Shell Programming and Scripting

Hi All,

I don't have much experience in scripting, and couldn't find anything that will help me to write a script I need, hopefully you can help me with it.

I have lots of files in one directory with the following file name pattern:

Code:

100001-something.ext1
100101-something2.ext2
100002-something3.ext1

etc.

I need to:
1. Loop through all the files in this directory,
2. Parse every file name and extract a number every file name starts with,
3. Check if there is a dir with this name already exists within this dir
4. If the dir doesn't exist then create it
5. Move parsed file to the create dir.

Thank you very much!

You use the following script to parse the file names and move them to the directory.

Code:

check=`find -maxdepth 1 -type f `
for file in $check
do
  dir=`echo $file | egrep  "[0-9]+.*$" | cut -d '-' -f 1`
  if [[ $dir != "" ]];then
    if [ -d $dir ]; then
      echo "$dir Directory Already Available"
      mv $file $dir
    else
      mkdir $dir
      mv $file $dir
    fi
  fi
done

If you don't have underlying directories:

Code:

for file in *
do
  dirname=${file%-*}
  mkdir -p ${PWD}/dirname
  mv "$file" ${PWD}/dirname
done

Thank you very much for your replies!

Since some subdirectories can already be in the directory, I used script from Nila and it worked like a charm!

No problem if you use the -p option of mkdir, from the man page:
