loop through directories and move files

ratcateme · 11-17-2008, 09:16 PM

I am look to script a bash script that will loop through a directory go into sub directory and move files that are say .fileb to a new directory
it has to work like this

Code:

start/dira/1.filea
start/dira/1.fileb
start/dira/2.filea
start/dira/2.fileb
start/dirb/1.filea
start/dirb/1.fileb
start/dirb/2.filea
start/dirb/2.fileb
//run script
start/dira/1.filea
start/dira/2.filea
start/dirb/1.filea
start/dirb/2.filea
end/dira/1.fileb
end/dira/2.fileb
end/dirb/1.fileb
end/dirb/2.fileb

i tried mv start/*/*.fileb end/*/
but that tried to put all the files in
end/dira/
how can i do this?

Scott.

IIUIC:

Code:

for file in `find start -type f -print`
do
    echo $file
    fname=`basename $file`
    dir=`dirname $file`
    if [[ $fname =~ "fileb" ]]
    then
        # move it
        if [[ $dir =~ "dira" ]]
        then
            mv $file end/dira
        elif [[ $dir =~ "dirb" ]]
        then
            mv $file end/dirb
        else
            echo "unmatched dir $dir"
        fi
    fi
done

thanks for the reply
but there will be heaps of dirs
so
start/dira
start/folder
start/dirc
start/example
.....
and so i want to do it without having to enter each dir into the code.
and they will change often to.

These two statement are contradictory. What are exactly your requirements? The script suggested by chrism01 does not enter any directory (no cd statements).

i want it to loop through say start/ and get all the directory names then go through each directory it found and find all files with the .fileb extension and move them to end/(directory name from start/)/name.fileb

If they (dirs) are only start+one level and you want the same end+one level dirs, you just slice the dirname using eg cut

Code:

subdir=`echo start/dirb|cut -d'/' -f2`

gives 'dirb', which you then append to end. Obviously you don't hardcode 'start/dirb' that's just an example.

A modified version of the Chris' script. This checks for the existence of the destination directory, otherwise create it. Hope this is what you are asking for:

Code:

#!/bin/bash
for file in `find start -type f -name '*.fileb' -print`
do
  # strip out the front of the path till start/
  path=${file#*start/}
  # strip out the file name
  dir=${path%/*}
  # create the destination dir if missing
  test -d end/$dir || mkdir -p end/$dir
  # move it
  echo mv $file end/$dir
done
