Script to show IP's

[guif]

Hi!
I'm trying to order my outpu as I like but I have problems.
I have this:

/sbin/ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}' > $LOG_TMP

for i in $LOG_TMP; do
    IPS=`echo $i`
done

the result is:

[5.5.5.9]
[5.5.5.10]

but I would like to see as:

[5.5.5.9] [5.5.5.10]

How can do this???

How about:

/sbin/ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}' > $LOG_TMP

ips=""
for i in $LOG_TMP; do
    ips="${ips} ${i}"
done

echo $ips

[guif]

the output is the same as my script. I only change the last echo for a more

[nmset]

/sbin/ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}' > $LOG_TMP

ips=""
while read i; do
    ips="${ips} ${i}"
done < $LOG_TMP

echo $ips

Can't understand how

for i in $LOG_TMP

can produce

[5.5.5.9]
[5.5.5.10]
or
[5.5.5.9] [5.5.5.10]

LOG_TMP is not a list of values.

/sbin/ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}' > $LOG_TMP

ips=""
while read i; do
    ips="${ips} ${i}"
done < $LOG_TMP

echo $ips

Can't understand how



can produce


LOG_TMP is not a list of values.

It doesn't. That line just loops through each value in the list. The line:

 ips="${ips} ${i}"

Creates a variable containing all of the values in the list. So after the loop has complete the state of the application should be that:

ips=" [5.5.5.9]  [5.5.5.10]"

Then the echo will print this to stdout

[Kieren]

Okay, this works for me:

LOG_TMP=/tmp/test
/sbin/ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}' > $LOG_TMP

ips=""
for i in `cat ${LOG_TMP}`; do
    ips="${ips} ${i}"
done

echo $ips

Output:
