BASH file rename
Rename All Files in a Folder with BASH
There are those weird occasions when you need to import a mass of images into an application, but they all have different names, and the application wants a file name pattern. Well, you can do this with a simple BASH file rename.
It would be so much simpler if your files looked like this:
In BASH, and probably most shells, you can do something like this…
ext="jpg";count=0;for f in `ls`;do let count=count+1 && mv $f $f$count.$ext;done
Change the value in ext=”” to whatever extension you want. You can also format the destination name, so maybe you want: Image_1.jpg in which case you would have: $f_$count.$ext
If this were in a script (say, bash-file-rename.sh), as opposed to on the command line, it would look more like this:
ext="jpg" count=0 for f in `ls` do let count=count+1 mv $f $f$count.$ext done
As you can see, adding a semi-colon to the end of each line allows you to pull them all up into a single line, much simpler for the command line.
