Bash-使用通配符重定向 [英] Bash - Redirection with wildcards

问题描述

我正在测试使用通配符进行重定向.像这样:

I'm testing to do redirection with wildcards. Something like:

./TEST* < ./INPUT* > OUTPUT

有人有什么建议吗?谢谢.

Anyone have any recommendations? Thanks.

推荐答案

有一个名为TEST *的程序，必须将各种重定向转换为称为INPUT *的程序，但问题是有很多TEST程序，并且它们都有不同的编号，例如TEST678.我想做的是将所有随机INPUT文件推入所有TEST程序中.

There is a program called TEST* that has to get various redirection into into called INPUT*, but the thing is there are many TEST programs and they all have a different number, e.g. TEST678. What I'm trying to do is push all the random INPUT files into all the all TEST programs.

您可以写:

for program in TEST*            # e.g., program == 'TEST678'
do
  suffix="${program#TEST}"      # e.g., suffix == '678'
  input="INPUT$suffix"          # e.g., input == 'INPUT678'
  "./$program" < "$input"       # e.g., run './TEST678 < INPUT678'
done > OUTPUT
