I'm using a mac. I need to get a list of files in a folder without their extensions being included in the list. This is because I need a list of products for a website import and conveniently, the image names are the same as the product names. However, my list needs to NOT have the extensions.

I've gotten a list of file names by using terminal and was able to copy them into a text file. Only problem is that the file names include the extension, ".jpg" Using the list I have from terminal, I will now have to go through my text file and manually delete the extension from each file name (there are over a thousand) and this is going to take a long time. Is there an easier way? Can I get terminal to display a list of file names without their extensions so I can copy and paste it into a list? Or can I remove the extensions from these files, then list them in terminal and copy their names? Is there another way? Confused here. I'm not a programmer, just a website design.

Hope someone can help with this. Thanks everyone!

Borrowed from Stackoverflow:

ls -1 | sed -e 's/\..*$//'

I tried flagging as duplicate but didn't work.

One of my own solutions given we know the file extension(s). 

find -type f -exec basename -s '.jpg' "{}" \;

So find all files as opposed to directories - type f and then execute basename for each. The -s allows you to specify a known suffix to remove.

Another alternate solution: from SU

    As the comments on the answer you linked to point out, this removes the first . (and everything to the right of it), so Mr.Coffee_machine.jpg becomes Mr.  That might be good enough for this OP's needs, but it's a dangerous assumption to make, given that the question doesn't have any example file names, and it's a poor solution to the problem of "removing filename extensions".

  • Good point I don't know what the file names are.

If you have your list of files in the file "in.txt", run this script to get the list of files without the extension in "out.txt" :

#!/bin/bash    
while read fullfile; do
    filename=$(basename "$fullfile")
    filename="${filename%.*}"
    echo $filename >> out.txt
done <in.txt

Do you use vi (or vim)?  If you do, then, since you've already got the JPEG file names in a text file, the easiest way may be to edit that file with vi / vim and type

:%s/\.jpg$//

which says, on every line in the file, look for .jpg occurring at the end of a line, remove it, and replace it with nothing.  If there are some lines that don't end with .jpg, that's OK; they will be ignored (skipped over).  If you've got multiple product names (file names) per line, as in

        hammer.jpg              screwdriver.jpg         wrench.jpg

just leave out the $ and add g and say

:%s/\.jpg//g

which will remove all occurrences of .jpg, even if they aren't at the end of a line.
