将所有以相同前缀开头的文件放在linux的文件夹中

Question

I have different files in some old data.

They are in the same folder.

They are grouped by the prefix.

I want to move all the files starting with the same prefix in a folder named with the same prefix.

Looking for a script which does it automatically.

EDIT 1 The script has to look by itself that how many prefixes are there and then group

Thanks

Answer 1

As a starting point, how about an ls -1 listing of all the files, piping to an awk command to get all the unique prefixes:

xxx
yyy
zzz
www
...

Then, use the output of the awk commmand and loop through to create the prefix directory and move all files into it as @Noufal Ibrahim suggested:

mkdir ${prefix} && mv ${prefix}* prefix

I'm no awk expert, but off the top of my head, I'm thinking the awk script would be something along the lines of:

BEGIN {
    // initialize associative array $x
}

{ $x[prefix($0)] = 1; }

END {
   // foreach key in $x:
       print $key
}
