Question

This is probably a simple one to answer, but I’m stuck, so here goes.

sed '3d' filename    # (or something like that)

I’m having trouble trying to use a $VARIABLE instead of the number.

Anyone know how to get this to work, or any alternative options?

Answer 1

Did you mean this:

bash$ VARIABLE=3
bash$ sed "${VARIABLE}d" filename

(I’m not sure if this is correct use of the sed command, I just know that’s how you would use a variable next to a letter in bash syntax.)
