replace `awk` command with `gawk` for Debian Jessie

[ArcEye]

awk fails and throws error awk: not an option: --re-interval despite it appearing in the usage print

Substituting gawk works correctly.

Hi @ArcEye. On my Debian Jessie awk links to gawk:

andy@thinkbabe:~$ which awk
/usr/bin/awk
andy@thinkbabe:~$ ls -la /usr/bin/awk
lrwxrwxrwx 1 root root 21 Nov 15  2014 /usr/bin/awk -> /etc/alternatives/awk
andy@thinkbabe:~$ ls -la /etc/alternatives/awk
lrwxrwxrwx 1 root root 13 Nov 17  2014 /etc/alternatives/awk -> /usr/bin/gawk
andy@thinkbabe:~$

So it looks like you've another awk installed than the default gawk. Thanks for the patch, I'll merge it.

Btw, just out of curiosity, can you tell me which awk doesn't have "--re-interval"? "awk --version" should tell

[ArcEye]

It is peculiar certainly. They should be exactly the same.

I don't have an /etc/alternatives entry for awk, just the binary, but the switch is supposed to exist.

gawk is a pattern scanning and processing language.
By default it reads standard input and writes standard output.

Examples:
    gawk '{ sum += $1 }; END { print sum }' file
    gawk -F: '{ print $1 }' /etc/passwd
