pipe-checksum(1) General Commands Manual pipe-checksum(1) NAME pipe-checksum -- Write stdin to file and create a file with the check- sum of the data SYNOPSIS pipe-checksum file [-D MD5|SHA1|SHA256|SHA384|SHA512|... |- --digest MD5|SHA1|SHA256|SHA384|SHA512|...] pipe-checksum [-h | --help] pipe-checksum [--version] DESCRIPTION pipe-checksum writes all data from standard input into a given file "<file>". Furthermore, it computes the checksum of the data and writes it to a new file "<file>.checksum". The used message digest algorithm can be configured, it defaults to SHA256. The checksum format is BSD- style checksum format, as written for example by the sha256sum tool. Therefore, any tool supporting this format can be used for comparison. ARGUMENTS The following arguments may be provided: -D MD5|SHA1|SHA256|SHA384|SHA512|... | --digest MD5|SHA1|SHA256|SHA384|SHA512|... Sets the message digest. Any digest supported by the underlying libcrypto library is possible. Calling pipe-checksum with no options, or with invalid digest, provides the list of all sup- ported digests. Default: SHA256. -h | --help Prints command help. --version Prints program version.
