Find and Rename File using Terminal
I need help finding a file through terminal and then renaming it automatically.

Here is what I have so far to find the file:
Code:
cd /User/Applications
find . */SourceM.app/banner.png | while read line; do mv "$line" banner-.png; done

I want the script to rename the file "banner.png" to "banner-.png"

The issue I have with the above script is that it stops partially through searching the directory.

Any help would be appreciated.

Thank you

There's no particular reason for it to be stopping, though maybe you should be grateful it did: That'd systematically destroy every banner-*.png it finds, by moving it into the current directory, overwriting the last one.

Actually, because you told it to find . and never narrowed it down any more, it's going to rename each and every file and directory it finds into ./banner-.png. It may be freezing after the first move, unable to find anything else.

If there's anything left to operate on, you could try this:

Code:
# by default, find finds everything in the listed dirs.  -name 'banner.png' narrows it down to only that filename
find /path/to/search/in -name 'banner.png' |
while read FILENAME
do
        # replace /banner.png with /banner-.png, keeping full path
        NEWNAME="${FILENAME/\/banner.png/\/banner-.png}"
        mv -i "${FILENAME}" "${NEWNAME}"
done

Thank you, but I got this error:
Code:
mv: cannot move `/User/Applications/3BE2961D-A38F-46D4-A061-8AAE31F77EF3/SourceM.app/banner.png' to `/User/Applications/3BE2961D-A38F-46D4-A061-8AAE31F77EF3/SourceM.app\\/banner-.png': No such file or directory

I got it figured out, this is what i did:
Code:
find /User/Applications/ -wholename "*/SourceM.app/banner.png" | while read FILENAME; do NEWNAME="${FILENAME/\/banner.png//banner-.png}"; mv -i "${FILENAME}" "${NEWNAME}"; done

Code:
find /User/Applications/*/SourceM.app -type f -name "banner.png" | while read FILENAME
do
  NEWNAME=${FILENAME%.*}-.png
  mv ${FILENAME} ${NEWNAME}
done

^ Thank you, that is a much better way! Here is my final code:
Code:
# SourceM
if [ -f /User/Applications/*/SourceM.app/banner.png ]
	then
find /User/Applications/*/SourceM.app -type f -name "banner.png" | while read FILENAME
do 
NEWNAME=${FILENAME%.*}-.png
mv ${FILENAME} ${NEWNAME}
done
fi;

Not sure if the "if statement" is really needed. I guess it would come in handy for directories I am replacing multiple banners in.

Why does this not work?
Code:
find /User/Applications/*/Quick\ News\ UK\ Free.app/DownloadRSSFlashgForOtherApp.png | while read FILENAME; 
do NEWNAME=${FILENAME%.*}.bak; mv ${FILENAME} ${NEWNAME}; 
done;

The Directory has spaces, and when I printf $FILENAME, it only prints up to the first 'space'. So therefore it does not rename the file.

Since your filename includes space, you have to quota it.

Code:
find /User/Applications/*/Quick\ News\ UK\ Free.app/DownloadRSSFlashgForOtherApp.png | while read FILENAME; 
do NEWNAME=${FILENAME%.*}.bak; mv "${FILENAME}" "${NEWNAME}"; 
done;
