//! //! copy standard input to each files and standard output. //! //! ```text //! Usage: //! aki-xtee [options] [<file>...] //! //! this is like the linux command `tee`. //! copy standard input to each <file>, and to standard output. //! automatic discovery file type: plain, gz, xz and zst. //! //! Options: //! -a, --append <file> append to the <file>, do not overwrite [unimplemented] //! -p, --pipe-out <num> write to pipe <num> [unimplemented] //! //! -H, --help display this help and exit //! -V, --version display version information and exit //! //! Argument: //! <file> utf-8 encoded plain text file, //! gzip compressed file at the end with '.gz', //! xz2 compressed file at the end with '.xz', //! zstd compressed file at the end with '.zst'. //! //! Examples: //! You can simple use. Just arrange the files: //! cat in-file | aki-xtee file1 file2.gz file3.xz file4.zst //! ``` //! //! # Examples //! //! ### Command line example 1 //! //! output "ABCDEFGH" to standard output and plain text file. //! ```text //! echo "ABCDEFGH" | aki-xtee out/plain.txt //! ``` //! result output : //! ```text //! ABCDEFGH //! ``` //! //! output "ABCDEFGH" to standard output and gzip text file. //! ```text //! echo "ABCDEFGH" | aki-xtee out/gztext.txt.gz //! ``` //! result output : //! ```text //! ABCDEFGH //! ``` //! //! output "ABCDEFGH" to standard output and xz text file. //! ```text //! echo "ABCDEFGH" | aki-xtee out/xztext.txt.xz //! ``` //! result output : //! ```text //! ABCDEFGH //! ``` //! //! output "ABCDEFGH" to standard output and zstd text file. //! ```text //! echo "ABCDEFGH" | aki-xtee out/xztext.txt.zst //! ``` //! result output : //! ```text //! ABCDEFGH //! ``` //! //! ### Command line example 2 //! //! copy input to plain text file, gzip text file, xz text file and zstd text file. //! ```text //! aki-xtee out/plain.txt out/gztext.txt.gz out/xztext.txt.xz out/zstext.txt.zst //! ``` //! //! ### Library example //! //!
