您不需要使用管道.如果您使用的是bash
,请使用将进程替换为<(cmd)
,即实现重定向,使过程的输入或输出(某些命令序列)显示为临时文件.
You don't need to use a pipe. If you are using bash
use process-substitution as <(cmd)
i.e. to achieve a redirection where the input or output of a process (some sequence of commands) appear as a temporary file.
awk 'FNR==NR {col1[$1]++; col2[$2]++; next} {print $0, col2[$2] "/" length(col1)}' <(cut -f3 5- input) <(cut -f3 5- input)
