最简单的方法是使用重命名。ul它出现在大多数Linux发行版中

重命名。ul -o -v [oldFileExtension] [newFileExtension][搜索要应用的文件的表达式]

rename.ul -o -v .oldext .newext *.oldext

选项:

-o:不覆盖预先存在的. newnext

- v:详细

-n:演练

对于Ubuntu用户:

rename 's/\.html$/\.txt/' *.html

你也可以在Bash中创建一个函数，将它添加到。bashrc或其他文件中，然后在任何你想使用的地方使用它。

change-ext() {
    for file in *.$1; do mv "$file" "$(basename "$file" .$1).$2"; done
}

用法:

change-ext css scss

源代码的功能:https://stackoverflow.com/a/1224786/6732111

我用。bashrc写了这段代码

alias find-ext='read -p "Path (dot for current): " p_path; read -p "Ext (unpunctured): " p_ext1; find $p_path -type f -name "*."$p_ext1'
alias rename-ext='read -p "Path (dot for current): " p_path; read -p "Ext (unpunctured): " p_ext1; read -p "Change by ext. (unpunctured): " p_ext2; echo -en "\nFound files:\n"; find $p_path -type f -name "*.$p_ext1"; find $p_path -type f -name "*.$p_ext1" -exec sh -c '\''mv "$1" "${1%.'\''$p_ext1'\''}.'\''$p_ext2'\''" '\'' _ {} \;; echo -en "\nChanged Files:\n"; find $p_path -type f -name "*.$p_ext2";'

在"/home/<user>/example-files"这样的文件夹中:

/home/<用户> /示例文件: 中 file2.txt file3.pdf file4.csv

命令的行为是这样的:

~$ find-text
Path (dot for current): example-files/
Ext (unpunctured): txt

example-files/file1.txt
example-files/file2.txt


~$ rename-text
Path (dot for current): ./example-files
Ext (unpunctured): txt
Change by ext. (unpunctured): mp3

Found files:
./example-files/file1.txt
./example-files/file1.txt

Changed Files:
./example-files/file1.mp3
./example-files/file1.mp3
~$

这为我工作在OSX从.txt到.txt_bak

find . -name '*.txt' -exec sh -c 'mv "$0" "${0%.txt}.txt_bak"' {} \;
