我想要排序一堆文件.我可以
sort file.txt > foo.txt mv foo.txt file.txt
但我需要第二个文件吗？
(当然,我尝试对file.txt> file.txt进行排序,但后来我得到了一个空文件.)
尝试：
sort -o file.txt file.txt
见http://ss64.com/bash/sort.html
`-o OUTPUT-FILE'
Write output to OUTPUT-FILE instead of standard output. If
OUTPUT-FILE is one of the input files,`sort' copies it to a
temporary file before sorting and writing the output to
OUTPUT-FILE.
