Add suffix to all files in the directory with an extension
提问by user1757703
How to add a suffix to all files in the current directory in bash?
如何在bash中为当前目录中的所有文件添加后缀？
Here is what I've tried, but it keeps adding an extra .pngto the filename.
这是我尝试过的，但它不断向.png文件名添加一个额外的内容。
for file in *.png; do mv "$file" "${file}_3.6.14.png"; done

for file in *.png; do
mv "$file" "${file%.png}_3.6.14.png"
done
${file%.png}expands to ${file}with the .pngsuffix removed.
${file%.png}扩展到${file}与.png后缀去掉。

You could do this through rename command,
你可以通过重命名命令来做到这一点，
rename 's/\.png/_3.6.14.png/' *.png
Through bash,
通过 bash，
for i in *.png; do mv "$i" "${i%.*}_3.6.14.png"; done
It replaces .pngin all the .pngfiles with _3.6.14.png.
它.png在所有.png文件中替换为_3.6.14.png.
${i%.*}Anything after last dot would be cutdown. So.pngpart would be cutoff from the filename.mv $i ${i%.*}_3.6.14.pngRename original .png files with the filename+_3.6.14.png.
${i%.*}最后一个点之后的任何内容都会被删减。所以.png部分将从文件名中截断。mv $i ${i%.*}_3.6.14.png使用文件名+_3.6.14.png 重命名原始 .png 文件。
