awk and quote

Hello,

How do you protect the simple qote ' using awk's printf ?

I've tried using backslash, it doesn't seems to work properly ?

Thanks

Not " but ' --> simple quote

If you prefer a dirty method you can use tr to substitute,

ex:

ls | awk -F " " '{printf "\"" $1}' | tr \" \'

I can't belive that there is no way in awk to print a simple quote !

I found something interesting,

awk 'END {printf("Some '\''single'\'' quoted stuff\n");}'

My Above example works when I tried this,

ls | awk -F " " '{printf ("'\''''\''\n") $1}'

Too much complicated though ...!!!

There is a way :

#!/bin/sh

QUOT="'"

echo " " | awk -v quot=$QUOT '{
printf("this is a quote %s\n",quot);
}'

Pedantic perhaps, and perfectly obvious to some perhaps, but I'd like to point out that this has very little to do with awk.
It is a shell usage problem. The strict answer to the question is: Nothing: You do not need to protect a single quote in awk printf. Witness:

$ cat > x
BEGIN {print "test'"}
$ awk -f x
test'

Cheers,
Hein.
