UNIX for Dummies Questions & Answers

Hello:

I have this script:

#!/bin/bash
#for loop
for ip in `cat ips`
do
ping $ip | grep "is alive">>pingtestlog
done


And its working properly with this input:

ericadm@amxcruas1> cat ips
10.196.60.4
10.196.61.210
10.196.62.73
10.196.61.152

And this output:

ericadm@amxcruas1> cat pingtestlog
10.196.60.4 is alive
10.196.61.210 is alive
10.196.62.73 is alive
10.196.62.43 is alive



But I will like to include the date on the output filename, and inside the file.

Can you please help me with this!!!

Code:

#!/bin/bash
outputfile="pingtestlog"$(date +%Y%m%d)
date > $outputfile
while read ip
do
 ping $ip | grep "is alive" >> $outputfile
done < ips

Thanx!
But I got the following error:

ericadm@amxcruas1> /bin/sh ./pingdate.sh
./pingdate.sh: syntax error at line 2: `outputfile="pingtestlog"$' unexpected

can you execute this alone in the console.

Code:

 
outputfile="pingtestlog"$(date +%Y%m%d)
echo $outputfile
 
or 
 
outputfile="pingtestlog".`date +%Y%m%d`
echo $outputfile

ericadm@amxcruas1> /bin/sh ./file.sh
./file.sh: syntax error at line 2: `outputfile="pingtestlog"$' unexpected
ericadm@amxcruas1> cat file.sh
#!/bin/bash
outputfile="pingtestlog"$(date +%Y%m%d)


The last one seems to be working:

outputfileericadm@amxcruas1> /bin/sh ./file2.sh
pingtestlog.20110928
ericadm@amxcruas1> cat file2.sh
#!/bin/bash
outputfile="pingtestlog".`date +%Y%m%d`
echo $outputfile

Thanx!!! itkamaraj

It's working:

ericadm@amxcruas1> /bin/sh ./pingdate.sh
ericadm@amxcruas1> cat pingtestlog.20110928

10.196.60.4 is alive
10.196.61.210 is alive
10.196.62.73 is alive
10.196.61.152 is alive
ericadm@amxcruas1> cat pingdate.sh
#!/bin/bash
outputfile="pingtestlog".`date +%Y%m%d`
date > $outputfile
while read ip
do
ping $ip | grep "is alive" >> $outputfile
done < ips

You whole script (at least what you mention) has been done:

Code:

It's not a script, but it's very full featured and handy.
