Subject: Use '[[:space:]]' instead of '\s' to support POSIX awk
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cda6e65688a691707744b99eeabef1d0804171cf;p=users%2Fdwmw2%2Fvpnc-scripts.git

Use '[[:space:]]' instead of '\s' to support POSIX awk

The `\s` is a GNU extension to awk and doesn't work on BSD's awk.  Use
`[[:space:]]` instead to work with BSD's awk.
