本文介绍了使用Bash重命名文件,删除前缀和后缀的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
范围太广;您可能需要将正则表达式应用于许多不匹配的文件.
如果当前目录中有很多个文件,则命令行可能会溢出.
It's too broad; you may need to apply the regex to a lot of non-matching files.
If there are a lot of files in the current directory, the command line could overflow.
我想使用bash重命名一堆文件,以转换此文件模式:
I want to rename a bunch of files using bash, transforming this file pattern:
prefix - name - suffix.txt进入这一个:
name.txt为此,我编写了以下脚本:
For that I wrote the following script:
find . -name "*.txt" | while read f do mv "${f}" "${f/prefix - /}" done find . -name "*.txt" | while read f do mv "${f}" "${f/ - suffix/}" done它可以工作,但是我想使用一个循环来执行重命名.有可能吗?
It works, but I'd like to perform the renaming using a single loop. Is it possible?
推荐答案另一种使用正则表达式的方法很有趣:
Another approach, for fun, using regular expressions:
regex='prefix - (.*) - suffix.txt' for f in *.txt; do [[ $f =~ $regex ]] && mv "$f" "${BASH_REMATCH[1]}.txt" done
实际上,在这里使用简单模式'* .txt'存在两个问题:
Actually, using the simple pattern '*.txt' here has two problems:
使用find使过程复杂,但更正确:
Using find complicates the procedure, but is more correct:
find . -maxdepth 1 -regex 'prefix - .* - suffix.txt' -print0 | \ while read -d '' -r; do [[ $REPLY =~ $regex ]] && mv "$REPLY" "${BASH_REMATCH[1]}.txt" done更多推荐
