teego

golang tee

You can choose ignore ANSI Control Sequences or not.

how to use this tool

• stdout & stderr -> color
• file output -> no color

$ cat main.c | grep --color=always func | teego tmp.txt
$ ls --color=always | teego tmp.txt
$ ccat -C=always main.c | teego tmp.txt

TODO

• flagで通常のteeのような挙動に
• solve ErrTooLong = errors.New("bufio.Scanner: token too long")
  • see: Goのbufio.Scannerは入力データの1行の長さが一定以上になるとスキャンをやめてしまう - ぬいぐるみライフ？

TEE(1)                    BSD General Commands Manual                   TEE(1)

NAME
     tee -- pipe fitting

SYNOPSIS
     tee [-ai] [file ...]

DESCRIPTION
     The tee utility copies standard input to standard output, making a copy in zero or more files.  The output is unbuffered.

     The following options are available:

     -a      Append the output to the files rather than overwriting them.

     -i      Ignore the SIGINT signal.

     The following operands are available:

     file  A pathname of an output file.

     The tee utility takes the default action for all signals, except in the event of the -i option.

     The tee utility exits 0 on success, and >0 if an error occurs.

STANDARDS
     The tee function is expected to be POSIX IEEE Std 1003.2 (``POSIX.2'') compatible.
