In the default configuration add 2 bindings which has been requested by
many during the HEADSUP discussion:
* csh like arrow history navigation
* ctrl-arrow to jump from word to words
Add an alias to make the history command exist as an alias to fc -l.
Make freebsd-version(1) support jails by adding the -j flag which takes

When there are many matches, find the longest common substring starting
from the beginning of each command and use that to replace input.
As an example: on my system, llv<tab> will be autocompleted to llvm-
and another <tab> will print all matching llvm commands.
Until this change, any bindings set in histedit() were lost on calls to
bindcmd().
Only bind -e and bind -v call libedit's keymacro_reset(). Currently you
cannot fool libedit/map.c:map_bind() by trying something like bind -le
as when p[0] == '-', it does a switch statement on p[1].
Allows capitalizing the background color character to enable an
underline instead of bold, capitalizing the foreground color char will
still do bold.

When multiple matches are found, we keep the provided string on the
input line and print unique matches as suggestions.
But the multiple matches might be the same command found in different
directories, so we should deduplicate the matches first and then decide
whether to autocomplete the command or not, based on the number of
unique matches.
in emacs mode ^W should delete the previous word by default
Note that upstreaming this change directly into libedit is in process.

As 257886 reports, if ls(1) is built with WITHOUT_LS_COLORS="YES", it
issues a warning whenever COLORTERM is non-empty. The warning is not
useful, so I thought to remove it, but as Ed pointed out, we may want
to have a way to determine whether a particular copy of ls has been
compiled with color support or not.
Therefore move the warnx() call to the getopt loop in
a WITHOUT_LS_COLORS build to fire when the user asks for colored output.

Implement persistent history storage:
the strategy is simple at start: loads the existing .sh_history file
at exit dump it.
The implementation respects the HISTFILE variable and its POSIX
definition: ~/.sh_history is used if HISTFILE is not set.
to avoid sh to create the history file, set HISTSIZE to 0 or HISTFILE to

The following situation can trigger the deadlock:
1) Long time ago a_service was started through rc.d
2) We want to restart a_service and issue service a_service restart
3) rc.subr reads current process PID (via file or process),
sends TERM signal and runs pwait with PID harvested
4) a_service process dies very quickly so it's PID becomes available.
It is possible that while original process was running,
PID counter overflowed and pwait got assigned a_service's PID.
This patch ignores pid(s) to wait that are equal to pwait PID.

PR252358 reported a serious performance problem when
copying a large non-sparse file on a UFS file system.
This problem seems to have been caused by a large
number of SEEK_HOLE operations, with one done
for each copy_file_range(2) call.
This patch modifies cp(1) to use a large (SSIZE_MAX)
len argument, reducing the number of system calls
and resolving the performance issue.
While here, convert the type of the "rcount" from "int"
to "ssize_t" so that it is consistent with that returned
by both read(2) and copy_file_range(2).

This change has been motivated by a mail from bde sent in 2015 in
which he mentioned inappropriate use of sscanf() in 3 programs in
/bin.
This change removes the potential mismatch of the types of the return
values and the variable width specified in the scan pattern. While
there was no issue with the patterns and types used, the new code is
simpler and more efficient.
The previous version normalized the width list (replaced empty fields
with "0") just to be able to use sscanf() on the string.
It is much simpler to just parse the string as-is.
The clearing of f_notabs is preserved for the case that less than 9
width values have been defined, but I do not understand the rationale
for this particular condition. E.g., LS_COLWIDTHS="::::::::" will be
counted as 9 defined fields (may clear f_notabs) but is no different
fron LS_COLWIDTHS="" with regard to the field width (and that does not
clear f_notabs, since there are less than 9 fields).
