Adding a variable to a column in Linux

geodave

Hello everyone,

I'm trying to add a predefined variable to a column in a text file in Linux. For example:

awk '{ print $1+2.50 }' file1.txt > file2.txt

works fine if I hard code the number 2.50 in the awk program. How would I go about making the 2.50 value a variable that I can predefine before the awk statement in a shell script?

Any help or suggestions would be greatly appreciated!

DERP=2.50
awk '{ print $1+$DERP }' file1.txt > file2.txt

I assume you're doing this in a shell script?

Thank you, ardichoke, and sorry for the tardy reply. Yes, I am doing this in a shell script, and it worked beautifully.
