Стандартный вывод (Stdout)
If the -d option is used with the -v option, the standard output
format shall be:
"d - %s\n", <file>
where file is the operand specified on the command line.
If the -p option is used with the -v option, ar shall precede the
contents of each file with:
"\n<%s>\n\n", <file>
where file is the operand specified on the command line, if file
operands were specified, and the name of the file in the archive
if they were not.
If the -r option is used with the -v option:
* If file is already in the archive, the standard output format
shall be:
"r - %s\n", <file>
where <file> is the operand specified on the command line.
* If file is not already in the archive, the standard output
format shall be:
"a - %s\n", <file>
where <file> is the operand specified on the command line.
If the -t option is used, ar shall write the names of the files
in the archive to the standard output in the format:
"%s\n", <file>
where file is the operand specified on the command line, if file
operands were specified, or the name of the file in the archive
if they were not.
If the -t option is used with the -v option, the standard output
format shall be:
"%s %u/%u %u %s %d %d:%d %d %s\n", <member mode>, <user ID>,
<group ID>, <number of bytes in member>,
<abbreviated month>, <day-of-month>, <hour>,
<minute>, <year>, <file>
where:
<file> Shall be the operand specified on the command line, if
file operands were specified, or the name of the file
in the archive if they were not.
<member mode>
Shall be formatted the same as the <file mode> string
defined in the STDOUT section of ls, except that the
first character, the <entry type>, is not used; the
string represents the file mode of the file in the
archive at the time it was added to or replaced in the
archive.
The following represent the last-modification time of a file when
it was most recently added to or replaced in the archive:
<abbreviated month>
Equivalent to the format of the %b conversion
specification format in date.
<day-of-month>
Equivalent to the format of the %e conversion
specification format in date.
<hour> Equivalent to the format of the %H conversion
specification format in date.
<minute> Equivalent to the format of the %M conversion
specification format in date.
<year> Equivalent to the format of the %Y conversion
specification format in date.
When LC_TIME does not specify the POSIX locale, a different
format and order of presentation of these fields relative to each
other may be used in a format appropriate in the specified
locale.
If the -x option is used with the -v option, the standard output
format shall be:
"x - %s\n", <file>
where file is the operand specified on the command line, if file
operands were specified, or the name of the file in the archive
if they were not.
