sha224sum [OPTION]... [FILE]...
!subtitle:功能
计算或校验 SHA224 值。
!subtitle:类型
可执行文件（/usr/bin/sha224sum），属于 coreutils。
!subtitle:参数
OPTION 选项：
-b, --binary - 以二进制模式读取文件；类 UNIX 系统下始终是二进制模式
-c, --check - 从文件中读取 SHA224 值进行校验
--tag- 生成 BSD 风格的输出
-t, --text - 以文本模式读取文件；类 UNIX 系统下不存在文本模式，此选项无效
-z, --zero - 以空字符（\0）作为行的结尾，而不是换行符（\n）
--ignore-missing - 校验时忽略缺失的文件
--quiet - 校验时不打印成功的消息
--status - 校验时不打印任何消息；可以通过返回值检查是否成功
--strict - 校验时严格检查格式
-w, --warn - 校验时遇到格式不正确的行时产生警告
--help - 显示帮助
--version - 显示版本
FILE - 文件列表

NAME
sha224sum - compute and check SHA224 message digest
SYNOPSIS
sha224sum [OPTION]... [FILE]...
DESCRIPTION
Print or check SHA224 (224-bit) checksums.
With no FILE, or when FILE is -, read standard input.
-b, --binary
read in binary mode
-c, --check
read checksums from the FILEs and check them
--tag create a BSD-style checksum
-t, --text
read in text mode (default)
-z, --zero
end each output line with NUL, not newline, and disable file
name escaping
The following five options are useful only when verifying checksums:
--ignore-missing
don't fail or report status for missing files
--quiet
don't print OK for each successfully verified file
--status
don't output anything, status code shows success
--strict
exit non-zero for improperly formatted checksum lines
-w, --warn
warn about improperly formatted checksum lines
--help display this help and exit
--version
output version information and exit
The sums are computed as described in RFC 3874. When checking, the in‐
put should be a former output of this program. The default mode is to
print a line with: checksum, a space, a character indicating input mode
('*' for binary, ' ' for text or where binary is insignificant), and
name for each FILE.
Note: There is no difference between binary mode and text mode on GNU
systems.
