Bash Script for Adding Printers In RHEL 6.7
 
Ok,

It has been a while since I wrote a bash script and I need a little help.

I'm charged with migrating printers from our virtual environment to our all-in-one cloud system. I been adding the printers manually via the lpadmin command, but I'm coming up on a huge migration were I have to add about 100 printers, and my wrist hurt just thinking about adding them manually. I have written a script in bash doing a basic for loop, but I can remember how to make the loop cat more than one file.


Code:
#!/bin/bash

Printer_List=printer-list1
Device_List=/root/scripts/printers/deviceURI-list1
PPD_List=ppd-list1

echo
echo

for x in `cat $Printer_List`;do
  echo "Adding Printer For $x"
  lpadmin -p "$x" -E -v "$Device_List" -P "$PPD_List"

  cupsaccept $x
  cupsenable $x
done

echo
Any help would be awesome.

P.S sorry the code format is wrong. I cant remember how you guys make it all pretty.

You can cat more than one file simply by giving multiple arguments to cat command (e.g. cat file1 file2 file3 ...)

Since you're doing a variable you can set the variable equal to multiple files:

Code:
#!/bin/bash

Printer_List="printer-list1 printer-list2 printer-list3"

for x in `cat $Printer_List`;do
echo "Adding Printer For $x"
done
You can put code tags around your code by highlighting it and clicking the # icon for "code". (Or manually type left "[" followed by the word "code" closing with "]" at beginning of your code then doing same thing at end of code except you put in "/code" instead of just "code".

What you are saying makes sense, but I can not seem to put it into action. How would I do this with a long lpadmin command?

I dont seem to understand how to make the script assign different variables for the different list.


Code:
lpadmin -p "printer_name" -E -v "device_URL" -P "device_ppd"

Ah, I misunderstood. On rereading I see you're trying to get separate values from 3 separate files for different variables in your lpadmin. Assuming you have the same number of lines in each file with each having a single column you can use the "paste" command to join them together as 3 separate columns. You'd then use a while loop in combination with the "read" command that sets variables based on input.


Code:
#!/bin/bash

Printer_List=printer-list1
Device_List=/root/scripts/printers/deviceURI-list1
PPD_List=ppd-list1

echo
echo

paste $Printer_List $Device_list $PPD_List |while read name uri ppd
do
  echo "Adding Printer For $name"
  lpadmin -p "$name" -E -v "$uri" -P "$ppd"

  cupsaccept $name
  cupsenable $name
done

echo

That did the trick. Thank you so much for your help. You are a life saver.
