Primero que nada, debemos tener una instalación actualizada de ImageMagick. En el sitio oficial se encuentran las instrucciones para instalarlo: http://www.imagemagick.org/script/binary-releases.php#macosx.

Luego copiamos el siguiente script en algún lugar dentro de nuestro filesystem. Por ejemplo en /usr/local/bin.

#!/usr/bin/env bash

# Source picture
FF=$1
FW=`identify -format %w ${FF}`;
FH=`identify -format %h ${FF}`;

# Watermark (must be a transparent background GIF or PNG)
WF=/path/to/watermark.png
GEO=+10+10
WXM=20
WW=`identify -format %w ${WF}`;
WH=`identify -format %h ${WF}`;

# Resizing watermark to 25% of source picture's shortest side
MX=$FH
if [ $FH -gt $FW ]; then
    MX=$FW
fi
WX=$[ $[ $[ $MX * 25 ] / 100 ] - ${WXM} ]

# Output filename
OF=`echo "${FF}" | sed -e 's,\.jpg$,-WM\.jpg,g'`

# Watermarking...
composite \
    \( ${WF} -resize ${WX} \) \
    ${FF} \
    -geometry ${GEO} \
    -gravity southeast \
    ${OF}

exit 0

Para ejecutarlo, simplemente se invoca de la siguiente forma:

#!/usr/bin/env python

A simple script for making random passwords, WITHOUT 1,l,O,0.  Because

#Import Modules
import sys
from random import Random

rng = Random()

righthand = '23456qwertasdfgzxcvbQWERTASDFGZXCVB'
lefthand = '789yuiophjknmYUIPHJKLNM'
allchars = righthand + lefthand
alternate_hands = True

try:
    passwordLength = int(sys.argv[1])
except:
    #user didn't specify a length.  that's ok, just use 8
    passwordLength = 16

try:
    passwordQty = int(sys.argv[2])
except:
    #user didn't specify a length.  that's ok, just use 8
    passwordQty = 1

for q in range(passwordQty):
    for i in range(passwordLength):
        if not alternate_hands:
            sys.stdout.write( rng.choice(allchars) )
        else:

    sys.stdout.write( "\n" )

Para ejecutar, simplemente se debe ejecutar de la siguiente forma (suponiendo que se guarda den tro de $PATH con el nombre “passgen”:

Para que funcione el script, se debe uno posicionar en la carpeta en la que se tenga al menos 1 foto JPG, y ejecutar el script.

#!/usr/bin/env bash

DIR=`pwd -P`
W=720
H=$[ $[ $W * 2 ] / 3 ]
BITRATE=$[ $[ $W * $H ] / 64 ]
FPS=$1
FFMPEG=`which ffmpeg`

# Defaults
if [ "X$FPS" == "X" ]; then
    FPS=24
fi

for FILE in `ls -C1 ${DIR}/*.jpg`; do
    NEW_FILE=`printf "TL-%05d.jpg" "$I"`
    sips --resampleHeight ${H} ${FILE} --out ${NEW_FILE}.tmp.jpg
    sips --padToHeightWidth ${H} ${W} ${NEW_FILE}.tmp.jpg --out ${NEW_FILE}
    rm -f ${NEW_FILE}.tmp.jpg
    I=$[ $I + 1 ]
done
