MathematicaLicScript

#!/bin/bash
#Script name: MathematicaLicScript
#Description: Takes in current date, time & licenses being used and appends them to MathematicaLicStat.txt
#in CSV format. Normally runs hourly through cron.
#Extra note about carriage return (CR) character: If you get the error:
#         "bad interpreter: /bin/bash^M: nos uch file or directory
#It's because windows uses a different character to mark the end of the line as linux. In order to fix
#this problem, go to the directory of this file and run
#         sed -i -e 's/\r$//' MathematicaLicScript
#to remove these characters.

###Useful note: /[wolframPath]/Wolfram/MathLM/monitorlm displays the license manager status

###Extract total licenses and number of licenses used
#Extract line that has information about total licenses and licenses in use (starts with "Mathematica")
licenses=$(/[wolframPath]/Wolfram/MathLM/monitorlm |grep "Mathematica" -m1)
#Extract second (i.e. last) number from line (corresponds to total licenses)
totLics=$(echo $licenses | grep -o '[0-9]\+' | tail -n 1)
totLics=${totLics} #string to int
#Extract first number from line (corresponds to total licenses used)
usedLics=$(echo $licenses | grep -o '[0-9]\+' | head -n 1)
usedLics=${usedLics} #string to int

###Get date, time and licenses used
curDate=$(date "+%m/%d/%y")
curTime=$(date "+%H:%M:%S")

echo $curDate,$curTime,$usedLics >> ~/[dataPath]/MathematicaLicStat.txt
