Section 1

• uu-shuf · Shuffle the input by outputting a random permutation of input lines. Each output permutation is equally likely. With no FILE, or when FILE is -, read standard input.
• uu-sleep · Pause for NUMBER seconds.
• uu-sort · Display sorted concatenation of all FILE(s). With no FILE, or when FILE is -, read standard input.
• uu-split · Create output files containing consecutive or interleaved sections of input
• uu-stat · Display file or file system status.
• uu-stdbuf · Run COMMAND, with modified buffering operations for its standard streams.
• uu-stty · Print or change terminal characteristics.
• uu-sum · Checksum and count the blocks in a file. With no FILE, or when FILE is -, read standard input.
• uu-sync · Synchronize cached writes to persistent storage
• uu-tac · Write each file to standard output, last line first.
• uu-tail · Print the last 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With no FILE, or when FILE is -, read standard input. Mandatory arguments to long options are mandatory for short options too.
• uu-tee · Copy standard input to each FILE, and also to standard output.
• uu-test · Check file types and compare values.

• uu-truncate · Shrink or extend the size of each file to the specified size.
• uu-tsort · Topological sort the strings in FILE. Strings are defined as any sequence of tokens separated by whitespace (tab, space, or newline), ordering them based on dependencies in a directed acyclic graph (DAG). Useful for scheduling and determining execution order. If FILE is not passed in, stdin is used instead.

• uu-vdir · List directory contents. Ignore files and directories starting with a '.' by default Mandatory arguments to long options are mandatory for short options too.
