在 bash 中循环几个文件扩展名

Question

I have a list of files in a folder and I want to just work on a few of them. The folder contains files with file.qc, file.qc.gz file.qc.stat file.qc.count and so on.

I want to write a loop in bash that will open only the file.qc and file.qc.gz, while ignoring other file extensions (such as qc.stats or qc.count)

Answer 1

Just specify multiple globs in your loop:

#!/bin/bash

# Gracefully cases where there are no matches
shopt -s nullglob

for f in *.qc *.qc.gz
do
  echo "Found: $f"
done

You can also write this shorter as *.qc{,.gz} , which expands to the same thing.
