Hi,

How would I search for files that have the same name, but potentially
different case, living in the same directory? For example, I would
want to find files like

/dir1/image1.gif
/dir1/IMAGE1.gif

but I don't care about

/dir1/image1.gif
/dir1/dir2/image1.gif

? Hope this question makes sense, - Dave

Within a directory:

for file in *
do
if ls | grep -v "^$file\$" | grep -qi "^$file\$"
then echo "found similar matches for '$file'."
fi
done

There's probably other ways, whether that'll suit or not depends a lot on
your use case.

This awk program stores the converted filenames that it reads from stdin
in lowercase and prints any new filename that matches case-insensitive...

awk 'tolower($0) in f ; { f[tolower($0)] }'

You can feed files from a current directory

awk 'tolower($0) in f ; { f[tolower($0)] }' *

or (if case insensitive directories are not a problem) from a directory
tree

find . | awk 'tolower($0) in f ; { f[tolower($0)] }'

Just one way to approach the task.

Didn't know what I was thinking with the previous line; should have been

ls | awk '...' or ls */* | awk '...' or somesuch.

And since I am posting anyway I can point to the terse "golf version" as
well...

find . | awk 'f[tolower($1)]++'

How do you feel about:

/dir1/image1.gif
/DIR1/image1.gif

or:

/dir1/dir2
/dir1/DIR2

where dir2 and DIR2 are directories?

ITYM:

find . | awk 'f[tolower($0)]++'

or if the OP really only cares about files with matching names but does care
about differentiating directories with different case:

find . -type f |
awk -F'/' '{file=tolower($NF); sub(/[/][^/]+$/,"",$0)} f[$0 "/" file]++'

Usual caveat about file names that contain newlines.

Regards,

Ed.
