That works perfect until I try to output it from my array. (Which I dearly need).
Code:
#!/bin/bash
if [ 5.21 = $(nmap --version | awk '/Nmap/ { print $3 }') ]; then
i=5 t=report # field index and target text
else
i=2 t=Host
fi
/sbin/ifconfig | awk '/inet addr/ && !/127.0.0.1/ && !a[$2]++ {print substr($2,6)}' |
while read ip; do
first+=( "$(nmap -sP ${ip%.*}.0/24 | awk 'index($0,t) { print $i }' t="$t" i="$i" )" )
sleep 1
done
echo "${first[@]}"
The above outputs absolutely nothing. Don't bother running it.
That's happening because bash runs the highlighted while-loop portion of the pipeline in a subshell. Any modification to $first, in that subshell, is not visible in the parent shell (where the echo happens).
Perhaps the third time is indeed the charm? :
Code:
#!/bin/bash
if [ 5.21 = $(nmap --version | awk '/Nmap/ { print $3 }') ]; then
i=5 t=report # field index and target text
else
i=2 t=Host
fi
for ip in $(/sbin/ifconfig | awk '/inet addr/ && !/127.0.0.1/ && !a[$2]++ {print substr($2,6)}')
do
first+=( "$(nmap -sP ${ip%.*}.0/24 | awk 'index($0,t) { print $i }' t="$t" i="$i" )" )
sleep 1
done
echo "${first[@]}"
