在Linux下重命名文件，删除一些字符串

Question

我有很多这样的文件:

• download_agrupocqa_127_1656097965.tar.gz
• download_bjxkwris_127_1656097966.tar.gz
• download_climpieza_127_1656097965.tar.gz
• download_dhermagqu_127_1656097966.tar.gz

你知道将文件夹中的所有文件重命名为这种格式的命令吗?

• agrupocqa.tar.gz
• bjxkwris.tar.gz
• climpieza.tar.gz
• dhermagqu.tar.gz

表示删除download_和_127_1656097965

Answer 1

BASH:

for file in *.tar.gz ; do 
suffix="${file#download_}"      # this removes download_
prefix="${suffix%%_*.tar.gz}"   # this removes everything after underscore
mv "$file" "${prefix}.tar.gz"   # this renames the file
done

如果您有sed:

for file in *.tar.gz ; do 
newname=$(echo "$file" | sed 's/download_([^_]*)_[0-9_]*..*/1.tar.gz/')
mv "$file" "$newname"
done
