shasum: Calculate the SHA1 checksum for one or more files.

shasum

$ shasum ${filename1 filename2 ---}

try on your machine

The shasum command in this context is used to calculate checksums or hash values of one or more files. The ${filename1 filename2 ---} part of the command is a placeholder for the names of files you want to calculate the checksum for.

Here's how the command works:

shasum: Starts the shasum command, which is typically used to compute SHA checksums.
${filename1 filename2 ---}: This part is not the actual command; it is a placeholder for the file or files you want to calculate the checksum for. ${filename1 filename2 ---} indicates that you can pass multiple filenames to the shasum command, separated by spaces. The --- is used as an optional way of indicating the end of the files and is used to handle filenames that start with a hyphen (-).

To use this command, you should replace ${filename1 filename2 ---} with the actual filenames you want to compute the checksum for, for example:

shasum file1.txt file2.txt

This will calculate the SHA checksums for file1.txt and file2.txt and display the results on the console.
