gsha1sum:tldr:ac398

The command you mentioned is:

tldr -p linux sha1sum

This command has two parts, tldr and sha1sum, and the -p linux flag is used as an option for tldr.

1. tldr: TLDR (Too Long; Didn't Read) is a command-line utility that provides succinct and practical examples of how to use various commands. It's designed to quickly give you a summary of a command's usage.

2. sha1sum: This command is used to calculate the SHA-1 hash value of a file. The SHA-1 algorithm generates a fixed-size hash code (usually 160-bit) that is commonly used for data integrity purposes to ensure that the file has not been tampered with.

The -p linux flag is specific to tldr and used to specify the platform or operating system for which you want to see the command summary. In this case, it's set to "linux", indicating that you want the tldr summary for the sha1sum command on a Linux platform.

Putting it all together, the command tldr -p linux sha1sum would display a succinct summary of the sha1sum command's usage on a Linux platform using the tldr utility.
