Usage: sha1sum [OPTION]... [FILE]...
|
||
|
|
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
|
||
|
|
-t, --text read in text mode (default)
|
||
|
|
Note: There is no difference between binary and text mode option on GNU system.
|
||
|
|
|
||
|
|
The following three options are useful only when verifying checksums:
|
||
|
|
--quiet don't print OK for each successfully verified file
|
||
|
|
--status don't output anything, status code shows success
|
||
|
|
-w, --warn warn about improperly formatted checksum lines
|
||
|
|
|
||
|
|
--help display this help and exit
|
||
|
|
--version stampa le informazioni sulla versione ed esce
|
||
|
|
|
||
|
|
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 character indicating type (`*' for binary, ` ' for
|
||
|
|
text), and name for each FILE.
