Its about my second week in bash. It has proven hard to find tutorials or quality material. When searching for a forum I ran across this site so maybe I can see how it goes here

I am using a print shell script for printing everything in regards to .jpg to a file.

Code:


However I am trying to figure out how I can write the code to only print to a csv based on a size.

I thought it might have been:

Welcome George!

I don't get this line:

You mean you want to check all file sizes, then treat the corresponding files, if they are equal/greater than/... to a certain number?
Or perhaps you want to check the length of the filenames, or what?

I want to check the exact filesize of an image to 34.9kb. This size file is the exact file size of an image we process from a server that says no file exists. Now I have a folder that has the clients thumb images based on name so I cant sort through a huge folder all day. Im trying to make a script that will print to a csv file based on the image size. I thought if i declared filesize as a variable it may work that way but Im unsure how to declare a jpeg size as a variable and process it through an if statement. I can print the entire jpeg image folder name and size with stat but need to take it further.

The exact size of the file is 40318. I need to take files that are that size and print it to a csv

Something like this?

i tried to run it and it doesnt work. Can you also explain what it is doing?? I understand the for THIS do THAT and done, IF this THEN this END. But I dont understand the I would imagine like other code would be the equal than. Dont I still need to declare f??

How do you know that it doesn't work?



Loop through each JPG file located in the directory dir.
If a JPG file's size is equal to 40318 bytes, then print the corresponding filename and the said size to results.csv.



This is the part where you check whether the size of the file being processed is equal to 40318 bytes.



Yep, == means equal to.



Nope, f is the file being processed in the loop.
It'll take each filename as its value, one by one.

Try this line in your shell if you don't get it yet:

I copy and pasted the code in a .sh file and changed dir to /images for the location foder of images and ran the code. Nothing happened. I tried changing:



to



and nothing happened

images/ then, not /images.
