Shell Programming and Scripting

Hi All,

Output of the following command is ok so far ...

netstat -an | grep 192.168.156.1.16507 | awk '{print $5}' | awk '{FS="."} {print $5}'

1297
1350
1394
1211
1255
1259
4606
2184
2009
4890
1398
3941
1671
1780
51 [shivalpl1] dbi %


Now I want to redirect those outputs to lsof, but its not working. Suppose if I do it manually like this ...

[shivalpl1] dbi % lsof -iTCP:1297
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
cmddmn 58851632 dbi 10u IPv4 0xf1000e000113ebb0 0t400 TCP shivalpl1:dbi_cmddmn->s37stn6:sdproxy (ESTABLISHED)
52 [shivalpl1] dbi %

So the above looks good, but if I do redirect the putput of the above awk to lsof, its giving error. See the following command ...

[shivalpl1] dbi % netstat -an | grep 192.168.156.1.16507 | awk '{print $5}' | lsof -iTCP:`awk '{FS="."} {print $5}'`

Can anybody give me a hand to resolve this please ?

Regards.

Try if this works for you :

Code:

netstat -an | grep 192.168.156.1.16507 | awk '{print $5}' | awk '{FS="."} {print "lsof -iTCP:"$5}' | sh

Or use for loop (or while read line ) :

Code:

for i in $(netstat -an | grep 192.168.156.1.16507 | awk '{print $5}' | awk '{FS="."} {print $5}')
do
lsof -iTCP:$i
done
