| 9 * This source code is released into the public domain. It is provided on an | |
| 10 * as-is basis and no responsibility is accepted for its failure to perform | |
| 11 * as expected. It is worth at least as much as you paid for it! | |
| 12 * | |
| 13 * tee.c - pipe fitting | |
| 14 * | |
| 15 * tee reads stdin, and writes what it reads to each of the specified | |
| 16 * files. The primary reason of existence for this version is a quick | |
| 17 * and dirty implementation to distribute with Vim, to make one of the | |
| 18 * most useful features of Vim possible on OS/2: quickfix. | |
| 19 * | |
| 20 * Of course, not using tee but instead redirecting make's output directly | |
| 21 * into a temp file and then processing that is possible, but if we have a | |
| 22 * system capable of correctly piping (unlike DOS, for example), why not | |
| 23 * use it as well as possible? This tee should also work on other systems, | |
| 24 * but it's not been tested there, only on OS/2. | |
| 25 * | |
| 26 * tee is also available in the GNU shellutils package, which is available | |
| 27 * precompiled for OS/2. That one probably works better. | |
