awk '

An awk approach:
awk -F'[:,]' '
NR == FNR {
if ( NR > 1 )
A[$1] = $2
next
}
{
if ( FNR == 1 )
...

First of all I don't see any matching values in field 7. So I guess you want to match field 8 instead of field 7.

Also your final output does not make any sense!
field 1,field 2,field 3,field...

try also:
awk '!/:/ {sub("\n$", "", s); $0="," $1} {s=s $0 "\n";} END {printf s}' input

You may try this also

$ cat <<eof | awk '{S=!/^[[:space:]]/? S RS $0 : S OFS $1}END{print S}' OFS=\,

As long as there is only one word on indented lines (as in your example), the following should work:
awk '
/^[[:space:]]/ {
o = o "," $1
next
}
{ if(o != "") print o

Rather than use /var/tmp, the more common place to put lock files is in /var/run.

You also need a trap statement to remove the lock if somebody or something terminates the script.

Create "lock file" when starting the script and remove it after script is done, for example:
if [ -f /var/tmp/script.lock ]; then
echo "Already running. Exiting."
exit 1

If the encryption doesn't protect him, or he learns better after you sell it to him, he will be very upset. So I'd try the key on drive (https://wiki.archlinux.org/index.php/Dm-crypt_with_LUKS)...

Plus, it's never secure enough:

Think about that. If the hard drive knows the secret needed to decrypt itself, so would anyone stealing that hard drive. It's like installing a steel security door then welding it open. What...

Hmm. You might be able to whitelist traffic to/from those interfaces by putting blanket rules to catch them, before any others:

-A INPUT -i eth1 -j ACCEPT
-A OUTPUT -i eth1 -j ACCEPT

-A INPUT...

There isn't any standard for this, but as a rule of thumb you don't want to include anything under /opt and /home.

The reverse process (converting an ISO to a VM appliance) should be pretty...

links=$(ip link |grep eth[0-7] |cut -d " " -f 2|cut -d":" -f1` | tr -s '\n' ' ')
for i in $links
do
echo $i
done

Is that what you are asking -- not clear to me, so I guessed. The cut and...

Ah, so you already have a VM image.

There's indeed a way to convert a VM appliance into a bootable/installable ISO. quemu-img does exactly that.

I have never used it though, but I bet Google...

Assuming you want to remove all assignment operator from output:
awk -F'=' 'NR==FNR{A[$1]=$2;next}/\$/{sub(/\$/,x);if(A[$2]) $2=A[$2]}{sub("=",OFS)}1' file.set file.conf

awk -F'=' 'NR==FNR{A[$1]=$2;next}/\$/{sub(/\$/,x);if(A[$2]) $2=A[$2]}1' OFS='=' file.set file.conf

Oh, and my procmailrc of course:

MAILDIR=/home/username/
VERBOSE=on

:0
mail/

Then you just need a cron entry to run the fetchmail executable once and a while and it will do the rest.

fetchmail is the traditional solution for this.

My ~/.fetchmailrc:

poll mail.zzzzzzzz.com
protocol pop3
user print@zzzzzzzz.com
pass qqqqqqqq
mda "/usr/bin/procmail -m...

You can easily do this with cut itself, using standard functionality:
cut -d, -f 1,6-9,11-

If your cut supports --complement then:
cut -d, --complement -f2-5,10 infile

Otherwise, try this:

awk -F, -vR="2,3,4,5,10" 'BEGIN{split(R,A,",");for(v in A) S[A[v]]=1}...

I think this might do it:


awk -F , '
NR == 1 { # capture list from the first line
for( i = 2; i <= NF; i++ )
pname[i-1] = $(i);
next;
}
{ ...

Whatever the data has whitespace, the only way to preserve is to double quote the field. Unless you can be for sure that there will be no white space in the field, otherwise I would recommend you to...

perl -F, -ane '($.==1)&&print;
chomp ($line = $_); open I, "< file2";
for (<I>) {
@x = split /,/;
if ($F[2] eq $x[0]) {
print "$line,$x[1]\n";
}
}' file1

awk 'NR==FNR{a[$2]=$1;next}{print $0","a[$2];}' FS="," file2 file1

Guru.
