This utility uses the Core::DirIterator facility which in turn uses the
get_dir_entries syscall. Therefore, this utility lets us to view the
actual values for inode numbers, and entry type value for directory
entries.
As the newly created function has been also applied to printing the
number of matched file lines, file names will now also be colored
with the `--count` option set. :^)
The "dependency" lines really belong to the main port entry, it doesn't
make sense logically to represent them separately and handling them
together will also allow easier dependency management later on. This
commit greatly simplifies the port database parsing to facilitate this,
and removes the -d option from the command line. Instead, ports are
listed with their dependencies, if they have any.
This behaves identically to the `-exec` option but prompts the user
for confirmation before executing the specified command.
A command is executed if a line beginning with 'y' or 'Y' is entered
by the user. This matches the behavior of `find` on Linux and FreeBSD
when using the POSIX locale.
The `-maxdepth` option limits the number of levels `find` will descend
into the file system for each given starting point.
The `-mindepth` option causes commands not to be evaluated until the
specified depth is reached.
These return true if the last modification time, last access time or
creation time of a file is greater than the given reference file.
If the `-L` option is in use and the given reference file is a
symbolic link then the timestamp of the file pointed to by the
symbolic link will be used.
The argument supplied to the `-size` option may now be one of the
following suffixes:
* b: 512-byte blocks. This is the default unit if no suffix is used.
* c: bytes
* w: two-byte words
* k: kibibytes (1024 bytes)
* M: mebibytes (1024 kibibytes)
* G: gibibytes (1024 mebibytes)
Sizes are rounded to the specified unit before comparison. The unit
suffixes are case-sensitive.
This changes the default behavior, so that, by default, color codes,
hyperlinks and additional spacing are only emitted when standard
output is connected to a terminal.
The default coloring behavior can be overridden with the `--color`
option. Valid arguments for this option are: 'always', 'never' and
'auto' (default).
This is only possible if listing an entire directory, because the LibC
readdir function will return the raw inode number in each struct dirent,
therefore allowing to print it as well.
This option allows the user to change which colums are displayed
by giving comma or space separated list of column format specifiers.
A column format specifier is of the form: `COLUMN_NAME[=COLUMN_TITLE]`.
Where `COLUMN_NAME` is any of: uid, pid, ppid, pgid, sid, state, tty,
or cmd. Specifying a `COLUMN_TITLE` will change the name shown in the
column header.
`COLUMN_TITLE` may be blank. If all given column titles
are blank, the header is omitted.
Previously, it was assumed that only one filtering option, such as
`-u` or `-p` would be used at a time. With this PR, processes are now
shown if they match any of the specified filters.
Describe how to use the two new context and unified format options in
the diff utility. Also change the example comparison of two files so
they contain more lines as that is much more interesting (and useful).
This small utility is something we probably needed for a very long
time - a way to print memory statistics in an elegant manner.
This utility opens /sys/kernel/memstat, reads it and decode the values
into human readable entries, possibly even into human-readable sizes.
Use LibCore ArgsParser to parse the parameters instead of using the raw
strings from the argv (Main::Arguments) array.
Also, use indicative names for variables in the code so the utility code
is more understandable.
This change was a long time in the making ever since we obtained sample
rate awareness in the system. Now, each client has its own sample rate,
accessible via new IPC APIs, and the device sample rate is only
accessible via the management interface. AudioServer takes care of
resampling client streams into the device sample rate. Therefore, the
main improvement introduced with this commit is full responsiveness to
sample rate changes; all open audio programs will continue to play at
correct speed with the audio resampled to the new device rate.
The immediate benefits are manifold:
- Gets rid of the legacy hardware sample rate IPC message in the
non-managing client
- Removes duplicate resampling and sample index rescaling code
everywhere
- Avoids potential sample index scaling bugs in SoundPlayer (which have
happened many times before) and fixes a sample index scaling bug in
aplay
- Removes several FIXMEs
- Reduces amount of sample copying in all applications (especially
Piano, where this is critical), improving performance
- Reduces number of resampling users, making future API changes (which
will need to happen for correct resampling to be implemented) easier
I also threw in a simple race condition fix for Piano's audio player
loop.
