shell脚本循环通过通配符匹配的目录

Question

I am trying to loop through directories that match a wildcard. This works fine in command line. But does not work in Shell script. Any idea?

   for dirs in /var/www/html/my.domain.com/v*; do echo $dirs; done;

The above command lists

  /var/www/html/my.domain.com/v1.0
  /var/www/html/my.domain.com/v1.2
  /var/www/html/my.domain.com/v2.0

Here is the Shell script version. Its not working:

 dirs=/var/www/html/my.domain.com/v*
 for dir in $dirs
 do
   echo "$dir"
 done

Tried this too:

dirs=`/var/www/html/my.domain.com/v*` #back quotes
for dir in $dirs
do
   echo "$dir"
done

Glob patterns like /var/www/html/my.domain.com/v* are a bash feature. It seems that bash is not the default shell on your system as you started the script using sh script.sh .

Make sure that you start the script using bash:

bash script.sh

If you are about to make the script executable directly using chmod +x script.sh , make sure that you are not missing to use the following shebang in the first line:

#!/bin/bash
