no slash we already did that).
Additionally, suppress the error message for command -v for files with a slash.

This allows script compatibility with Linux, whose
"hostname" is the same as BSD "hostname -s".
With this change, "hostname -f" is the same on
both systems.

issue a syntax error immediately but save the information that it is erroneous
for later when the parameter expansion is actually done. This means eg. "false
&& ${}" will not generate an error which seems to be required by POSIX.
Include the invalid parameter expansion in the error message (sometimes
abbreviated with ... because recovering it would require a lot of code).

instead of removing the file and issue a warning about
the removal, do not do any operation at all in case -P
is specified when the dinode has hard links.
With -f and -P specified together, we assume that the
user wants rm to overwrite the contents of the file
and remove it (destroy the contents of file but leave
its hard links as is).
The reason of doing it this way is that, in case where
a hard link is created by a malicious user (currently
this is permitted even if the user has no access to the
file). Losing the link can potentially mean that the
actual owner would lose control completely to the user
who wants to obtain access in a future day.

loss, which is usually undesired.

current implementation of df(1) is does not properly format the output under
certain conditions. Right now -kP and -Pk are not the same thing. Further,
when we set the BLOCKSIZE environment variable, we use "1k" instead of "1024",
making the header display incorrectly.
To quote the specification:
"When both the -k and -P options are specified, the following header line
shall be written (in the POSIX locale):
"Filesystem 1024-blocks Used Available Capacity Mounted on\n"
- If -P has been specified, check to make sure that -k has not already been
specified, if so, simply break instead of clobbering the previous blocksize
- Use 1024 instead of 1k to make the header POSIX compliant
