Does anyone have any idea of how I can make something like the code below run recursively?
I'll run it on a tree of directories all with different names and all containing a sequence of .dpx files. I've tried to do it using find and exec but can't get it to work right.
What it needs to do is find .dpx files in any sub-directory and move them into a new directory called 2880x1640, in their current directory.
.../xyz_XXX_XXX/xyz_XXX_XXX.00000.dpx needs to become
.../xyz_XXX_XXX/2880x1640/xyz_XXX_XXX.00000.dpx
The file and it's parent directory are named identically, if that makes any difference.
It'll run in a bash shell.
Code:
for f in "$@"
do
mkdir $f/2880x1640
mv $f/*.dpx $f/2880x1640
done
Off the top of my head (so there might be better solutions)...
Assuming that the current working directory is the root of the portion of the file tree that you wish to parse, here are two possibilities. The first, I believe, is more efficient, but isn't bash friendly (ksh only). The second should run in either bash or ksh. Run to see what it would create/move and then remove the 'echo' to actually do the work.
Code:
#!/usr/bin/env ksh
# ksh only!
typeset -A dhash
find . -name "*.dpx"| while read f
do
path=${f%/*}
if [[ -z ${dhash[$path/]} ]]
then
echo "mkdir $path/2880x1640"
dhash[$path/]=1;
fi
echo mv $f $path/2880x1640/
done
Code:
# not efficient as it has to stat the target directory for every file, but works in bash.
find . -name "*.dpx"| while read f
do
path=${f%/*}
if [[ ! -d $path/2880x1640 ]]
then
echo "mkdir $path/2880x1640"
fi
echo mv $f $path/2880x1640/
done
Yes! The they both work great, except they continue to move files that are already moved ... xxxx/2880x1640/2880x1640/ ...
This is a bad thing. I need some way of preventing this from happening.
My original code searched for the directory name ???_???_v* and then executed on that, that way it would just fail if there was already a 2880x1640 directory.
Oops, hadn't considered a rerun, or that there might be files already in the directory. Something like this would prevent it from trying to move files that had been moved:
Code:
find . -name "*.dpx"| while read f
do
path=${f%/*}
if [[ $path != *"2880x1640"* ]] # skip if file is already below a 2880x directory
then
if [[ ! -d $path/2880x1640 ]]
then
"mkdir $path/2880x1640"
fi
mv $f $path/2880x1640/
fi
done
You can apply the same technique to the other script if you went with that one.
Hi,
I have got a file with 6K records and I want to delete 500 records from this file which match the values present in another file.

I manage a spam filter for the organization I work for. I've been trying to get the others here to stop white listing by domain name since that can be easily spoofed. One of the obstacles, however, is that there doesn't seem to be an easy way to determine the legitimate outgoing SMTP server IP... (0 Replies)
The /src file is obviously designed to contain source code, so when I download programs, I should put them in /src (because they contain the source files + the executables)? What do most people do with the executables? Do they copy them to /bin, make links to them in /bin, or just leave them in... (4 Replies)

I'm developing a generic script to catenate all files found in a given directory.
The problem I've got is that the depth of the given directory is unknown, so I end up with some catenated directories. My unix isn't that hot and I'm at a loss.
Heres an extract from the script
