A head clone written in Rust.
"head" is a command line utility which gives you the first n lines (default 10) of STDIN or a text file. It can also give you just the first c bytes of a file.
# Handle text from Stdin
cat /path/to/file | rhead -n 20
# Handle text in a file
rhead -n 1 /etc/passwd
Usage: rhead [OPTIONS] [FILE]
Arguments:
[FILE] The file to read from (optional)
Options:
-n, --number <NUMBER> The number of lines to print [default: 10]
-c, --chars <CHARS> The number of characters to print (optional) [default: 0]
-h, --help Print help
-V, --version Print version
Input data stream or input file MUST be valid UTF-8 otherwise it will be rejected. However, it is possible to output invalid UTF-8 data with -c because it operates on arbitrary number of bytes.
