在Linux中多个目录中的文件上运行Shell脚本

Question

I have a shell script which needs to be run on paired files (eg file1 and file2 ). For each pair, there should be 5 output files generated in the current directory. How can I run a shell script on multiple paired files in different directories?

To be more specific, the structure looks like the following:

pair1: /x/y/z/1/file1 and x/y/z/1/file2
pair2: /x/y/z/2/file1 and x/y/z/2/file2

I want to run the same shell script on multiple pairs like these two. The output needs to be saved in the current directory, eg /x/y/z/1/ for pair1 .

Answer 1

Run the script as:

myscript /x/y/z/1/file1 /x/y/z/1/file2 /x/y/z/2/file1 /x/y/z/2/file2

The script contains:

#!/bin/bash

create_five_files_with_pair() {
  cp $1 outfile1
  cp $2 outfile2
  cat $1 $2 > outfile3
  cat $2 $1 > outfile4
  paste $1 $2 > outfile5
}

while test $# -gt 1
do
  cd $(dirname $1)
  create_five_files_with_pair $(basename $1) $(basename $2)
  shift
  shift
done
