如何在特定字元後刪除多個文件名中的字元串？

我在一個文件夾中有多個具有這種名稱格式的文件

01. file one-sdvanv-12lknl.srt
01. file one-sdvanv-12lknl.mp4
02. file two-afdsmakl-asdfafdaf.srt
02. file two-afdsmakl-asdfafdaf.mp4
03. file three-adfadaasd-asdfadfafad-adad1d1das.srt
03. file three-adfadaasd-asdfadfafad-adad1d1das.mp4

現在如何刪除字元串之後-文件名將如下所示

01. file one.srt
01. file one.mp4
02. file two.srt
02. file two.mp4
03. file three.srt
03. file three.mp4

for file in *; do
   ext=.${file##*.}                #Gets file extension
   [ "$ext" = ".$file" ] && ext="" #If file had no extension, set it to empty string
   nostr=${file%%-*}               #Remove everything after -
   mv "$file" "$nostr$ext"
done

您可以像這樣使用 bash 參數替換：

for i in *; do
 # ${i%%-*} get everything before the first '-' (use ${i%-*} for the last '-')
 # ${i/.*} remove everything after the '.'
 # ${i##${i%.*}} remove everything except everything after the last '.'
 mv "${i}" "${i%%-*}${i##${i%.*}}"
done
