    <p>I'm a bit frustrated here with trying to get what seems like a simple bash script to run properly. I believe this is due to very long file names, or spaces within the file.</p> <p>In short, I'm trying to pull data from the file command, and rename pictures in a directory to their proper file type as some seem to be mis labeled. For example a .png file is actually a .jpg file. Which results in some image viewers not displaying them. Here is the script i'm using.</p> <pre><code>#!/bin/bash for NAME in $(ls); do if [ "$(file $NAME|grep GIF)" ]; then echo "Renaming ${NAME} to ${NAME%.*}.gif" mv ${NAME} ${NAME%.*}.gif elif [ "$(file $NAME|grep JPG)" ]; then echo "Renaming ${NAME} to ${NAME%.*}.jpg" mv ${NAME} ${NAME%.*}.jpg elif [ "$(file $NAME|grep PNG)" ]; then echo "Renaming ${NAME} to ${NAME%.*}.png" mv ${NAME} ${NAME%.*}.png else echo "No Change For ${NAME}" fi done </code></pre> <p>The echo at the end was just to see why it was failing, this is what I see:</p> <pre><code>No Change For 20097489744.jpeg No Change For 24902583463 </code></pre> <p>Then it just hangs, why? Because I believe that file contains spaces... I looked around a bit on mass renaming all the files in the directory by just incrementing the file names up, IE: 1.jpg 2.png 3.gif however EVERYTHING I have found online was not to increment a file rename job, but rather to remove numbers from the name and things like it.. So, I've hit a wall, short of renaming 130K files by hand (Not going to happen! lol)</p> <p>I''d highly appreciate any input from the brainiacs out there!</p> <p>Thanks and happy holidays!</p>

    1. COIf your files could have spaces in the name, make sure you wrap your variables in quotes. e.g. `mv "${NAME}" "${NAME%.*}.gif"`, also, use `grep -i` to make your search case-insensitive.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
