Rename multiple files with Mac shell script
Simple renaming and renumbering script for multiple files
num=0 for j in *.jpg do mv "$j" `printf "myFILE.%05d.jpg" $num` num=`echo "$num + 1" | bc` done
Usage: In any text editor, modify the script so that the extension in the second line (here .jpg) exactly matches the extension of the files you want to modify. Also, change the file name in line four (here myFILE) to whatever name you want to use. In the Terminal, cd to the directory with your files. Paste the script to the terminal, hit enter.
Note, the way this is set up, the script will rename every file of the specified .extension in the current directory.
–
Replace file name suffix:
Another script. This script changes the suffix of each specified file in a directory. In this example from “myName_000_01.JPG” to “myName_000.jpg”
for i in *.JPG do mv $i `basename -s _01.JPG $i`.jpg done
Edit the the first line of the script so that it works on the appropriate files. In this example we have several files that have the extension of .JPG in common. Each of these files will be renamed.
The “mv” unix command is used to rename the files. Using the “basename” utility and the “-s” flag we can designate what part original name we want to keep, rather the suffix we want to remove. In this example the suffix we want to remove is “_01.JPG”.
Specify the new suffix that you want to add (here it’s “.jpg”).
Next, open a terminal window. Navigate to the directory where your files reside. Enter “sh” in the window, hit enter. Paste the script, and hit enter. That’s it.

Creating a Maya batch render script
Creating a Maya batch render script for a PC using Windows has always been straightforward in my experience. You simply write a text file with the following code:
render /path/to/myFile.mb
Make the file executable by changing the extension to .bat. Double click the file to launch the render.
The renderer will use settings that were selected when the project was saved. Those settings can be over-ridden with render flags. See Render Flags below for render flags and options.

For the Mac, it can be slightly less straightforward. Follow these instructions, found on Autodesk, The Area
Issue
You are on Mac OS X and you want to render several files one after another using a batch script.
Solution
To batch render multiple scene files, you need to create a shell script, for example: myRender.sh.
1. Using a text editor (Applications > Textedit), enter the render command for each individual scene on a separate line.
#!/bin/bash
Render –r sw scene1.mb
Render –r sw scene2.mb
Render –r sw scene3.mb
In some cases, you may need to enter the complete path of the Render command. It is located here:
/Applications/Autodesk/maya2009/Maya.app/Contents/bin/Render
(of course, different for later versions of the software)
2. Save the file on your desktop as: myRender.sh.
3. You will need to change the file permissions of myRender.sh to 755.
Open the Maya Terminal (Applications > Autodesk > Maya2009 > Maya Terminal) and type:
chmod 755 /Users/YOUR-USERNAME/Desktop/myRender.sh
4. Now run the script from the Maya terminal by typing:
/Users/YOUR-USERNAME/Desktop/myRender.sh
(note! A shortcut to typing file paths in the terminal: Just drag the file to the terminal window!)
Code:
#!/bin/bash /Applications/Autodesk/maya2009/Maya.app/Contents/bin/Render -rd /path/to/render/output/folder /path/to/myFile.mb

Render Flags
Render flags are “options” code. For example in Render -rd, -rd is the flag, which allows you to set the exact render directory, i.e. where your rendered images will be saved.
Render -rd /path/to/render/output/folder
Do a search in the help for more render flags (options):
render -h in the terminal.
/Applications/Autodesk/maya2009/Maya.app/Contents/bin/Render -h
—
Popular Render Flags:
-proj
#Use this flag to ensure you are rendering to the proper project: -proj /path/to/projectDirectory
-s, -e
#specify start and end frames: -s 0 -e 100
-r
# Specify renderer: -r mr for mental ray (or : sw, hw, etc)
-rt
# Render threads, specify number of cpu threads, I use -rt 8 for my Mac Pro Quad (Mental Ray only)
-rl
# Specify render layer by name: -rl layer1
-cam
#Specify camera to render by name
-rd
# specify render image path: -rd /path/ to/image/folder/
-im
# specify image name: -im myImageName
—
If you are using Render layers use the following flags and setup:
-rl boolean|name(s)
Set up like this:
Render -rl layer1 /path/to/file1.mb
Render -rl layer2 /path/to/file1.mb

Maya fresnel texture connections MEL script
Connect this network to the reflectivity attribute of a shader to get the fresnel effect, ie reflections that increase in intensity as the rendered surface turns away from the camera.
Use this script to generate the fresnel network. Connect the ramp’s outAlpha to the Reflectivity attribute of your material.
string $myRamp = `shadingNode -asTexture ramp`; string $myNode = `shadingNode -asUtility place2dTexture`; connectAttr ($myNode + ".outUV") ($myRamp + ".uv"); connectAttr ($myNode + ".outUvFilterSize") ($myRamp + ".uvFilterSize"); removeMultiInstance -break true ( $myRamp + ".colorEntryList[1]"); setAttr ($myRamp + ".colorEntryList[0].color") -type double3 .5 .5 .5 ; setAttr ($myRamp + ".colorEntryList[0].position") 0; setAttr ($myRamp + ".colorEntryList[2].color") -type double3 0.1 0.1 0.1 ; setAttr ($myRamp + ".colorEntryList[2].position") 1; setAttr ($myRamp + ".interpolation") 4; string $mySamplerInfo = `shadingNode -asUtility samplerInfo`; connectAttr -f ($mySamplerInfo + ".facingRatio") ($myRamp + ".uCoord"); connectAttr -f ($mySamplerInfo + ".facingRatio") ($myRamp + ".vCoord");
Select a material that has a “Reflectivity” attribute then run this script. The proper connections will be made automatically.
string $selShader[] = `ls -sl`; string $myRamp = `shadingNode -asTexture ramp`; string $myNode = `shadingNode -asUtility place2dTexture`; connectAttr ($myNode + ".outUV") ($myRamp + ".uv"); connectAttr ($myNode + ".outUvFilterSize") ($myRamp + ".uvFilterSize"); removeMultiInstance -break true ( $myRamp + ".colorEntryList[1]"); setAttr ($myRamp + ".colorEntryList[0].color") -type double3 .5 .5 .5 ; setAttr ($myRamp + ".colorEntryList[0].position") 0; setAttr ($myRamp + ".colorEntryList[2].color") -type double3 0.1 0.1 0.1 ; setAttr ($myRamp + ".colorEntryList[2].position") 1; setAttr ($myRamp + ".interpolation") 4; string $mySamplerInfo = `shadingNode -asUtility samplerInfo`; connectAttr -f ($mySamplerInfo + ".facingRatio") ($myRamp + ".uCoord"); connectAttr -f ($mySamplerInfo + ".facingRatio") ($myRamp + ".vCoord"); connectAttr ($myRamp + ".outAlpha") ($selShader[0] + ".reflectivity");
