是否有办法在没有产出缓冲的情况下管理军舰?
例如,
什么是使任何指挥的产出不受影响的一般性解决办法?
AFAIK,你可以不cks。 书写管道(或从管道读取)会自动转而全面缓冲,而你无法做到这一点: 只有在阅读/写一个终点站时才能使用“Line缓冲”(这是你想要的)。 令人 The笑皆是: 他们把一项方案与假肢连接起来,以便管道的其他工具能够按照直线缓冲方式从该终端读/做成。 整个问题在此阐述:
该网页还提出一些建议(上述“ug”),即使用<代码>unbuffer<>/code>。 或用<代码>LD_PRELOAD pull。
Try stdbuf, 包括在全球宇宙航行联合会的核心用途中,从而实际上也包含着任何持久性有机污染物的分解。 这使投入、产出和错误的缓冲长度达到零:
stdbuf -i0 -o0 -e0 command
The command unbuffer from the expect package disables the output buffering:
Ubuntu Manpage: unbuffer - unbuffer output
例常使用:
unbuffer hexdump file | ./my_script也可使用<条码>。 指示将<代码>hexdump-buffered>(hexdump)的输出推到一个假终点站,该终点站将trick到hexdump<>/code>,将其排入终端而不是管道。
# cf. http://unix.stackexchange.com/questions/25372/turn-off-buffering-in-pipe/
stty -echo -onlcr
script -q /dev/null hexdump file | ./my_script # FreeBSD, Mac OS X
script -q -c "hexdump file" /dev/null | ./my_script # Linux
stty echo onlcr
我们应当利用微粒或细微的“有线的”选择来解决这一问题。 不需要其他工具。
