尝试:
xargs --show-limits
Your environment variables take up 2446 bytesPOSIX upper limit on argument length (this system): 2092658POSIX smallest allowable upper limit on argument length (all systems): 4096Maximum length of command we could actually use: 2090212Size of command buffer we are actually using: 131072
每个参数没有限制,但是整个命令行的总长度没有限制。在我的系统(Fedora 15 / zsh)中,它接近2Mb。(第4行)。
