问题 I built a library and I want to install the library to /usr/local/lib using coreutils install . The result of the build looks as follows: libfoo.so -> libfoo.so.1 libfoo.so.1 -> libfoo.so.1.1 libfoo.so.1.1 I want to retain the symbolic links and install the files as is to /usr/local/lib . However, if I run install libfoo* /usr/local/lib the symbolic links are resolved and /usr/local/lib looks as follows: libfoo.so libfoo.so.1 libfoo.so.1.1 In other words, these are all real files and no

问题 Consider this program: use std::io::BufRead; use std::io; fn main() { let mut n = 0; let stdin = io::stdin(); for _ in stdin.lock().lines() { n += 1; } println!("{}", n); } Why is it over 10x as slow as the GNU version of wc? Take a look at how I measure it: $ yes | dd count=1000000 | wc -l 256000000 1000000+0 records in 1000000+0 records out 512000000 bytes (512 MB, 488 MiB) copied, 1.16586 s, 439 MB/s $ yes | dd count=1000000 | ./target/release/wc 1000000+0 records in 1000000+0 records out

问题 I'm working with huge files of (I hope) UTF-8 text. I can reproduce it using Ubuntu 13.10 (3.11.0-14-generic) and 12.04. While investigating a bug I've encountered strange behavoir $ export LC_ALL=en_US.UTF-8 $ sort part-r-00000 | uniq -d ɥ ɨ ɞ ɧ 251 ɨ ɡ ɞ ɭ ɯ 291 ɢ ɫ ɬ ɜ 301 ɪ ɳ 475 ʈ ʂ 565 $ export LC_ALL=C $ sort part-r-00000 | uniq -d $ # no duplicates found The duplicates also appear when running a custom C++ program that reads the file using std::stringstream - it fails due to

问题 I'm using brew to retrieve and install common GNU versions of terminal commands and utils with brew install coreutils . Then in my .bash_profile I'm including their PATH with if [ -d $(brew --prefix coreutils)/libexec/gnubin ]; then PATH="$(brew --prefix coreutils)/libexec/gnubin:$PATH" fi so far so good, I can use use the GNU version of coreutils. The problem comes from ls . Apple implement ACL that is not implemented on GNU ls . I discovered this by banging my head many times and not

问题 I wanted read coreutils info, but I could not find it. Now, I wonder where the info documents in my computer (mac or linux). I want to know how I can install info files.
