   sha1sum    ( 1 )

вычислить и проверить дайджест сообщения SHA1 (compute and check SHA1 message digest)

Имя (Name)

sha1sum - compute and check SHA1 message digest

Синопсис (Synopsis)

sha1sum [OPTION]... [FILE]...

Описание (Description)

Print or check SHA1 (160-bit) checksums.

With no FILE, or when FILE is -, read standard input.

-b, --binary read in binary mode

-c, --check read SHA1 sums 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 FIPS-180-1. When checking, the input 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.


Ошибки (баги) (Bugs)

Do not use the SHA-1 algorithm for security related purposes.
       Instead, use an SHA-2 algorithm, implemented in the programs
       sha224sum(1), sha256sum(1), sha384sum(1), sha512sum(1), or the
       BLAKE2 algorithm, implemented in b2sum(1)
