with some limitations, you can have filenames named the same way as your variables if that suits your fancy ... the main thing is that you understand what is in the file just like you would want to...

you can name your variables very much any way you want to (see man sh, man ksh, man bash, etc.) ... however ... it is always good to be able to easily figure out what the variables stand for just by...

hope it's clearER.

while read llcooljatt
do
echo $llcooljatt
done < ip_list

dunno if this would be clearer ...

# this is in sh

for ip in `cat ip_list`

What comment?
It is obvious no?
Or what don't you understand?

Why don't you try executing the code and see?
$ip here will have values 1.1.1.1 2.2.2.2 etc depending on the contents of the file ip_list!

while read ip
do
check_GE-VLANStats-P3 $ip
check_GE-VLANStats-P3 $ip
done < ip_list

That is a simple while loop. It reads each line from the file ip_list into the variable ip. And within the loop, it is being echo-ed here. You missed the do and echo.

And regarding you second...

while read ip
do
check_GE-VLANStats-P3 $ip
done < ip_list


I didn't understand your second point

--ahamed

mmm... Try this...

IPLIST="1.1.1.1 1.1.1.2"
for ip in $IPLIST
do
check_GE-VLANStats-P3 $ip
done
--ahamed

Use the full path of ssh in that case

ret=$( /usr/local/bin/ssh $ip /opt/tools/utils/HUB/GEW-VLANStats-P3 )
Please make sure the variable IPLIST is populated correctly with the required IP...

If you have ssh enabled, try this...


IPLIST="192.168.1.1 192.168.1.2"
for ip in $IPLIST
do
ret=$( ssh $ip /full/path/to/script )
echo $ret
done

You don't have ssh? :eek:
Paste the output of which ssh

hmm ok i missed it.:rolleyes:



then final version (added to new file to old files)
# awk -F, 'NR==FNR{a[$1FS$2FS$3]++;next}{b[$1FS$2FS$3]++}

@ygemici : the file arguments which is fed to awk is to be noted. 20111229.csv *.csv

20111229.csv is fed in twice and hence it takes care of both new and old with the logic.

nawk -F, ## determine the our FS=,
'NR==FNR{a[$1FS$2FS$3]++;next} ## execute this until the NR equal to FNR
so NR means number of input records and it will be increase as long as tha read new...

i don't understand exactly what you want but i guess output should not contain counts which in the new file about old records..

for example
# cat old*
NE:221726,SHELF:8,SLOT:1,01:00:02,Wed Dec...

nawk -F, 'NR==FNR{a[$1OFS$2OFS$3]++;next} a[$1OFS$2OFS$3]{b[$1OFS$2OFS$3]++}
END{for(i in b){if(b[i]-1&&a[i]!=b[i]){print i";\t\t"b[i]}else{print "NEW:"i";\t\t"b[i]} } }' OFS=, 20111229.csv *.csv
...

then try like this
# nawk -F, 'NR==FNR{a[$1OFS$2OFS$3]++;next}{b[$1OFS$2OFS$3]++}
END{for(j in b){bx++};for(i in a){for(j in b){if(i==j){cc=a[i]+b[j]}else{cn++}
if(cn==bx){print "NEW ENTRY FOUND...

maybe you can try like this [ as far as i understand what you want ]
# awk -F, 'NR==FNR{a[$1OFS$2OFS$3]++;next}{b[$1OFS$2OFS$3]++}
END{for(i in a){for(j in b){if(i==j){cc=a[i]+b[j]}else{cn++};...

When you run that piece of code, what is the result? Any error?

I don't like much your approach to the problem. It is difficult to understand, and more if I can't test it.

This is my shot in the dark:

nawk -F, '
NR==FNR {
a[$1OFS$2OFS$3]++;
next...

What does this mean?

Regards,
Birei

echo 20111125.csv; nawk -F, 'NR==FNR{a[$1OFS$2OFS$3]++;next} a[$1OFS$2OFS$3]{b[$1OFS$2OFS$3]++}
END{for(i in b){if(b[i]-1){print i"\t\t"b[i]}else{print "NEW :"i} } }' OFS=, 20111125.csv *.csv | sort...
