[SOLVED] Script help on Copying and Renaming files

[Vectorman]

I need some scripting help.

I have a directory of jpg's. I want a script to go through this directory and all of it's subdirectories and find all the files labeled *_i1_*.jpg (useing * as wildcards) When it finds a file I need it to copy the file to a different directory and label it as the directory it came out of.

so if I have a file named v0001_i1_650.jpg in a directory named screenshots I want it copied to the directory named thumbnails and lable the file screenshots.jpg

Is this possible?

if so What would the script look like?

Thank you
Joel

Well... something like this might work. Create a script named "movefile", and make it executable. Make it look like this:

#!/bin/bash

# Get the directory the file is in
olddir="$(dirname "$1")"
# Get the last path component of that directory
newfname="$(basename "$olddir").jpg"

# Get the new filename
newpath="$PWD/thumbnails/$newfname"

echo "Old dir: $olddir"
echo "New filename: $newfname"
echo "New full path: $newpath"

# mv "$1" "$newpath" Then:

/path/to/movefile /path/to/one/of/the/files/blah.jpg

as a test. If the various directories and files are OK, then remove the comment from the "mv" command, comment out the three "echo" commands, and do this:

find /path/to/search -type f -name '*_i1_*.jpg' -exec /path/to/movefile {} \;

to actually move them all.

That worked sorta. what I found out is that I need a different directories name.

Here is a sample path listing

/pictures
/person
/thumbnails
/*_i1_*.jpg


I need the file named after the person directory.

Thank you for any and all help.

Ah. You could introduce another dirname before the basename:

# Get the directory the file is in
olddir="$(dirname "$1")"
# Get the directory above that
olddir2="$(dirname "$olddir")"
# Get the filename to create
newfname="$(basename "$olddir2").jpg"

Use the find command as follows :

find /start_dir -name '*jpg' -exec cp {} /new_dir \;

Where /start_dir is the directory that you are starting from and '*jpg' (or similar) is the pattern you are looking for.

[bwkaz]

Yes... but, err, that won't change the filenames. ;)

That command was basically my first reaction too -- but when I saw that Vectorman wanted to name the files the same as the directory that they came out of, I realized it'd be really hard to get find to do it. Hence the script. (find's -exec doesn't use a shell to do the execution, so if you need to do shell-like things in the command (like grabbing the output of dirname / basename, for example), it's much easier to just write a script.)

[Vectorman]

placing the second dir statement in the script worked like a charm.

Thank you so much, you saved me from hours of tedious work.
