Shell脚本执行多个目录

Question

How can I execute a script in multiple directories simultaneously suppose folder X contains directories ABCDE

all these directories contains a specific file on which script acts. thank you

Answer 1

这会将脚本应用于目录X内每个目录内的每个文件：

$ for file in X/*/*; do ./script "$file"; done

Answer 2

use function and run this function in background for each dir in dir X. for eg

func1()
{
   my dir = $1 # for dirs A,B,C etc
  statements. . . 
}

cd X
while read dir
do
    if [ -d $dir ]
    then
       func1 $dir &
    fi
done <<< "`ls`"
