遍历目录并删除文件

Question

I want to Loop through the homefolders and validate, if the path /home/*/.ssh/authorized_keys exists. If it exists, I want to remove the file .../.ssh/disabled_authorized_keys for the user, that has already the authorized_keys file in his homefolder.

I have created this script so far, but it will remove all disabled_authorized_keys and not just for the users who have the authorized_keys.

 for i in /home/*/.ssh/authorized_keys;
 do ii=`echo $i|awk -F '/' '{print $3}'` ;
 rm /home/$ii/.ssh/disabled_authorized_keys;
 done

Thank you in advance. (I'm an absolute beginner in bash scripting!)

Answer 1

Try this:

for path in /home/*/.ssh/authorized_keys; do
    rm "$(dirname "$path")"/disabled_authorized_keys
done

It will grumble on stderr if disabled_authorized_keys does not exists, but will not "crash".

More about dirname .

Answer 2

for dir in /home/*/.ssh; do
    [[ -e $dir/authorized_keys ]] && rm "$dir/disabled_authorized_keys"
done

[[ -e file ]] checks if file exists. Read && as "if-then".
