks, cp
would end up replacing the target of 'b'.

Fix a bug where `timeout --preserve-status` was not correctly
preserving the status code of the child process if it timed out. When
that happens, the status code of the child process is considered to be
the signal number (in this case, `SIGTERM`). The exit status of
`timeout` is then 128 plus the numeric code associated with `SIGTERM`.
* Adds support for mount path prefix matching and input path
canonicalization
- Sorts mount paths in reverse lexicographical order
- Canonicalize all paths and clear invalid paths
- Checking of mount path prefix matches input path
Implement the `--line-bytes` option to `split`. In this mode, the
program tries to write as many lines of the input as possible to each
chunk of output without exceeding a specified byte limit. The new
`LineBytesChunkWriter` struct represents this functionality.
Implement the `--output` command-line argument, which allows
specifying an exact sequence of columns to display in the output
table. For example,
$ df --output=source,fstype | head -n3
Filesystem Type
udev devtmpfs
tmpfs tmpfs
(The spacing does not exactly match the spacing of GNU `df` yet.)
Fixes#3057.
Correct the column header printed by `df` when the `--block-size`
argument has a value that is a multiple of 1024. After this commit,
the header looks like "1K" or "4M" or "117G", etc., depending on the
particular value of the block size. For example:
$ df --block-size=1024 | head -n1
Filesystem 1K-blocks Used Available Use% Mounted on
$ df --block-size=2048 | head -n1
Filesystem 2K-blocks Used Available Use% Mounted on
$ df --block-size=3072 | head -n1
Filesystem 3K-blocks Used Available Use% Mounted on
$ df --block-size=4096 | head -n1
Filesystem 4K-blocks Used Available Use% Mounted on
Add support for the `--total` option to `df`, which displays the total
of each numeric column. For example,
$ df --total
Filesystem 1K-blocks Used Available Use% Mounted on
udev 3858016 0 3858016 0% /dev
...
/dev/loop14 63488 63488 0 100% /snap/core20/1361
total 258775268 98099712 148220200 40% -
Implement `-n l/k/N` option, where the `k`th chunk of the input file
is written to stdout. For example,
$ seq -w 0 99 > f; split -n l/3/10 f

Add support for `split -n l/NUM`. Previously, `split` only supported
`-n NUM`, which splits a file into `NUM` chunks by byte. The `-n
l/NUM` strategy splits a file into `NUM` chunks without splitting
lines across chunks.
https://github.com/uutils/coreutils/pull/3084 (2a333ab391) had some
missing coverage and was merged before I had a chance to fix it.
This PR adds some coverage / improved error messages that were missing
from that previous PR.
If `conv=block,sync` command-line arguments are given and there is at
least one partial record read from the input (for example, if the
length of the input is not divisible by the value of the `ibs`
argument), then output an extra block of `cbs` spaces.
For example, no extra spaces are printed in this example because the
input is of length 10, a multiple of `ibs`:
$ printf "012\nabcde\n" \
> | dd ibs=5 cbs=5 conv=block,sync status=noxfer \
> && echo $
012 abcde$
2+0 records in
0+1 records out
But in this example, 5 extra spaces are printed because the length of
the input is not a multiple of `ibs`:
$ printf "012\nabcdefg\n" \
> | dd ibs=5 cbs=5 conv=block,sync status=noxfer \
> && echo $
012 abcde $
2+1 records in
0+1 records out
1 truncated record
The number of spaces printed is the size of the conversion block,
given by `cbs`.
