Invoking multi-line (G)AWK program in one line

Question

I'm wondering if it's possible to run a multi-line (G)AWK program through the shell where I can't have tabs or newlines.

It seems to crop up as an issue when I have variable assignments. For instance:

awk '{one=$1 two=$2}'

Answer 1

One possibility is to add semicolons between instructions, as you state.

However, return is also an option in most shells, just hit return before closing the awk instruction:

$ awk '{one=$1
> two=$2}' test.txt

note that > is added by the shell. This is also documented in the manual .

Answer 2

看起来只需添加标准分号就可以做到这一点：

awk '{one=$1;two=$2}'
