Why does regex `“.pdf”` match `/…/pdf…/…` in gawk, but not in mawk?












0















From How can I extract only the pid column and only the pathname column in the lsof output?



awk '{ for (i=9; i<=NF; i++) {

    if ($i ~ "string" && $1 != "wineserv" && $5 == "REG" && $NF ~ ".pdf") {

        $1=$2=$3=$4=$5=$6=$7=$8=""

        print

    }

}}'


The regex ".pdf" matches /.../pdf.../... in gawk, but not in mawk. I wonder why?



Thanks.

My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
