 |
|
Hi!
Does anyone know an expression for find, a special program or something that detects case collisions in file names?
I want to recursively find files in a directory that would appear as the same file in case insensitive file systems.
Thanks!

Something like this?
| Code: | | find directory -iname filename -print |

The file's name has to be variable, as it should find and print out any file that could cause problems.

I think something like this should do it (please give some comments if you find any errors or improvements):
| Code: |
#!/bin/bash
folder=$1
for filename in $(find $folder -type f -iname "*");
do
count=$(find $folder -iwholename $filename | wc -l);
if [ $count -gt 1 ]; then
echo "$count: $filename";
fi
done

It might work.
But according to find man pages iwolename option is an insensitive alias to path option, so if your system if fully case insensitive (and if you have /USR/Local and /usr/local for example), i'd suggest to change:
| Code: | | count=$(find $folder -iwholename $filename | wc -l); |
into:
| Code: | | count=$(find `dirname $filename` -maxdepth 1 -iname `basename $filename` -print|wc -l); |
The -maxdepth 1 option is important if you don't want to find recursively into the subdirectories. |

Thanks, I didn't have paths in mind. I don't think i've something like /usr /USR. It's mainly about iles like dsc1000.jpg and DSC1000.JPG. or protocol.tex and Protocol.tex  Things can get doubled up if you are copying files from/to FAT/NTFS USB sticks to whatever.
EDIT: The above won't work if you have spaces in file names. Better use while instead of for:
| Code: |
find "${folder}" -type f -iname "*" | while read filename;
do
#count=$(find "${folder}" -iwholename "${filename}" | wc -l);
count=$(find `dirname "${filename}"` -iname `basename "${filename}"` -print | wc -l);
if [ "${count}" -gt 1 ]; then
echo;
echo "${count}: ${filename}";
else
echo -n ".";
fi
done
