Shell Programming and Scripting

correct but i want to save a bash file so i can use it again and again

This is the epl2 code for the demensions
N q609 A100,10,0,5,2,2,N," " P1

You said in post #4 that you didnt want a file so you can use again and again...

From their EPL2 examples, perhaps something like

Code:

for ((N=1; N<3; N++))
do
        CODE=`printf %08d $N`
        cat <<EOF
N
B1,5,0,3,3,7,40,B,"$CODE"
P1
EOF
done | sed 's/$/\r/' > /dev/usblp0

I think he means he wants a bash script which generates lots of similar labels, instead of a text file containing EPL2 commands which he edits by hand.

That's only the text to clear the buffer. What code would you actually use to print a label? And how do you usually send these codes to the printer?

This is what i got so far you sent me on the right track but
IS it possible to put two lines in a variable

Code:

#!/bin/bash
newlabel="N"
labelwidth="q609"
labeltext='A100,10,0,5,2,2,N,"PC109":)\n TExt:)'
endlabel="P1"

echo $labeltext

In the future, please place source code and program output inside code tags when posting. It will prevent the problems you are having, like smilies appearing in the middle of your code.

[ code ] #!/bin/bash ... [ /code ] without the spaces in the tags and it will appear as

Code:

#!/bin/bash ...

It's even easier than you think to put two lines into a variable. Don't put in \n -- put in a real newline.

Code:

VARIABLE="line1
line2
line3"

Also, be sure to quote the variable when you use it, to prevent the shell from processing any of the whitespace.

Code:

echo $variable # This may convert newlines into spaces
echo "$variable" # this will not process the text inside, printing it raw
